Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a wireless access device and a communication system. Background Art

[0003] Wireless access devices, such as wireless routers, are used to provide internet access and wireless coverage. A wireless access device can be thought of as a repeater, forwarding wireless or wired broadband network signals to nearby user equipment (UE) via an antenna. Wireless access devices strive for high gain, wide coverage, fast response, and excellent operational stability. However, current wireless access devices on the market often fail to meet these multiple requirements simultaneously.

[0004] Summary of the Invention

[0005] The embodiments of the present application provide a wireless access device and a communication system for solving the problem of how to increase the coverage range of a high-gain antenna, improve the response speed, and enhance the operational stability while ensuring the high gain of the wireless access device.

[0006] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0007] In a first aspect, a wireless access device is provided, comprising a housing, multiple directional antennas, and a drive device. The multiple directional antennas are disposed within the housing and arranged in a circular array, with the central axis of the circular array of the multiple directional antennas being a first axis. Each directional antenna radiates signals in a direction away from the first axis. The beams of the multiple directional antennas are respectively located within multiple sectors, the multiple sectors being arranged around the first axis, with the vertices of the multiple sectors located on the first axis. The drive device is disposed within the housing and is configured to drive the multiple directional antennas to rotate relative to the housing to adjust the beam directions of the multiple directional antennas within the multiple sectors.

[0008] This allows directional antennas to have high gain characteristics and support signal enhancement for single-user and mesh networks. Furthermore, the beams of multiple directional antennas are located in multiple sectors. A driving device drives the multiple directional antennas to rotate within each sector, switching the beam directions of the multiple directional antennas. This increases the coverage range of the directional antennas and improves coverage in edge blind spots. While maintaining the same coverage range, compared to an electrically switched approach, the number of directional antennas required can be reduced, saving costs. Furthermore, driving the multiple directional antennas to rotate within their respective sectors reduces the rotation angle of the directional antennas. This reduces lag and improves response speed for user device tracking scenarios, enhancing the user experience. Furthermore, the smaller rotation angle of the directional antennas reduces the risk of feeder cable tangling, kinking, and wear, thereby improving device operational stability. Therefore, compared to existing technologies, the wireless access device provided in this embodiment simultaneously features high gain, wide coverage, high-speed response, and superior operational stability.

[0009] In one possible implementation of the first aspect, the wireless access device further includes a first bracket, to which multiple directional antennas are fixed. Furthermore, a driving device includes a driving member connected to the first bracket. The driving member is configured to drive the first bracket to rotate about an axis, with the axis of rotation of the first bracket driven by the driving member being collinear with the first axis, thereby driving the multiple directional antennas to rotate synchronously and adjust the beam pointing directions of the multiple directional antennas within multiple sectors. This synchronous driving method features a simple driving device structure, low cost, and ease of assembly, thereby reducing the cost and assembly difficulty of the wireless access device. This can improve the edge coverage performance of single-user devices or the coverage performance of some multi-user devices.

[0010] In a possible implementation of the first aspect, the wireless access device further includes a first bracket, which is fixed relative to the housing. The directional antenna includes a radiator and a reflector. The radiators of the multiple directional antennas are fixed to the first bracket, and the reflectors of the multiple directional antennas are rotatable around an axis relative to the radiators. The driving device is used to drive the reflectors of the multiple directional antennas to rotate around their rotation axes to adjust the beam directions of the multiple directional antennas within multiple sectors. In this way, by fixing the radiators of the multiple directional antennas and driving the reflectors of the multiple directional antennas to rotate, the beam directions of the directional antennas can be adjusted. During the adjustment process, the positions of the radiators of the multiple directional antennas and the circuit board assembly are fixed, and the feeder wires connected between the radiators and the circuit board assembly do not swing, thereby minimizing the possibility of the feeder wires being wound, tangled, or worn.

[0011] In one possible implementation of the first aspect, the reflector is positioned between the radiator and the first axis. The reflector is an arc-shaped plate, with its centerline collinear with its rotational axis. The arc-shaped plate has opposing concave and convex surfaces, with the concave surface facing the radiator and the convex surface facing the first axis. A drive device is configured to rotate the arc-shaped plate about its centerline to adjust the beam pointing direction of the multiple directional antennas within multiple sectors. This minimizes the impact on the performance of the directional antennas when the reflector rotates.

[0012] In a possible implementation of the first aspect, the driving device includes a plurality of driving members, the number of the plurality of driving members is equal to the number of the plurality of directional antennas, and the plurality of driving members correspond one-to-one to the plurality of directional antennas, and each driving member is connected to the reflector of the corresponding directional antenna, and the driving member is used to drive the reflector to rotate around its center line. The control principle of this structure is simple and easy to control. The driving mode is an asynchronous driving mode, which can simultaneously meet the high-speed Internet access requirements of multiple user devices to improve the edge coverage performance of multiple sectors and multiple users. It has better flexibility and a wider range of applications. Different coverage strategies can be used under different optimization strategies, such as global throughput optimization or VIP priority, business scenario priority, etc.

[0013] In a possible implementation of the first aspect, the driving device includes a driving member, a driving gear and a plurality of driven members. The driving member is connected to the driving gear, and the driving member is used to drive the driving gear to rotate. The driven member is a gear or a rack extending along an arc. The plurality of driven members are respectively arranged on the reflective plates of the plurality of directional antennas, and the axes of the plurality of driven members are respectively collinear with the center lines of the reflective plates where they are located. The plurality of driven members are arranged circumferentially around the driving gear and mesh with the driving gear to drive the plurality of driven members to rotate around their axes respectively. This driving mode is a synchronous driving mode. In this driving mode, since the rotation axes of the plurality of directional antennas are not collinear with the first axis, the position accuracy of the reflective plates of the plurality of directional antennas relative to the first bracket and the relative position accuracy between the reflective plates of the plurality of directional antennas are relatively low, which can simplify the installation difficulty. At the same time, the structure of the driving device can be designed to achieve different angular velocities and / or different rotation directions of the reflective plates of the plurality of directional antennas to meet the needs of different application scenarios.

[0014] In a possible implementation of the first aspect, the wireless access device further includes a first bracket, which is fixed relative to the housing. Multiple directional antennas are connected to the first bracket and can rotate about axes. A drive device is used to drive the multiple directional antennas to rotate about their respective rotation axes to adjust the beam pointing directions of the multiple directional antennas within multiple sectors. This drive method is a synchronous drive method. In this drive method, because the rotation axes of the multiple directional antennas are not collinear with the first axis, the positional accuracy of the multiple directional antennas relative to the first bracket and the relative positional accuracy between the multiple directional antennas are lowered, which can simplify installation. At the same time, the structure of the drive device can be designed to achieve driven rotation of the multiple directional antennas at different angular velocities and / or different rotational directions to meet the needs of different application scenarios.

[0015] In a possible implementation of the first aspect, the driving device includes a plurality of driving members, the number of the plurality of driving members is equal to the number of the plurality of directional antennas, and the plurality of driving members correspond one-to-one to the plurality of directional antennas, and each driving member is connected to the corresponding directional antenna, and the driving member is used to drive the directional antenna to rotate around its rotation axis. The control principle of this structure is simple and easy to control. The driving mode is an asynchronous driving mode, which can simultaneously meet the high-speed Internet access requirements of multiple user devices to improve the edge coverage performance of multiple sectors and multiple users. It has better flexibility and a wider range of applications. Different coverage strategies can be used under different optimization strategies, such as global throughput optimization or VIP priority, business scenario priority, etc.

[0016] In a possible implementation of the first aspect, the driving device includes a driving member, a driving gear and a plurality of driven members, the driving member is connected to the driving gear, and the driving member is used to drive the driving gear to rotate. The driven member is a gear or a rack extending along an arc, and the plurality of driven members are respectively arranged on the plurality of directional antennas, and the axes of the plurality of driven members are respectively collinear with the rotation axes of the directional antennas. The plurality of driven members are arranged circumferentially around the driving gear and mesh with the driving gear to drive the plurality of driven members to rotate around their axes respectively. This driving device can realize the simultaneous driving of multiple directional antennas with one driving member, so the cost is low. At the same time, the transmission ratios between the driving gear and the plurality of driven members can be designed separately so that the rotation angular velocities of the plurality of directional antennas are different, thereby adapting to different application scenarios.

[0017] In one possible implementation of the first aspect, the transmission ratio between the driving gear and the driven member may be 1. In this way, during operation of the antenna assembly, the rotational angular velocity of the driving member, the rotational angular velocity of the driving gear, and the rotational angular velocity of the driven member are the same, thereby simplifying control.

[0018] In a possible implementation of the first aspect, the driving device also includes a shifting assembly. The shifting assembly is used to enable the driving gear to be selectively separated from at least one of the multiple follower members. In this way, by shifting the gears of the shifting assembly, at least one follower can be stopped from rotating to fix the position of the reflector or directional antenna, so that the at least one directional antenna maintains the current coverage state. At the same time, at least one other directional antenna is driven to rotate to change its beam pointing. This driving mode is an asynchronous driving mode, which can meet the high-speed Internet access requirements of multiple user devices at the same time. It has better flexibility and a wider range of applications. Different optimization strategies can be used under different optimization strategies, such as global throughput optimization or VIP priority, business scenario priority, etc.

[0019] In a possible implementation of the first aspect, there is a gap between the driving gear and the multiple driven members. On this basis, the shift assembly includes multiple transmission gears and multiple linear drive mechanisms. The multiple transmission gears are all in the first position, and the multiple transmission gears are respectively arranged in the gaps between the driving gear and the multiple driven members, and the transmission gears are meshed with the driving gears and the driven members so that the driving gears and the driven members are indirectly meshed with each other via the transmission gears. The multiple linear drive mechanisms are respectively connected to the multiple transmission gears, and the linear drive mechanisms are used to drive the transmission gears to move in a direction parallel to the first axis so that the transmission gears switch between the above-mentioned first position and the second position. When the transmission gear is in the second position, the transmission gear is located outside the gap between the driving gear and the driven member and is separated from the driving gear and the driven member. In this way, by controlling the multiple linear drive mechanisms, the driving gear can be selectively meshed with one of the multiple driven members to achieve gear shifting. This structure is simple and has a high degree of structural compactness.

[0020] In one possible implementation of the first aspect, when the transmission gear is in the first position, the transmission ratio of the gear transmission mechanism consisting of the driving gear, the transmission gear, and the driven member can be 1. In this way, during operation of the antenna assembly, the rotational angular velocity of the driving member, the rotational angular velocity of the driving gear, and the rotational angular velocity of the driven member are the same, simplifying control.

[0021] In a possible implementation of the first aspect, the linear drive mechanism includes a magnetic part, an electromagnet, an elastic reset part, and a control circuit. The arrangement direction of the magnetic part and the electromagnet is parallel to the first axis, one of the magnetic part and the electromagnet is fixed on the transmission gear, and the other of the magnetic part and the electromagnet is fixed relative to the first bracket. The elastic reset part is connected to the transmission gear. The control circuit is connected to the electromagnet, and the control circuit is used to control the power on or off of the electromagnet. When the electromagnet is energized, there is a magnetic attraction between the electromagnet and the magnetic part, and the magnetic attraction drives the transmission gear to move from the first position to the second position, and the elastic reset part is deformed to accumulate the elastic reset force. When the electromagnet is de-energized, the magnetic attraction between the electromagnet and the magnetic part disappears, and the elastic reset force drives the transmission gear to reset from the second position to the first position. In this way, the transmission gear is driven back and forth between the first position and the second position. This structure is simple and easy to control.

[0022] In one possible implementation of the first aspect, the control circuit includes a power supply circuit, a selector switch, and a processor. The selector switch is disposed between the power supply circuit and the electromagnets of the plurality of linear drive mechanisms. The processor is connected to the selector switch and is configured to control the selector switch so that the power supply circuit selectively supplies power to the electromagnet of at least one of the plurality of linear drive mechanisms.

[0023] In a possible implementation of the first aspect, the number of sectors is N, where N is a positive integer greater than 1, and the central angle of each sector is (360 / N)°. Multiple sectors are connected end-to-end along the circumference of the first axis. That is, along the circumference of the first axis, one radial edge of two adjacent sectors overlaps, and other areas other than the radial edge do not overlap. In this way, multiple sectors cover a 360° range around the first axis, providing a wide coverage range. The likelihood of two adjacent directional antennas covering the same target user is low, facilitating rational resource allocation.

[0024] In a possible implementation of the first aspect, the number of directional antennas and the number of sectors are both 3.

[0025] In one possible implementation of the first aspect, the wireless access device further includes a circuit board assembly, multiple feeder cables, and a second bracket. The multiple feeder cables are respectively connected between the radiators of the multiple directional antennas and the circuit board assembly. The second bracket is fixed relative to the housing and includes a support plate positioned between the multiple directional antennas and the circuit board assembly. The support plate is provided with at least one cable trough, and the multiple feeder cables are routed through the at least one cable trough. This facilitates routing of the multiple feeder cables through the support plate while maintaining a neat appearance.

[0026] In one possible implementation of the first aspect, there are multiple cable troughs, distributed along a circular array. The central axis of the circular array of the multiple cable troughs is the second axis, and the second axis is collinear with the first axis. At least one feeder line is passed through each cable trough. In this way, the multiple feeder lines are separated by the multiple cable troughs, thereby preventing the feeder lines from becoming tangled or tangled.

[0027] In one possible implementation of the first aspect, the wire trough may be an elongated trough, wherein the elongated trough is an arc-shaped trough extending about a second axis, and the second axis is a centerline of the arc-shaped trough. In this way, the feeder line can slide along the wire trough during swinging, thereby reducing the risk of the feeder line being stuck and worn in the wire trough.

[0028] In one possible implementation of the first aspect, the wire trough is an elongated trough having a first end and a second end relative to each other. The trough extends from the first end to the second end about a second axis, and the distance from the first end to the second axis is not equal to the distance from the second end to the second axis. The elongated trough extending about the second axis means that the central angle of the elongated trough relative to the second axis is greater than 0°. Specifically, the central angle of the elongated trough relative to the second axis refers to the angle between a perpendicular line from the first end of the elongated trough to the second axis and a perpendicular line from the second end of the elongated trough to the second axis. Each wire trough is provided with at least one feeder line, which is capable of sliding along the trough. In this way, in the direction about the second axis, the second end of one of the two adjacent wire troughs is located on the side of the first end of the other wire trough that is farther away from or closer to the second axis. In other words, the two adjacent wire troughs are staggered. This can increase the central angle of the wire trough relative to the second axis, improve the swinging flexibility of the feeder line, and reduce the risk of winding, tangling, and wear. At the same time, it can ensure that there is a connection area of ​​a certain width between two adjacent wire grooves, so as to stably connect the first area to the second area, thereby ensuring the support stability of the first area for the driving member.

[0029] In one possible implementation of the first aspect, the path extending from the first end to the second end of the cable trough can be a straight line or an arc, and the arc can be arched in a direction away from the second axis or in a direction toward the second axis. In some embodiments, the path extending from the first end to the second end of the cable trough is an arc, and the arc is arched in a direction away from the second axis. This allows the feeder to slide smoothly along the cable trough, reducing wear.

[0030] In one possible implementation of the first aspect, the number of wire slots is equal to the number of directional antennas, with the multiple wire slots corresponding to the multiple directional antennas. A feeder line connected to each directional antenna is respectively routed through the corresponding wire slot. This ensures a moderate number of wire slots, ensuring both the structural strength of the support plate and the ease of winding and tying the feeder lines.

[0031] In one possible implementation of the first aspect, the number of wire troughs is M, where M is a positive integer greater than 1, and the central angle of each wire trough relative to the second axis is greater than or equal to (360 / M) degrees. In this way, the sum of the central angles of the multiple wire troughs relative to the second axis is greater than or equal to 360 degrees, thereby ensuring the swing flexibility of the feeder line as much as possible and reducing the risk of wire jamming and wear.

[0032] In a possible implementation of the first aspect, the second bracket further includes a plurality of support columns, which are disposed on a side of the support plate away from the plurality of directional antennas, and the plurality of support columns are evenly arranged around the edge of the support plate. The wireless access device further includes a plurality of omnidirectional antennas, which are respectively disposed on the plurality of support columns. The omnidirectional antenna exhibits 360° uniform radiation in a plane perpendicular to the central axis of the beam, and can achieve short-range coverage within a 360° range of the plane, which can meet the access needs of ordinary users. At the same time, by supporting the omnidirectional antenna with the support column, there is no need to set up an additional support structure, which can reduce the structural complexity of the antenna assembly and reduce the difficulty of assembly. Moreover, the plurality of omnidirectional antennas can support the transmission and reception of multiple different channel signals, thereby increasing the versatility of application of the wireless access device.

[0033] In a possible implementation of the first aspect, there are four support columns and four omnidirectional antennas, the four omnidirectional antennas correspond one-to-one to the four support columns, and each omnidirectional antenna is arranged on the support column corresponding to the omnidirectional antenna.

[0034] In one possible implementation of the first aspect, the housing includes a lower housing and an upper housing. The lower housing includes a base plate and a first side frame, the first side frame being disposed around the base plate, the first side frame and the base plate forming a first storage space, the second bracket being located within the first storage space, the support plate being spaced apart from and opposite the base plate, a plurality of support columns being located between the support plate and the base plate, and the plurality of support columns being connected to the base plate. The upper housing includes a cover plate and a second side frame, the second side frame being disposed around the cover plate, the second side frame and the cover plate forming a second storage space, an end of the second side frame away from the cover plate being connected to an end of the first side frame away from the base plate, and the second storage space being connected to the first storage space. This housing is easy to process and assemble.

[0035] In one possible implementation of the first aspect, a circuit board assembly includes a radio frequency transceiver system, at least one switching switch, and a processor. The radio frequency transceiver system includes at least one radio frequency transceiver, wherein the number of the at least one radio frequency transceiver is less than the sum of the number of directional antennas and the number of omnidirectional antennas. Multiple directional antennas and multiple omnidirectional antennas constitute an antenna group. At least one switching switch is connected between the at least one radio frequency transceiver and the antenna group. The processor is connected to the at least one switching switch and is configured to control the at least one switching switch to select at least one radio frequency transceiver for connection to at least one antenna in the antenna group. In this way, by switching through the at least one switching switch, a smaller number of radio frequency transceivers can be used to achieve signal transmission and reception for a larger number of antennas, thereby reducing the structural complexity and cost of the radio frequency transceiver system.

[0036] In a possible implementation of the first aspect, at least one radio frequency transceiver includes a first radio frequency transceiver, a second radio frequency transceiver, a third radio frequency transceiver, and a fourth radio frequency transceiver. The plurality of directional antennas includes a first directional antenna, a second directional antenna, and a third directional antenna, each of which includes two antenna elements with orthogonal polarization directions. The plurality of omnidirectional antennas includes a first omnidirectional antenna, a second omnidirectional antenna, a third omnidirectional antenna, and a fourth omnidirectional antenna. The first radio frequency transceiver is connected to the first omnidirectional antenna, and the second radio frequency transceiver is connected to the second omnidirectional antenna. At least one switch includes a first switch and a second switch. The first switch is connected between the third radio frequency transceiver and the third omnidirectional antenna, one antenna element of the first directional antenna, one antenna element of the second directional antenna, and one antenna element of the third directional antenna. The processor is configured to control the first switch to select the connection of the third radio frequency transceiver to one of the third omnidirectional antenna, one antenna element of the first directional antenna, one antenna element of the second directional antenna, and one antenna element of the third directional antenna. The second switching switch is connected between the fourth RF transceiver and the fourth omnidirectional antenna, another antenna unit of the first directional antenna, another antenna unit of the second directional antenna, and another antenna unit of the third directional antenna. The processor is connected to the second switching switch, and the processor is used to control the second switching switch to select the fourth RF transceiver to be connected to one of the fourth omnidirectional antenna, the other antenna unit of the first directional antenna, the other antenna unit of the second directional antenna, and the other antenna unit of the third directional antenna. This structure is simple, and the two omnidirectional antennas are always on, which can meet the access needs of ordinary users. At the same time, the switching switch can simplify the structural complexity and cost of the RF transceiver system.

[0037] In a possible implementation of the first aspect, the processor includes two general purpose I / O ports (GPIO), namely GPIO1 and GPIO2. The processor outputs a high level or a low level through GPIO1 and GPIO2 respectively to control the first switching switch to select the third RF transceiver to be connected to the third omnidirectional antenna, the first antenna unit, the third antenna unit, and the fifth antenna unit. The processor may further include GPIO3 and GPIO4. The processor outputs a high level or a low level through GPIO3 and GPIO4 respectively to control the second switching switch to select the fourth RF transceiver to be connected to the fourth omnidirectional antenna, the second antenna unit, the fourth antenna unit, and the sixth antenna unit. The specific control method is similar to the control method of the aforementioned first switching switch and will not be repeated here.

[0038] It should be noted that the processor uses multiple GPIOs (including GPIO1, GPIO2, GPIO3, and GPIO4) to output parallel signals, thereby implementing switching control between multiple antenna combinations with the help of parallel signals. This control method has the characteristics of clear logic. In some other embodiments, the processor may also use a smaller number of GPIOs (such as one GPIO) to output serial signals. On this basis, at least one serial-to-parallel signal converter is required to be connected in series between the smaller number of GPIOs and the at least one switch to convert the serial signal into a parallel signal, thereby further implementing switching control between multiple antenna combinations with the help of the parallel signal. In this way, the processor can reserve a smaller number of GPIOs for at least one switch, which can save costs and achieve reasonable allocation and full utilization of the GPIOs on the processor.

[0039] In a second aspect, a communication system is provided, which includes a wireless access device and a user equipment as described in any of the above technical solutions, wherein the wireless access device is configured to provide wireless access services to the user equipment.

[0040] Since the communication system provided in the embodiment of the present application includes the wireless access device described in any of the above technical solutions, both can solve the same technical problem and achieve the same effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0086] The following mainly introduces the wireless access device 10.

[0087] Please refer to Figure 2, which is a schematic diagram of the structure of a wireless access device 10 provided in some embodiments of the present application. This embodiment and the following embodiments are illustrative examples using the wireless access device 10 as a router, which should not be considered a special limitation of the present application. The wireless access device 10 is roughly prism-shaped. On this basis, to facilitate the description of the following embodiments, an XYZ coordinate system is established, defining the height direction of the wireless access device 10 as the Z-axis direction. Specifically, the upward direction along the height direction is the +Z-axis direction, the downward direction along the height direction is the -Z-axis direction, and the plane perpendicular to the height direction is the XY plane. It is understood that the coordinate system setting of the wireless access device 10 can be flexibly configured according to actual needs and is not specifically limited here. In other embodiments, the wireless access device 10 may also be roughly cylindrical, prism-shaped, polygonal-shaped, flat, spherical, etc.

[0088] Please refer to FIG2 and FIG3 together. FIG3 is an exploded view of the wireless access device 10 shown in FIG2. The wireless access device 10 includes a housing 11 and an antenna assembly 12.

[0089] The housing 11 is used to protect the internal antenna assembly 12 and other electronic components. The material of the housing 11 includes, but is not limited to, plastic. In some embodiments, the housing 11 includes a lower housing 111 and an upper housing 112. The lower housing 111 includes a base plate 111a and a first side frame 111b. The first side frame 111b is disposed around the base plate 111a and, together with the base plate 111a, defines a first storage space S1. The upper housing 112 includes a cover plate 112a and a second side frame 112b. The second side frame 112b is disposed around the cover plate 112a and, together with the cover plate 112a, defines a second storage space S2. An end D1 of the first side frame 111b away from the base plate 111a is fixedly connected to an end D2 of the second side frame 112b away from the cover plate 112a. The fixing method includes, but is not limited to, threading, snapping, riveting, and bonding, so that the first storage space S1 and the second storage space S2 are connected to form the internal storage space of the housing 11.

[0090] In some embodiments, the lower shell 111 is an opaque shell, and the upper shell 112 is a transparent shell. In this way, the stationary components inside the shell 11 can be placed in the first storage space S1 of the lower shell 111 to ensure a neat appearance, and the moving components inside the shell 11 can be placed in the second storage space S2 of the upper shell 112 to facilitate the user to check whether the device is operating normally. Among them, the stationary components refer to the components of the device that are stationary relative to the shell 11 during operation, that is, the stationary components are relatively fixed to the shell 11. The moving components refer to the components of the device that can move relative to the shell 11 during operation.

[0091] In other embodiments, the lower housing 111 and the upper housing 112 may both be opaque or transparent, or the lower housing 111 may be transparent and the upper housing 112 may be opaque. Furthermore, in other embodiments, the housing 11 may be integrally formed, with the lower housing 111 and the upper housing 112 forming a single structural unit. Alternatively, in other embodiments, the wireless access device 10 may not include the housing 11.

[0092] The antenna assembly 12 is disposed within the housing 11. In some embodiments, the antenna assembly 12 is used to transmit and receive Wi-Fi signals. Specifically, the antenna assembly 12 is used to transmit and receive at least one of WiFi-2.4G, WiFi-5G, WiFi-6E, or signals in the common frequency bands above.

[0093] In some embodiments, to provide wireless access device 10 with high gain characteristics to cover medium- and long-range devices and high-speed devices, antenna assembly 12 includes a directional antenna 121. Refer to Figure 4, which shows the directional pattern of directional antenna 121 in three-dimensional space, according to some embodiments of the present application. The beam of directional antenna 121 has particularly strong signal transmission capabilities in a certain direction, while its signal transmission capabilities in other directions are relatively weak or zero. Therefore, the beam of directional antenna 121 is directional. To facilitate the description of the various embodiments below, the direction in which the beam of directional antenna 121 has the strongest signal transmission capability is hereinafter referred to as the beam orientation of directional antenna 121. In terms of beam orientation, directional antenna 121 has a high gain (8dBi to 12dBi) and excellent anti-interference capabilities, meeting the requirements of high-speed devices. It also has a long coverage range, capable of covering medium- and long-range devices. However, due to the directional beam of directional antenna 121, it is difficult for directional antenna 121 to achieve full coverage, and the initial placement of directional antenna 121 may not be the optimal angle for achieving full coverage of the entire house.

[0094] In order to increase the coverage range of the directional antenna 121, the directional antenna 121 can be physically driven to rotate so that the beam of the directional antenna 121 switches between multiple sectors. However, considering the limitations of factors such as load, inertia, and noise, the physical drive rotation is generally slow (in seconds), which will cause lag in the UE following the scene, slow response speed, and poor user experience. At the same time, the rotation angle of the directional antenna 121 is large, and the torsion angle of the connected feeder cable is large, which will cause winding, knotting, and even wear, thereby affecting the operational stability and service life of the equipment.

[0095] In order to avoid the above problems, multiple fixed-position directional antennas 121 can also be used to serve multiple sectors respectively, so as to achieve coverage of multiple sectors through electrical switching. However, this solution may not be able to provide services for edge user devices in the sector, and the number of directional antennas 121 set up is large, which increases the cost.

[0096] In the embodiment of the present application, in order to simultaneously meet the requirements of high gain, wide coverage, high-speed response, and excellent operational stability, please refer to Figure 5A, which is an exploded view of the antenna assembly 12 in the wireless access device 10 shown in Figure 3. The antenna assembly 12 includes multiple directional antennas 121 and a driving device 122.

[0097] Here, "multiple" means two or more, and the number of directional antennas 121 can be two, three, four, five, and so on. For example, referring to FIG5A , the number of directional antennas 121 is three. The multiple directional antennas 121 are distributed along a circular array. On this basis, in order to facilitate the description of the embodiments below, the central axis of the circular array of the multiple directional antennas 121 is defined as the first axis O1, and the first axis O1 passes through the center of the circular array of the multiple directional antennas 121 and is perpendicular to the plane in which the circular array is located. In some embodiments, referring to FIG5A , the first axis O1 is parallel to the +Z axis direction and the -Z axis direction. In some other embodiments, the first axis O1 may also be parallel to the X axis direction, or parallel to the Y axis direction, which is not specifically limited here.

[0098] In some embodiments, please refer to Figure 6, which is a beam pattern of multiple directional antennas 121 in the antenna assembly 12 shown in Figure 5A. Each directional antenna 121 radiates signals in a direction away from the first axis O1. The beam directions of the three directional antennas 121 are A, B, and C respectively. The beam directions A, B, and C are all pointing in a direction away from the first axis O1. Specifically, the beam directions of the multiple directional antennas 121 can be parallel to the XY plane, or can be tilted at a certain angle relative to the XY plane in the +Z axis direction or the -Z axis direction. This embodiment and the following embodiments are exemplified by the beam directions of the multiple directional antennas 121 being parallel to the XY plane.

[0099] The beams of the multiple directional antennas 121 are respectively located within multiple sectors F, where sector F refers to a sector-shaped area with an infinite radius. Please refer to Figure 7, which is a schematic diagram of the relative positions of the beams of the multiple directional antennas 121 and the multiple sectors F in the antenna assembly 12 shown in Figure 5A. The beam of the directional antenna 121 is located within the sector F, which means that at least the portion of the beam of the directional antenna 12 with the strongest signal transmission capability is located within the sector F. The multiple sectors F are arranged around the first axis O1, and the vertices of the multiple sectors F are located on the first axis O1. The vertex of the sector F refers to the intersection between the two radial sides of the sector area, that is, the center point of the circle corresponding to the sector area.

[0100] In the embodiments of the present application, the beam of a directional antenna 121 may be located within one or more sectors F, or the beams of multiple directional antennas 121 may be located within one sector F. The following embodiments are exemplified by the case where the beam of a directional antenna 121 is located within one sector F. In other words, the number of sectors F is equal to the number of directional antennas 121, and there is a one-to-one correspondence between the sectors F and the directional antennas 121. The beam of each directional antenna 121 is located within a corresponding sector F. For example, referring to FIG7 , the number of sectors F and the number of directional antennas 121 are both three. The three directional antennas 121 correspond one-to-one to the three sectors F, and the beam of each directional antenna 121 is located within a corresponding sector F.

[0101] The central angles of multiple sectors F can be equal or unequal. The following embodiments are illustrative examples assuming that the central angles of multiple sectors F are equal. In some embodiments, assume that the number of sectors F is N, where N is a positive integer greater than 1, and the central angle of each sector F is 360° / N. For example, referring to FIG. 7 , the number of sectors F is 3, where 3 is a positive integer greater than 1, and the central angle of each sector F is 120°. This facilitates the rotation drive control described below.

[0102] In some embodiments, two adjacent sectors F in a plurality of sectors F may or may not overlap. In some embodiments, referring to FIG. 7 , the plurality of sectors F are connected end to end along the circumference of the first axis O1. That is, one radial edge of two adjacent sectors F overlaps, and the remaining areas other than the radial edge do not overlap. For example, referring to FIG. 7 , two adjacent sectors in the plurality of sectors F are a first sector F1 and a second sector F2. The first sector F1 has a first radial edge a1, and the second sector F2 has a second radial edge a2. The first radial edge a1 overlaps the second radial edge a2, and the remaining areas of the first sector F1 other than the first radial edge a1 do not overlap with the remaining areas of the second sector F2 other than the second radial edge a2. In this way, the plurality of sectors F cover a 360° range around the first axis O1, providing a wide coverage area. Furthermore, the likelihood of two adjacent directional antennas 121 covering the same target user is low, facilitating the rational allocation of resources.

[0103] Referring back to FIG. 5A , the driving device 122 is configured to drive the plurality of directional antennas 121 to rotate relative to the housing 11 to adjust the beam directions of the plurality of directional antennas 121 within the plurality of sectors F. In some embodiments, the driving device 122 is configured to drive the plurality of directional antennas 121 to rotate relative to the housing 11 within the XY plane to adjust the beam directions of the plurality of directional antennas 121 within the plurality of sectors F. This enables the wireless access device 10 to provide coverage to the target user equipment.

[0104] In this way, the directional antenna 121 has high gain characteristics and can support single-user / mesh network signal enhancement. Furthermore, the beams of multiple directional antennas 121 are located in multiple sectors F. The driving device 122 drives the multiple directional antennas 121 to rotate within the multiple sectors F, switching the beam directions of the multiple directional antennas 121. This increases the coverage range of the directional antennas 121 and improves coverage in edge blind spots. While maintaining the same coverage range, compared to an electrical switching approach, the number of directional antennas 121 can be reduced, saving costs. Furthermore, driving the multiple directional antennas 121 to rotate within their respective sectors F reduces the rotation angle of the directional antennas 121. This, on the one hand, reduces lag, improves response speed, and enhances user experience in UE-following scenarios. On the other hand, the smaller rotation angle of the directional antennas 121 reduces the risk of feeder cable tangling, kinking, and wear, thereby improving device operational stability. Therefore, compared to the prior art, the wireless access device 10 provided in this embodiment of the present application simultaneously features high gain, wide coverage, high-speed response, and superior operational stability.

[0105] In the above embodiment, the manner in which the driving device 122 drives the plurality of directional antennas 121 to rotate includes but is not limited to synchronous driving and asynchronous driving.

[0106] In some embodiments, referring back to Figures 3 and 5A , the antenna assembly 12 further includes a first bracket 123. The material of the first bracket 123 includes, but is not limited to, plastic. Multiple directional antennas 121 are secured to the first bracket 123. Methods for securing the multiple directional antennas 121 to the first bracket 123 include, but are not limited to, bonding, snapping, and threading. Alternatively, the multiple directional antennas 121 may be directly molded onto the first bracket 123.

[0107] Based on the above, the drive device 122 includes a drive member 1221, which is a rotating drive member. Specifically, the drive member 1221 can be a rotary motor, or a combination of a rotary motor and a reducer. Types of rotary motors include, but are not limited to, servo motors, stepper motors, torque motors, switched reluctance motors, and brushless DC motors. The drive member 1221 is connected to the first bracket 123 and is used to drive the first bracket 123 to rotate about an axis. The axis of rotation of the first bracket 123 driven by the drive member 1221 is collinear with the first axis O1, thereby driving the multiple directional antennas 121 to rotate synchronously, thereby adjusting the beam pointing of the multiple directional antennas 121 within multiple sectors F.

[0108] This driving mode is a synchronous driving mode. In this driving mode, the rotation axes of the multiple directional antennas 121 and their beams are all the first axis O1, and in the process of adjusting the beam pointing of the multiple directional antennas 121 so that the wireless access device 10 covers the target user equipment, the rotation directions and rotation angles of the multiple directional antennas 121 and their beams are the same.

[0109] For example, please refer to Figure 8, which is a schematic diagram of the beam pointing of the three directional antennas 121 in the antenna assembly 12 shown in Figure 5A. The current beam pointing directions of the three directional antennas 121 are A1, B1, and C1, respectively. Driven by the driving device 122, when the beam pointing to A1 rotates to point to A2, the beam pointing to B1 synchronously rotates to point to B2, and the beam pointing to C1 synchronously rotates to point to C2; when the beam pointing to A1 rotates to point to A3, the beam pointing to B1 synchronously rotates to point to B3, and the beam pointing to C1 synchronously rotates to point to C3. The beam rotation directions and rotation angles of these three directional antennas 121 are the same.

[0110] This drive mode is a synchronous drive mode. The drive device 122 has a simple structure, low cost, and low assembly difficulty, which helps reduce the cost and assembly difficulty of the wireless access device 10. It can improve the edge coverage performance of single-user devices or the coverage performance of some multi-user devices.

[0111] Based on the above, to support the drive device 122 and first bracket 123 in the above embodiment, referring back to Figure 5A , the antenna assembly 12 also includes a second bracket 124. The material of the second bracket 124 includes, but is not limited to, plastic. The second bracket 124 can have various structural forms, including, but not limited to, block, frame, plate, and the like. The second bracket 124 is fixed within the housing 11. Methods for securing the second bracket 124 to the housing 11 include, but are not limited to, threaded connections, clip connections, riveting, and adhesive bonding.

[0112] In some embodiments, please continue to refer to Figure 5A and refer to Figure 3 in combination. The second bracket 124 includes a support plate 124a and a plurality of support columns 124b. The support plate 124a is opposite to the bottom plate 111a of the housing 11 and is spaced apart. The plurality of support columns 124b are arranged between the support plate 124a and the bottom plate 111a, and one end of the plurality of support columns 124b is fixed to the support plate 124a and the other end is fixed to the bottom plate 111a. In some embodiments, the plurality of support columns 124b are integrally formed with the support plate 124a, and the plurality of support columns 124b are fixedly connected to the bottom plate 111a by bonding, threading, clamping, riveting, etc. The plurality of support columns 124b are evenly arranged around the edge of the support plate 124a. The number of support columns 124b can be two, three, four, five, etc. In this embodiment, the number of support columns 124b is four for illustrative purposes.

[0113] In this way, the second bracket 124 is fixed on the bottom plate 111 a of the housing 11 . This structure is simple, and facilitates the installation of the second bracket 124 in the housing 11 . It also uses less material and has a lower cost.

[0114] Based on the above embodiment, the first bracket 123 is rotatably connected to the second bracket 124 about an axis. Specifically, the first bracket 123 is rotatably connected to the support plate 124a of the second bracket 124, for example, by a rotating shaft. The rotation axis of the first bracket 123 relative to the support plate 124a is colinear with the first axis O1. This allows the second bracket 124 to support the first bracket 123, facilitating installation and removal.

[0115] In the above embodiment, please refer to FIG5B , which is a cross-sectional view of the antenna assembly 12 within the electronic device 10 shown in FIG3 . The driving member 1221 of the driving device 122 is disposed on a side of the support plate 124a away from the first bracket 123 . The stator (which may be a housing) of the driving member 1221 may be fixed to the support plate 124a , and the rotor (which may be an output shaft) of the driving member 1221 may pass through the support plate 124a and be fixed to the first bracket 123 . In this way, the driving device 122 is supported by the second bracket 124 , resulting in a simple structure that facilitates installation and removal operations.

[0116] It should be noted that the second bracket 124 is not limited to the above-mentioned structure, and may also be a structure of any other shape as long as it can support the driving device 122 and the first bracket 123 , which will not be elaborated here.

[0117] Based on the above embodiments, to provide signals to the multiple directional antennas 121 and the driving device 122, in some embodiments, as further described in FIG5A , the antenna assembly 12 further includes a circuit board assembly 125. The circuit board assembly 125 includes a circuit board and electronic components disposed thereon, including but not limited to chips. The circuit board assembly 125 may include a single circuit board and electronic components disposed thereon, or may include multiple circuit boards and electronic components disposed thereon, without specific limitation herein.

[0118] In some embodiments, please refer to Figures 3 and 5A together. The circuit board assembly 125 is arranged on the side of the support plate 124a away from the first bracket 123. The circuit board assembly 125 is also located on the side of the support plate 124a away from the multiple directional antennas 121. In some embodiments. The circuit board assembly 125 is relatively fixed to the housing 11. Specifically, the circuit board assembly 125 is fixed on the bottom plate 111a and is located between the multiple support columns 124b. In this way, the circuit board assembly 125 can be accommodated in the space surrounded by the multiple support columns 124b, which can achieve effective use of space. Of course, the circuit board assembly 125 can also be set at other locations, which is not specifically limited here.

[0119] Based on the above, please continue to refer to FIG. 5A and FIG. 5B , the antenna assembly 12 further includes a plurality of feed lines 126 and drive cables 127 .

[0120] The feeder lines 126 may be coaxial lines, and multiple feeder lines 126 are connected between the multiple directional antennas 121 and the circuit board assembly 125, respectively, to transmit the radio frequency signals generated by the circuit board assembly 125 to the multiple directional antennas 121 for signal transmission. At the same time, the signals received by the multiple directional antennas 121 can also be transmitted to the circuit board assembly 125 via the multiple feeder lines 126 to facilitate demodulation of the received signals.

[0121] In addition, the driving cable 127 is connected between the driving member 1221 and the circuit board assembly 125 to transmit the driving signal generated by the circuit board assembly 125 to the driving member 1221 to drive the driving member 1221.

[0122] Based on the above embodiment, due to the positional constraints of the connected components, multiple feeder wires 126 need to span the support plate 124a. Furthermore, to facilitate wiring and maintain a neat appearance, in some embodiments (particularly referring to FIG. 5B ), the support plate 124a is provided with at least one wire trough 128, where "at least one" means one or more, and the multiple feeder wires 126 are routed through this at least one wire trough 128. This allows the multiple feeder wires 126 to be routed through the support plate 124a, facilitating wiring while maintaining a neat appearance.

[0123] In some embodiments, please refer to FIG9 , which is a top view of the second bracket 124 in the antenna assembly 12 shown in FIG5A and FIG5B . There are multiple wire slots 128, and the multiple wire slots 128 are distributed along a circular array. The central axis of the circular array of the multiple wire slots 128 is the second axis O2. The second axis O2 is colinear with the first axis O1. Each wire slot 128 is provided with at least one feeder line 126. In this way, by separating the multiple feeder lines 126 with the help of the multiple wire slots 128, the multiple feeder lines 126 can be prevented from being entangled or tangled. For example, please refer to FIG9 , there are two wire slots 128.

[0124] Since the directional antenna 121 rotates relative to the circuit board assembly 125 under the drive of the driving device 122 during the operation of the antenna assembly 12, the feed line 126 connected between the directional antenna 121 and the circuit board assembly 125 will swing as the directional antenna 121 rotates. Based on this, in order to avoid the problem of the feed line 126 getting stuck or wearing out in the wire groove 128, please continue to refer to Figure 9. The wire groove 128 can be a long groove, which is an arc-shaped long groove extending around the second axis O2, and the second axis O2 is the center line of the arc-shaped long groove. In this way, the feed line 126 can slide along the wire groove 128 during the swinging process, thereby reducing the risk of the feed line 126 getting stuck and wearing out in the wire groove 128. In some embodiments, the width of the wire groove 128 can be 3 millimeters (mm)-8 mm. For example, the width of the wire groove 128 can be 5 mm.

[0125] On the basis of the above, optionally, please refer back to Figure 5B. Each wire trough 128 is provided with a wire sleeve 132, which is fixed on the first bracket 123. At least one feeder wire 126 passing through the wire trough 128 is accommodated in the wire sleeve 132, and the wire sleeve 132 and the feeder wire 126 passing therethrough are as a whole, sliding in the wire trough 128, which can minimize the risk of the feeder wire 126 being stuck and worn in the wire trough 128.

[0126] It should be noted that since the support plate 124a is also used to support the above-mentioned driving member 1221, please refer to Figure 5B and Figure 9 for details. The support plate 124a includes a first area Q1 and a second area Q2. The first area Q1 is surrounded by a plurality of wire grooves 128. The first area Q1 is used to fix the stator of the driving member 1221 to support the driving member 1221. The second area Q2 is located on the side of the plurality of wire grooves 128 away from the first area Q1 and surrounds the plurality of wire grooves 128. The second area Q2 is connected to the plurality of support columns 124b mentioned above and is connected to the bottom plate 111a with the help of the plurality of support columns 124b.

[0127] On the basis of the above, in order to ensure the support strength of the first area Q1 for the driving member 1221, a certain gap width should be reserved between two adjacent wire grooves 128. Specifically, the support plate 124a also includes a connection area Q3, which is connected between the first area Q1 and the second area Q2, and in the direction around the second axis O2, the connection area Q3 is located between two adjacent wire grooves 128. The connection area Q3 needs to meet a certain width to stably connect the first area Q1 to the second area Q2, thereby ensuring the support strength of the first area Q1 for the driving member 1221. However, in this way, the sum of the central angles of the multiple wire grooves 128 is small, less than 360°, and the sum of the sliding angles of the multiple feeder wires 126 in the multiple wire grooves 128 is also small. The swing flexibility of the multiple feeder wires 126 is limited, and there is a risk of wire jamming and wear of the feeder wires 126 during the swinging process.

[0128] In order to solve the above problems, in some embodiments, please refer to Figure 10, which is a top view of the second bracket 124 provided in some other embodiments of the present application. In this embodiment, the multiple wire grooves 128 are distributed in a centrally symmetrical manner relative to the second axis O2. On this basis, the multiple wire grooves 128 are also long grooves, which have a first end N1 and a second end N2 relative to each other. From the first end N1 to the second end N2, the long groove extends around the second axis O2, and the distance from the first end N1 to the second axis O2 (specifically, the vertical distance) is not equal to the distance from the second end N2 to the second axis O2 (specifically, the vertical distance). In some embodiments, please refer to Figure 10, the distance from the first end N1 to the second axis O2 is less than the distance from the second end N2 to the second axis O2. In some other embodiments, the distance from the first end N1 to the second axis O2 may also be greater than the distance from the second end N2 to the second axis O2, which is not specifically limited here.

[0129] The elongated groove extending about the second axis O2 means that the central angle θ of the elongated groove relative to the second axis O2 is greater than 0°. Specifically, the central angle θ of the elongated groove relative to the second axis O2 is the angle between a perpendicular line L1 extending from the first end N1 of the elongated groove to the second axis O2 and a perpendicular line L2 extending from the second end N2 of the elongated groove to the second axis O2.

[0130] On the basis of the above, each wire trough 128 is provided with at least one feeder wire 126 , and the at least one feeder wire 126 can slide along the wire trough 128 .

[0131] In this way, in the direction around the second axis O2, of the two adjacent wire grooves 128, the second end N2 of one wire groove 128 is located on the side of the first end N1 of the other wire groove 128 that is away from the second axis O2 or closer to the second axis O2. Specifically, when the distance from the first end N1 to the second axis O2 is less than the distance from the second end N2 to the second axis O2, refer to Figure 10. Of the two adjacent wire grooves 128, the second end N2 of one wire groove 128 is located on the side of the first end N1 of the other wire groove 128 that is away from the second axis O2. When the distance from the first end N1 to the second axis O2 is greater than the distance from the second end N2 to the second axis O2, of the two adjacent wire grooves 128, the second end N2 of one wire groove 128 is located on the side of the first end N1 of the other wire groove 128 that is closer to the second axis O2. In this way, the two adjacent wire grooves 128 are staggered. This increases the central angle of the wire trough 128 relative to the second axis O2, improving the swinging flexibility of the feeder 126 and reducing the risks of winding, tangling, and wear. Furthermore, it ensures that a certain width of connecting area Q3 exists between two adjacent wire troughs 128, stably connecting the first area Q1 to the second area Q2, thereby ensuring the first area Q1's stable support for the driver 1221.

[0132] In the above embodiment, the path extending from the first end N1 to the second end N2 of the wire trough 128 can be a straight line or an arc, and the arc can be curved in a direction away from the second axis O2 or in a direction toward the second axis O2. In the embodiment shown in Figure 10, the path extending from the first end N1 to the second end N2 of the wire trough 128 is an arc, and the arc is curved in a direction away from the second axis O2. This ensures that the feeder 126 slides smoothly along the wire trough 128, reducing wear.

[0133] Please refer to Figure 11, which is a top view of the second bracket 124 provided in some embodiments of the present application. In this embodiment, the plurality of wire grooves 128 extend from the first end N1 to the second end N2 in a straight line. This results in a regular shape for the wire grooves 128, making them easier to manufacture.

[0134] Please refer to Figure 12, which is a top view of a second bracket 124 provided in yet another embodiment of the present application. In this embodiment, a plurality of wire grooves 128 extend from the first end N1 to the second end N2 in an arc-like path, with the arcs extending in a direction toward the second axis O2. The regular shape of these wire grooves 128 facilitates machining.

[0135] It should be noted that the extension path of the wire groove 128 from the first end N1 to the second end N2 can also be other shapes, as long as it can meet the requirements of extending from the first end N1 to the second end N2 around the second axis O2, and the distance from the first end N1 to the second axis O2 is not equal to the distance from the second end N2 to the second axis O2. They will not be listed one by one here.

[0136] In some embodiments, assuming that the number of the wire grooves 128 is M, where M is a positive integer greater than 1, a central angle θ of each wire groove 128 relative to the second axis O2 is greater than or equal to (360 / M)°.

[0137] Specifically, the number of wire slots 128 can be two, three, four, and so on. The greater the number of wire slots 128, the lower the structural strength of the support plate 124a. The fewer the number of wire slots 128, the greater the possibility of the feeder line 126 becoming tangled or knotted. Based on this, in some embodiments, the number of wire slots 128 can be equal to the number of directional antennas 121, with multiple wire slots 128 corresponding to multiple directional antennas 121, and the feeder line 126 connected to the directional antenna 121 is passed through the wire slot 128 corresponding to the directional antenna 121. In this way, the number of wire slots 128 is moderate, which can simultaneously take into account the structural strength of the support plate 124a and the possibility of the feeder line 126 becoming tangled or knotted.

[0138] For example, referring to Figures 10, 11, or 12, there are also three wire slots 128. The feed lines 126 of the three directional antennas 121 are respectively routed through the three wire slots 128. Furthermore, the central angle θ of each of the three wire slots 128 relative to the second axis O2 is greater than or equal to 120°.

[0139] In this way, the sum of the central angles θ of the plurality of wire slots 128 relative to the second axis O2 is greater than or equal to 360°, which can ensure the swing flexibility of the feeder line 126 as much as possible and reduce the risk of wire jamming and wear.

[0140] Please refer back to Figure 5A. The antenna assembly 12 may also include an omnidirectional antenna 129. Please refer to Figure 13, which is a directional diagram of the omnidirectional antenna 129 in three-dimensional space provided in some embodiments of the present application. The beam of the omnidirectional antenna 129 is approximately "apple" shaped, that is, the omnidirectional antenna 129 exhibits 360° uniform radiation in a plane perpendicular to the central axis of the beam, which can achieve short-range coverage within the 360° range of the plane and can meet the access needs of ordinary users. In some embodiments, the central axis of the beam of the omnidirectional antenna 129 is collinear with the first axis O1. In some other embodiments, the central axis of the beam of the omnidirectional antenna 129 may also intersect with or be perpendicular to the first axis O1, which is not specifically limited here.

[0141] In some embodiments, the omnidirectional antenna 129 is fixed relative to the housing 11. Specifically, in some embodiments, referring back to Figure 5A , the omnidirectional antenna 129 is mounted on the support column 124b of the second bracket 124. This allows the omnidirectional antenna 129 to be supported by the support column 124b, eliminating the need for a separate support structure. This reduces the structural complexity of the antenna assembly 12 and eases assembly difficulty.

[0142] The number of omnidirectional antennas 129 can be one or more. In some embodiments, referring to Figure 5A , there are multiple omnidirectional antennas 129, each of which is disposed on a plurality of support posts 124b. For example, referring to Figure 5A , there are four omnidirectional antennas 129, each corresponding to one of the four support posts 124b. Each omnidirectional antenna 129 is disposed on the support post 124b corresponding to the omnidirectional antenna 129. In this way, the multiple omnidirectional antennas 129 can support the transmission and reception of multiple different channel signals, thereby increasing the versatility of application of the wireless access device 10.

[0143] Based on the above embodiment, please continue to refer to FIG. 5A , the circuit board assembly 125 is further connected to the multiple omnidirectional antennas 129 to provide radio frequency signals to the multiple omnidirectional antennas 129 and demodulate the signals received by the multiple omnidirectional antennas 129 .

[0144] As can be seen from the above, the circuit board assembly 125 is used to provide radio frequency (RF) signals to the multiple directional antennas 121 and the multiple omnidirectional antennas 129. For details, please refer to Figure 14, which is a circuit diagram of the antenna assembly 12 shown in Figure 5A. In the antenna assembly 12, the circuit board assembly 125 includes a processor 1251 and a radio frequency transceiver system 1252.

[0145] The processor 1251 may include one or more processing units, for example, the processor 1251 may include an application processor (AP), a modem processor, a graphics processing unit (GPU), an image signal processor (ISP), a controller, a video codec, a digital signal processor (DSP), a baseband processor, and / or a neural-network processing unit (NPU). Different processing units may be independent devices or integrated into one or more processors.

[0146] Processor 1251 is used to generate transmit signals or process receive signals. RF transceiver system 1252 is used to receive transmit signals generated by processor 1251, modulate the transmit signals to generate RF signals, and output the RF signals to antenna assembly 130 for signal transmission. RF transceiver system 1252 is also used to receive RF signals from antenna assembly 130, demodulate the RF signals to generate receive signals, and transmit the receive signals to processor 1251 for signal reception. Antenna assembly 130 is composed of the aforementioned multiple directional antennas 121 and multiple omnidirectional antennas 129.

[0147] To enable RF transceiver system 1252 to provide different signals to multiple antennas in antenna group 130, RF transceiver system 1252 may be a multiple-input, multiple-output (MIMO) system. In some embodiments, RF transceiver system 1252 includes multiple RF transceivers (also referred to as RF transceiver chains or TRx). The number of these multiple RF transceivers is equal to and corresponds to the number of antennas in antenna group 130 (i.e., the sum of the number of directional antennas 121 and the number of omnidirectional antennas 129). Each RF transceiver is used to transmit and receive signals for the corresponding antenna. However, this results in a large number of RF transceivers within RF transceiver system 1252, resulting in a more complex structure and higher cost.

[0148] To reduce the structural complexity and cost of the circuit board assembly 125, in some embodiments, the RF transceiver system 1252 includes at least one RF transceiver, the number of which is less than the number of antennas in the antenna group 130. With reference to FIG14 , the circuit board assembly 125 also includes at least one switch 1253. The at least one switch 1253 is connected between the at least one RF transceiver and the antenna group 130. Based on this, the processor 1251 can also generate an operation control signal based on the instruction opcode and timing signal to control instruction fetching and execution. Specifically, the processor 1251 is also connected to the at least one switch 1253, and the processor 1251 is configured to control the at least one switch 1253 to select at least one RF transceiver for connection to at least one antenna in the antenna group 130.

[0149] In this way, by switching through at least one switch 1253, a smaller number of RF transceivers can be used to achieve signal transmission and reception of a larger number of antennas, which can reduce the structural complexity and cost of the RF transceiver system 1252.

[0150] In some embodiments, please refer to Figure 15 , which illustrates a schematic diagram of the connection structure of the processor 1251, the RF transceiver system 1252, at least one switch 1253, and the antenna array 130 in the wireless access device 10 shown in Figure 14 . In this embodiment, the RF transceiver system 1252 is a MIMO system, specifically a 4x4 MIMO system, i.e., a system with four outputs and four inputs. Furthermore, the RF transceiver system 1252 may include four RF transceivers, each configured to implement one output and one input. The four transceivers are a first RF transceiver RF1, a second RF transceiver RF2, a third RF transceiver RF3, and a fourth RF transceiver RF4.

[0151] In some embodiments, the four RF transceivers can be used to generate signals of different channels. Thus, the antenna assembly 12 can transmit and receive signals of four different channels. In other embodiments, the four RF signals generated by the four RF transceivers can be signals of the same channel, or two or three of the RF transceivers can generate signals of the same channel.

[0152] The number of the plurality of directional antennas 121 is three, specifically including a first directional antenna 121a, a second directional antenna 121b and a third directional antenna 121c. The first directional antenna 121a, the second directional antenna 121b and the third directional antenna 121c each include two antenna units with orthogonal polarization directions. Specifically, the first directional antenna 121a includes a first antenna unit Ant d1 and the second antenna unit Ant d2 The second directional antenna 121b includes a third antenna unit Ant d3 and the fourth antenna unit Ant d4 The third directional antenna 121c includes a fifth antenna unit Ant d5 and the sixth antenna unit Ant d6 .

[0153] The number of the plurality of omnidirectional antennas 129 is four, specifically including a first omnidirectional antenna Ant 01 , the second omnidirectional antenna Ant 02 、Third omnidirectional antenna Ant 03 and the fourth omnidirectional antenna Ant 04 .

[0154] On the basis of the above, the first radio frequency transceiver RF1 and the first omnidirectional antenna Ant 01 Connect the second RF transceiver RF2 to the second omnidirectional antenna Ant 02 connect.

[0155] The at least one switch is two, specifically including a first switch 1253a and a second switch 1253b. The first switch 1253a and the second switch 1253b can be single-pole multi-throw switches, specifically single-pole four-throw (SP4T) switches.

[0156] The first switch 1253a is connected to the third radio frequency transceiver RF3 and the third omnidirectional antenna Ant. 03 , an antenna unit of the first directional antenna 121a (for example, the first antenna unit Ant d1 ), an antenna unit of the second directional antenna 121b (such as the third antenna unit Ant d3 ), an antenna unit of the third directional antenna 121c (such as the fifth antenna unit Ant d5 On this basis, the processor 1251 is connected to the first switch 1253a, and the processor 1251 is used to control the first switch 1253a to select the third radio frequency transceiver RF3 and the third omnidirectional antenna Ant. 03 , first antenna unit Ant d1 , the third antenna unit Ant d3 , the fifth antenna unit Ant d5 A connection in .

[0157] In the above embodiment, the processor 1251 includes two general purpose I / O ports (GPIO), namely GPIO1 and GPIO2. The processor 1251 controls the first switch 1253a to select the third RF transceiver RF3 and the third omnidirectional antenna Ant by outputting a high level or a low level respectively through GPIO1 and GPIO2. 03 , first antenna unit Ant d1 , the third antenna unit Ant d3 , the fifth antenna unit Ant d5 A connection in .

[0158] For example, when both GPIO1 and GPIO2 output high level, the first switch 1253a selects the fifth antenna unit Ant. d5 At this time, the third radio frequency transceiver RF3 will pass the fifth antenna unit Ant d5 When both GPIO1 and GPIO2 are low level, the first switch 1253a switches on the third omnidirectional antenna Ant. 03 At this time, the third radio frequency transceiver RF3 will pass the third omnidirectional antenna Ant 03 When GPIO1 output is high level and GPIO2 output is low level, the first switch 1253a selects the first antenna unit Ant.d1 At this time, the third radio frequency transceiver RF3 will pass the first antenna unit Ant d1 When GPIO1 outputs a low level and GPIO2 outputs a high level, the first switch 1253a switches on the third antenna unit Ant. d3 At this time, the third radio frequency transceiver RF3 will pass the third antenna unit Ant d3 To send and receive data.

[0159] The second switch 1253b is connected to the fourth radio frequency transceiver RF4 and the fourth omnidirectional antenna Ant. 04 , another antenna unit of the first directional antenna 121a (such as the second antenna unit Ant d2 ), another antenna unit of the second directional antenna 121b (such as the fourth antenna unit Ant d4 ), another antenna unit of the third directional antenna 121c (such as the sixth antenna unit Ant d6 On this basis, the processor 1251 is connected to the second switch 1253b, and the processor 1251 is used to control the second switch 1253b to select the fourth radio frequency transceiver RF4 and the fourth omnidirectional antenna Ant. 04 , second antenna unit Ant d2 , the fourth antenna unit Ant d4 , the sixth antenna unit Ant d6 A connection in .

[0160] In the above embodiment, the processor 1251 may further include GPIO3 and GPIO4. The processor 1251 controls the second switch 1253b to select the fourth RF transceiver RF4 and the fourth omnidirectional antenna Ant by outputting a high level or a low level respectively through GPIO3 and GPIO4. 04 , second antenna unit Ant d2 , the fourth antenna unit Ant d4 , the sixth antenna unit Ant d6 The specific control method is similar to the control method of the first switch 1253a, and will not be described in detail here.

[0161] Furthermore, if the processor has a small number of GPIOs, their level states may not be sufficient to cover all switch states. For example, if a manufacturer's product only has one GPIO port, serial signals can be used to control the switch state. Specifically, a serial-to-parallel signal converter can be added to convert the high and low level information carried by the received serial signal into a set of parallel signals that respectively enable multiple switch states, thereby achieving similar functionality to GPIOs 1-04 described above.

[0162] This structure is simple, and two omnidirectional antennas (the first omnidirectional antenna Ant 01 and the second omnidirectional antenna Ant 02 ) is always on, which can meet the access needs of ordinary users. At the same time, the structural complexity and cost of the radio frequency transceiver system 1252 can be simplified by switching the switch.

[0163] Referring back to FIG. 14 , the circuit board assembly 125 further includes a driver 1254 . In some embodiments, the driver 1254 may be a driver chip. The driver 1254 is connected between the processor 1251 and the driver 1221 . The processor 1251 is further configured to control the driver 1254 to drive the driver 1221 .

[0164] The above describes a specific structure of the antenna assembly 12. Referring back to Figure 3 , the multiple directional antennas 121 and the first bracket 123 constitute the moving portion of the antenna assembly 12, housed within the second accommodating cavity S2 of the upper housing 112 of the housing 11. The driver 1221 of the driver 122, the second bracket 124, and the circuit board assembly 125 constitute the stationary portion of the antenna assembly 12, housed within the first accommodating space S1 of the lower housing 111. This allows the lower housing 111 to shield and protect the stationary portion, while the light-transmitting upper housing 112 allows for visualization of the movement of the multiple directional antennas 121 and the first bracket 123, making it easier for users to verify the proper functioning of the device.

[0165] It should be noted that, in addition to the structure described in the above embodiment, the antenna assembly 12 may also have other structural forms.

[0166] Please refer to Figures 16, 17A, and 17B. Figure 16 is a perspective view of an antenna assembly 12 provided in yet other embodiments of the present application. Figure 17A is an exploded view of the antenna assembly 12 shown in Figure 16. Figure 17B is a cross-sectional view of the antenna assembly 12 shown in Figure 16. The antenna assembly 12 shown in Figure 17A conceals a directional antenna 121. The antenna assembly 12 shown in this embodiment differs from the antenna assembly 12 shown in Figures 3 and 5A in that, in this embodiment, the first bracket 123 is fixed relative to the housing 11. In some embodiments, particularly referring to Figure 17B, the first bracket 123 is fixed to the support plate 124a of the second bracket 124. Specifically, the first bracket 123 can be in direct contact with the support plate 124a of the second bracket 124 and secured together by adhesive bonding. Furthermore, multiple directional antennas 121 are rotatably connected to the first bracket 123 about their respective axes. The rotational axes of the multiple directional antennas 121 relative to the first bracket 123 are not collinear with the first axis O1.

[0167] For example, please refer to Figure 17A. The rotatable axes of the three directional antennas 121 relative to the first bracket 123 are the third axis O3, the fourth axis O4 and the fifth axis O5, which are not colinear with the first axis O1.

[0168] Based on the above embodiment, optionally, the rotational axes of the multiple directional antennas 121 relative to the first bracket 123 are parallel to the first axis O1. For example, referring to FIG. 17A , the third axis O3 , the fourth axis O4 , and the fifth axis O5 are parallel to the first axis O1 . This facilitates positioning and driving.

[0169] In other embodiments, the rotational axes of the multiple directional antennas 121 relative to the first bracket 123 may also intersect the first axis O1. The following embodiments are illustrative in that the rotational axes of the multiple directional antennas relative to the first bracket 123 are parallel to the first axis O1, which is not to be considered a special limitation of the present application.

[0170] On the basis of the above, the driving device 122 is used to synchronously drive the multiple directional antennas 121 to rotate around their rotation axes respectively, so as to adjust the beam pointing of the multiple directional antennas 121 in multiple sectors F respectively.

[0171] For example, please refer to Figure 18, which is a schematic diagram illustrating the relative positions of the beams of multiple directional antennas 121 and multiple sectors F in the antenna assembly 12 shown in Figure 16. The driving device 122 is used to synchronously drive the three directional antennas 121 to rotate about the third axis O3, the fourth axis O4, and the fifth axis O5, respectively, to adjust the beam directions of the three directional antennas 121 within the three sectors F. The beams of the three directional antennas 121 are respectively directed toward A, B, and C. During adjustment, the three beams rotate about the third axis O3, the fourth axis O4, and the fifth axis O5 within the three sectors F.

[0172] This synchronous drive method is employed. Because the rotation axes of the multiple directional antennas 121 are not collinear with the first axis O1, the positional accuracy requirements for the multiple directional antennas 121 relative to the first bracket 123, as well as the relative positional accuracy requirements for the multiple directional antennas 121, are lower, simplifying installation. Furthermore, the structure of the drive device 122 can be designed to achieve different angular velocities and / or rotational directions for the multiple directional antennas 121, adapting to the needs of various application scenarios.

[0173] It should be noted that, in this embodiment, since the physical size of the wireless access device 10 is very small relative to the wireless coverage range, when designing the control method of the driving device 122, although in fact the rotation axis of the beam pointing of the multiple directional antennas 121 is not collinear with the center line of the multiple sectors F (that is, the first axis O1), it is also possible to design it according to the collinearity of the rotation axis of the beam pointing of the directional antenna 121 and the center line of the corresponding sector, so as to simplify the control difficulty of the driving device 122.

[0174] Based on the above embodiments, the driving device 122 has various structural forms. In some embodiments, please continue to refer to FIG. 17A , the driving device 122 includes a driving member 1221 , a driving gear 1222 , and a plurality of driven members 1223 .

[0175] Among them, the driving member 1221 is a rotating driving member. Specifically, the driving member 1221 can be a rotating motor, or a combination of a rotating motor and a reducer. The driving member 1221 is connected to the driving gear 1222. In some embodiments, please refer to Figure 17B, the stator of the driving member 1221 (which can be a shell) can be fixed to the support plate 124a of the second bracket 124, and the rotor of the driving member 1221 (which can be an output shaft) can pass through the support plate 124a and the through hole on the first bracket 123, and be fixedly connected to the driving gear 1222. The driving member 1221 is used to drive the driving gear 1222 to rotate.

[0176] The follower 1223 is a gear or a rack extending along an arc. Figures 16 and 17A illustrate the follower 1223 as a gear. Multiple followers 1223 are respectively arranged on multiple directional antennas 121, and the axes of the multiple followers 1223 are respectively collinear with the rotation axes of the directional antennas 121. The multiple followers 1223 are arranged circumferentially around the driving gear 1222 and mesh with the driving gear 1222. This drives the multiple followers 1223 to rotate around their axes, thereby driving the multiple directional antennas 121 to rotate around their rotation axes.

[0177] This driving device 122 uses a single driving member 1221 to simultaneously drive multiple directional antennas 121, thus reducing costs. Furthermore, the transmission ratios between the driving gear and the multiple driven members can be individually designed to achieve different rotational angular velocities for the multiple directional antennas 121, thereby adapting to different application scenarios.

[0178] In the above embodiment, the driving gear 1222 and the driven member 1223 can be directly meshed for transmission, or at least one transmission gear can be provided between the driving gear 1222 and the driven member 1223 to achieve indirect meshing transmission via the transmission gear. The provision of the transmission gear can increase the distance between the driving gear 1222 and the driven member 1223, making it easier to place the driven member 1223 and the directional antenna 121 in an area with ample space. Figure 17A illustrates direct meshing between the driving gear 1222 and the driven member 1223, and this should not be considered a special limitation of the present application.

[0179] In this embodiment, the driving gear 1222 can be directly meshed with the driven member 1223, or the same number of transmission gears can be provided between the driving gear 1222 and multiple driven members 1223 to ensure that the multiple directional antennas 121 rotate in the same direction. At the same time, the transmission ratios between the driving gear 1222 and multiple driven members 1223 can be designed to be the same to ensure that the multiple directional antennas 121 rotate at the same angular velocity, thereby achieving synchronous, unidirectional, and uniform drive. Conversely, different numbers of transmission gears and / or different transmission ratios can be provided to achieve synchronous drive with different directions and / or speeds to accommodate different application scenarios.

[0180] In some embodiments, the transmission ratio between the driving gear 1222 and the driven member 1223 can be 1. In this way, during operation of the antenna assembly 12, the rotational angular velocity of the driving member 1221, the rotational angular velocity of the driving gear 1222, and the rotational angular velocity of the driven member 1223 are the same, which can simplify control difficulty.

[0181] The synchronous driving device 122 described in the above embodiment can solve most scenario problems, but there are still some more advanced scenario requirements that cannot be met. For example, when a directional antenna covers the target user, when the target user moves from the sector where the directional antenna is located to another sector, the directional antenna rotates with the target user device, which will cause multiple other users in the original sector to be disconnected, so the user experience may be poor.

[0182] To address the above issues, please refer to Figures 19 and 20. Figure 19 is a schematic structural diagram of an antenna assembly 12 according to yet another embodiment of the present application, and Figure 20 is an exploded view of the antenna assembly 12 shown in Figure 19. The antenna assembly 12 shown in Figure 20 conceals a directional antenna 121. The antenna assembly 12 shown in this embodiment differs from the antenna assembly 12 shown in Figures 16, 17A, and 17B in that, in this embodiment, the drive mechanism 122 includes, in addition to a driving member 1221, a driving gear 1222, and a plurality of driven members 1223, a shift assembly 1224. The shift assembly 1224 is configured to selectively disengage the driving gear 1222 from at least one of the plurality of driven members 1223. This stops the rotation of the at least one driven member 1223 and the directional antenna 121 disposed thereon, while the remaining driven members 1223 can rotate with the driving gear 1222.

[0183] It should be noted that the number of the at least one follower 1223 is less than the number of the multiple followers 1223. Based on this, the driving gear 1222 can selectively separate from at least one of the multiple followers 1223. In other words, the driving gear 1222 can selectively engage with at least one of the multiple followers 1223 to achieve beam pointing adjustment of the at least one directional antenna 121.

[0184] Specifically, the difference between the number of the plurality of followers 1223 and the number of the at least one follower 1223 may be one, or may be two or more.

[0185] When the difference between the number of the plurality of followers 1223 and the number of the at least one follower 1223 is one, the driving gear 1222 may selectively engage with one of the plurality of followers 1223 to achieve independent driving of each directional antenna 121 .

[0186] When the difference between the number of the plurality of followers 1223 and the number of the at least one follower 1223 is more than two, the driving gear 1222 can selectively engage with more than two of the plurality of followers 1223 to achieve synchronous driving of the more than two followers 1223 .

[0187] It should be noted that the difference between the number of the plurality of followers 1223 and the number of the at least one follower 1223 may remain constant over time or may vary over time. For example, at a certain moment, the difference between the number of the plurality of followers 1223 and the number of the at least one follower 1223 is one, and the driving gear 1222 may selectively engage with one of the plurality of followers 1223 to achieve independent driving of each directional antenna 121. At another moment, the difference between the number of the plurality of followers 1223 and the number of the at least one follower 1223 is two, and the driving gear 1222 may selectively engage with two of the plurality of followers 1223 to achieve synchronous driving of the two followers 1223.

[0188] In this way, by shifting the gears of the shift component 1224, at least one follower 1223 can be stopped from rotating to fix the position of the directional antenna 121, so that the at least one directional antenna 121 maintains the current coverage state. At the same time, at least one other directional antenna 121 is driven to rotate to change its beam direction. This driving method is an asynchronous driving method, which can simultaneously meet the high-speed Internet access requirements of multiple user devices to improve the edge coverage performance of multiple sectors and multiple users. It has better flexibility and a wider range of applications. Different coverage strategies can be used under different optimization strategies, such as global throughput optimization or VIP priority, business scenario priority, etc.

[0189] The following examples further illustrate the above technical effects:

[0190] Please refer to Figure 21, which is a top view of the antenna assembly 12 shown in Figures 19 and 20 at a specific moment. The three directional antennas 121 are a first directional antenna 121a, a second directional antenna 121b, and a third directional antenna 121c. The beams of the first directional antenna 121a, the second directional antenna 121b, and the third directional antenna 121c are located within sectors F1, F2, and F3, respectively. At the moment shown in Figure 21, a first target user device (for example, users 1-10) and a second target user device (for example, user VIP) are located within sector F1. Through electrical switching, the first directional antenna 121a is selected for operation to simultaneously serve users 1-10 and user VIP.

[0191] When the positions of users 1 to 10 remain unchanged and user VIP moves from sector FI to sector F2 or sector F3, the driving gear 1222 can be separated from the driven member 1223 connected to the first directional antenna 121a through the shift assembly 1224 to fix the positions of the first directional antenna 121a and the third directional antenna 121c, so that the first directional antenna 121a can serve users 1 to 10 and drive the second directional antenna 121b and / or the third directional antenna 121c to rotate to serve user VIP.

[0192] For example, when user VIP moves from sector F1 to sector F2, refer to FIG. 22, which is a top view of antenna assembly 12 shown in FIG. 19 and FIG. 20, when user VIP moves from sector F1 to sector F2. The shift assembly 1224 simultaneously disengages driving gear 1222 from driven member 1223 connected to first directional antenna 121a and driven member 1223 connected to third directional antenna 121c. This maintains the positions of first directional antenna 121a and third directional antenna 121c relative to the positions shown in FIG. 21, ensuring that first directional antenna 121a covers users 1-10. The angle α of first directional antenna 121a within sector F1 is recorded. And determine whether the second directional antenna 121b can cover the user VIP. If the second directional antenna 121b can cover the user VIP, there is no need to adjust the angle of the second directional antenna 121b. If the second directional antenna 121b cannot cover the user VIP, only drive the second directional antenna 121b to rotate to cover the user VIP, thereby achieving simultaneous coverage of users 1 to 10 and user VIP, and being able to simultaneously meet the high-speed Internet access needs of multiple user devices, and at the same time record the angle β of the second directional antenna 121b in sector F2.

[0193] It should be noted that the above-mentioned process of covering users 1 to 10 and user VIP at the same time when user VIP moves from sector F1 to sector F2 can also be: only the shifting component 1224 is used to separate the driving gear 1222 from the driven member 1223 connected to the first directional antenna 121a, so that the position of the first directional antenna 121a remains unchanged relative to the position at the moment shown in Figure 21, so as to cover users 1 to 10 and record the angle α of the first directional antenna 121a in sector F1. And determine whether the second directional antenna 121b can cover the user VIP. If the second directional antenna 121b can cover the user VIP, there is no need to adjust the angle of the second directional antenna 121b; if the second directional antenna 121b cannot cover the user VIP, the second directional antenna 121b and the third directional antenna 121c are synchronously driven to rotate so that the second directional antenna 121b covers the user VIP. In this way, simultaneous coverage of users 1 to 10 and user VIP can be achieved, and the high-speed Internet access requirements of multiple user devices can be met at the same time. At the same time, the angle β of the second directional antenna 121b in sector F2 and the angle γ1 of the third directional antenna 121c in sector F3 are recorded.

[0194] Based on either of the two aforementioned implementations, when the user VIP moves further from sector F2 to sector F3, refer to Figure 23, which is a top view of the antenna assembly 12 shown in Figures 19 and 20 when the user VIP moves further from sector F2 to sector F3. The shift assembly 1224 simultaneously separates the driving gear 1222 from the driven member 1223 connected to the first directional antenna 121a and also separates the driving gear 1222 from the driven member 1223 connected to the second directional antenna 121b, thereby maintaining the positions of the first directional antenna 121a and the second directional antenna 121b relative to the positions shown in Figure 22. It is also determined whether the third directional antenna 121c can cover the user VIP. If the third directional antenna 121c can cover the user VIP, there is no need to adjust the angle of the third directional antenna 121c. If the third directional antenna 121c cannot cover the user VIP, only the third directional antenna 121c is driven to rotate to cover the user VIP. In this way, simultaneous coverage of users 1 to 10 and user VIP can also be achieved, and the high-speed Internet access needs of multiple user devices can be met at the same time. At the same time, the angle γ2 of the third directional antenna 121c in sector F3 is recorded.

[0195] Based on the above, if the user VIP is not in sector F3, the first directional antenna 121a is determined to be able to cover the user VIP at angle α. If so, there is no need to adjust the angle of the first directional antenna 121a. If not, the shift assembly 1224 is used to shift the second and third directional antennas 121b, 121c relative to their positions at the time shown in FIG23. Only the first directional antenna 121a is driven to rotate to cover the user VIP, and the new angle of the first directional antenna 121a within sector F1 is recorded.

[0196] After completing at least one round-robin, each time the shift assembly 1224 engages only one follower 1223 with the driving gear 1222, independent control is achieved by simply referencing the previous angles α, β, and γ2 and making appropriate adjustments. Different optimization strategies can be employed under different conditions, such as global throughput optimization, VIP priority, or business scenario priority. The above embodiment utilizes an optimization strategy based on VIP priority.

[0197] In some special scenarios, please refer to Figure 24, which is an overhead view of the antenna assembly 12 shown in Figures 19 and 20 when the user VIP moves to the overlapping line position of sectors F2 and F3. At this moment, the user VIP is located in both sector F2 and sector F3, and can be switched through the shift assembly 1224 to drive the second directional antenna 121b and the third directional antenna 121c to rotate in turn, so that the second directional antenna 121b and the third directional antenna 121c both cover the user VIP.

[0198] In the above embodiment, the shift assembly 1224 has various structural forms. For example, multiple driven members 1223 are fixed at different positions, and by driving the entire assembly consisting of the driving member 1221 and the driving gear 1222 to move, the driving gear 1222 can selectively engage with one of the multiple driven members 1223, thereby achieving gear shifting. For another example, multiple driven members 1223 can be fixed at different positions, and the position of the driving member 1221 is fixed. Under the premise that the driving member 1221 can drive the driving gear 1222 to rotate, the driving gear 1222 is driven to move, so that the driving gear 1222 can selectively engage with one of the multiple driven members 1223, thereby achieving gear shifting. No specific limitation is given here.

[0199] In one possible implementation, please continue to refer to Figure 20 , a plurality of followers 1223 are arranged circumferentially around the driving gear 1222, and a gap exists between the driving gear 1222 and the plurality of followers 1223. On this basis, please continue to refer to Figure 20 , the shift assembly 1224 includes a plurality of transmission gears 1224a and a plurality of linear drive mechanisms 1224b. The plurality of transmission gears 1224a are all in a first position, and the plurality of transmission gears 1224a are respectively disposed in the gaps between the driving gear 1222 and the plurality of followers 1223, and the transmission gears 1224a are meshed with the driving gear 1222 and the followers 1223. The plurality of linear drive mechanisms 1224b are respectively connected to the plurality of transmission gears 1224a, and the linear drive mechanisms 1224b are used to drive the transmission gears 1224a to reciprocate in a direction parallel to the first axis O1, so that the transmission gears 1224a switch between the first position and the second position. When the transmission gear 1224a is in the first position, please refer to Figure 25, which is a structural schematic diagram of the driving gear 1222, a driven member 1223, a directional antenna 121 and the shift assembly 1224 in the antenna assembly 121 shown in Figure 20 when the transmission gear 1224a is in the first position. The transmission gear 1224a is located in the gap between the driving gear 1222 and the driven member 1223, and is engaged with the driving gear 1222 and the driven member 1223. The rotational motion of the driving gear 1222 can be transmitted to the driven member 1223 via the transmission gear 1224a, thereby driving the directional antenna 121 where the driven member 1223 is located to rotate. When the transmission gear 1224a is in the second position, please refer to Figure 26, which is a structural schematic diagram of the driving gear 1222, a driven member 1223, a directional antenna 121 and the shift assembly 1224 in the antenna assembly 121 shown in Figure 20 when the transmission gear 1224a is in the second position. The transmission gear 1224a is located outside the gap between the driving gear 1222 and the driven member 1223, and is separated from the driving gear 1222 and the driven member 1223. The rotational motion of the driving gear 1222 cannot be transmitted to the driven member 1223, so that the driven member 1223 cannot be driven to rotate, and the directional antenna 121 where the driven member 1223 is located cannot be driven to rotate.

[0200] In this way, by controlling the plurality of linear drive mechanisms 1224b, the driving gear 1222 can be selectively engaged with one of the plurality of driven members 1223 to achieve gear shifting. This structure is simple and compact.

[0201] In some embodiments, when the transmission gear 1224a is in the first position, the transmission ratio of the gear transmission mechanism composed of the driving gear 1222, the transmission gear 1224a, and the driven member 1223 can be 1. In this way, during operation of the antenna assembly 12, the rotational angular velocity of the driving member 1221, the rotational angular velocity of the driving gear 1222, and the rotational angular velocity of the driven member 1223 are the same, which can simplify control.

[0202] In the above embodiment, the linear drive mechanism 1224b can be a linear motor, an electric push rod, a hydraulic rod, etc., without specific limitation herein. In some embodiments, please refer to FIG. 27 , which is a schematic diagram of the structure of the linear drive mechanism 1224b in the antenna assembly 12 shown in FIG. 20 . In this embodiment, the linear drive mechanism 1224b includes a magnetic member M1, an electromagnet M2, an elastic return member M3, and a control circuit M4.

[0203] Magnetic component M1 is a structural component that can be attracted by a magnet. Materials for magnetic component M1 include, but are not limited to, iron (Fe), cobalt (Co), nickel (Ni), and their alloys. Electromagnet M2 includes a magnetic core M21 and a coil M22 wound around core M21. When coil M22 is energized, electromagnet M2 becomes magnetic and attracts magnetic component M1. When coil M22 is de-energized, the magnetism of electromagnet M2 disappears, and the magnetic attraction force ceases.

[0204] The magnetic component M1 and the electromagnet M2 are arranged parallel to the first axis O1. One of the magnetic component M1 and the electromagnet M2 is fixed to the transmission gear 1224a, and the other is fixed relative to the first bracket 123. In the embodiment shown in Figure 21, the electromagnet M2 is fixed to the transmission gear 1224a, and the magnetic component M1 is fixed relative to the first bracket 123. In some embodiments, referring to Figure 27, the antenna assembly 12 also includes a third bracket 131, which is fixed to the first bracket 123. The magnetic component M1 is fixed to the third bracket 131, thereby achieving relative fixation between the magnetic component M1 and the first bracket 123. When the coil of the electromagnet M2 is energized, the electromagnet M2 becomes magnetic and can attract the magnetic component M1.

[0205] The elastic return member M3 is connected to the transmission gear 1224a and is used to perform an elastic return function. The elastic return member M3 includes, but is not limited to, a coil spring, a leaf spring, and a rubber strip. In the embodiment shown in Figure 27 , the elastic return member M3 is a coil spring, the axis of which is parallel to the first axis O1. One end of the coil spring is fixed to the transmission gear 1224a, and the other end is fixed relative to the first bracket 123.

[0206] The control circuit M4 is connected to the electromagnet M2. Specifically, the control circuit M4 is connected to the coil M22 of the electromagnet M22. The control circuit M4 is used to control the electromagnet M2 to be energized or de-energized. When the electromagnet M2 is energized, there is a magnetic attraction F between the electromagnet M2 and the magnetic part M1. n , the magnetic attraction force F n This causes transmission gear 1224a to move from the first position to the second position. Simultaneously, elastic return member M3 deforms, accumulating an elastic return force. When electromagnet M2 is de-energized, the magnetic attraction between electromagnet M2 and magnetic member M1 disappears, and the elastic return force generated by elastic return member M3 drives transmission gear 1224a back from the second position to the first position. This reciprocating drive of transmission gear 1224a between the first and second positions is achieved, resulting in a simple structure and convenient control.

[0207] In the above embodiment, the elastic return member M3 may be omitted and the magnetic member M1 may be replaced with a magnet or electromagnet. The control circuit M4 may be used to control the direction of the current input to the electromagnet M2, so that the electromagnet M2 and the magnet or electromagnet alternate between mutual attraction and mutual repulsion, thereby achieving reciprocating drive of the transmission gear 1224a between the first position and the second position. This structure is less complex and less difficult to assemble.

[0208] In some embodiments, the control circuit M4 can be integrated into the circuit board assembly 125. In some embodiments, please refer to Figure 28, which is a circuit block diagram of the antenna assembly 12 shown in Figure 20. In this embodiment, the circuit board assembly 125 used to implement the signal transmission and reception functions of the antenna group 130 and the circuit used to drive the driver 1221 are the same as the circuit shown in Figure 14 and are not described in detail here. On this basis, the circuit board assembly 125 also includes the above-mentioned control circuit M4, which can include a power supply circuit M41, a selection switch M42, and a processor 1251. The selection switch M42 is arranged between the power supply circuit M41 and the electromagnet M2 of the multiple linear drive mechanisms 1224b. The processor 1251 is connected to the selection switch M42 and is used to control the selection switch M42 so that the power supply circuit M41 can selectively supply power to the electromagnet M2 of at least one of the multiple linear drive mechanisms 1224b. Thus, the selector switch M42 can be used to select the power supply circuit M41 to connect to the electromagnet M2 of at least one of the plurality of linear drive mechanisms 1224b to provide power, thereby selecting at least one of the plurality of transmission gears 1224a to move from a first position to a second position, thereby selectively separating the driving gear 1222 from at least one of the plurality of driven members 1223 to achieve gear shifting. This control circuit M4 has a simple structure and is easy to implement.

[0209] In the above embodiment, please continue to refer to FIG. 28 , the processor 1251 may also be connected to the power circuit M41 to control the power circuit M41 to output an electrical signal.

[0210] In order to achieve independent driving of multiple directional antennas 121, in some other embodiments, multiple independent rotating drive components (such as servo motors) can also be used to drive multiple directional antennas 121 separately. The control principle of this structure is simple and easy to control. This driving method is also an asynchronous driving method. This driving method can simultaneously meet the high-speed Internet access requirements of multiple user devices to improve the edge coverage performance of multiple sectors and multiple users. It has better flexibility and a wider range of applications. Different coverage strategies can be used under different optimization strategies, such as global throughput optimization or VIP priority, business scenario priority, etc.

[0211] In the antenna assemblies provided in the aforementioned embodiments, to adjust the beam pointing direction of the directional antenna 121, the driving device 122 drives the entire directional antenna 121 to rotate. However, since the directional antenna 121 typically includes a radiator and a reflector, rotating the entire directional antenna 121 or the reflector alone can achieve the purpose of changing the beam pointing direction. Based on this, in addition to driving the entire directional antenna 121 to rotate relative to the housing 11 to adjust the beam pointing direction of the directional antenna 121, the driving device 122 can also achieve the purpose of adjusting the beam pointing direction of the directional antenna 121 by driving the reflector of the directional antenna 121 to rotate relative to the housing 11.

[0212] In some embodiments, please refer to Figures 29 and 30. Figure 29 is a schematic diagram of the structure of an antenna assembly 12 according to yet another embodiment of the present application, and Figure 30 is an exploded view of the antenna assembly 12 shown in Figure 29. The antenna assembly 12 shown in this embodiment differs from the antenna assembly 12 shown in Figures 16, 17A, and 17B in that: in this embodiment, the directional antenna 121 includes a radiator 1211 and a reflector 1212. A first bracket 123 is fixed relative to the housing 11. Specifically, the first bracket 123 can be fixed to the second bracket 124. On this basis, the radiators 1211 of the multiple directional antennas 121 are fixed to the first bracket 123, thereby achieving relative fixation between the first bracket 123 and the housing 11. It should be noted that Figures 29 and 30 do not show the entire first bracket 123; specifically, the portion of the first bracket 123 that secures the radiators 1211 of the multiple directional antennas 121 is not shown. The reflectors 1212 of the multiple directional antennas 121 are each rotatable about an axis relative to the radiator 1211. In some embodiments, the reflective plates 1212 of multiple directional antennas 121 can be rotatably connected to the first bracket 123 around an axis, and the driving device 122 is used to drive the reflective plates 1212 of the multiple directional antennas 121 to rotate around their rotation axes respectively, so as to adjust the beam pointing of the multiple directional antennas 121 in multiple sectors respectively.

[0213] For example, please refer to Figures 29 and 30. The reflecting plates 1212 of the three directional antennas 121 are rotatably connected to the first bracket 123 around the sixth axis O6, the seventh axis O7 and the eighth axis O8 respectively. The driving device 122 is used to drive the reflecting plates 1212 of the three directional antennas 121 to rotate around the sixth axis O6, the seventh axis O7 and the eighth axis O8 respectively, so as to adjust the beam pointing of the three directional antennas 121 in the three sectors respectively.

[0214] In this way, by fixing the radiators 1211 of the multiple directional antennas 121 and driving the reflectors 1212 of the multiple directional antennas 121 to rotate, the beam direction of the directional antennas 121 is adjusted. During the adjustment process, the positions of the radiators 1211 of the multiple directional antennas 121 and the circuit board assembly 125 are fixed, and the feeder line 126 connected between the radiator 1211 and the circuit board assembly 125 does not swing, thereby minimizing the possibility of the feeder line 126 being tangled, tangled, or worn.

[0215] In some embodiments, referring to Figures 29 and 30 , a reflector 1212 is positioned between the radiator 1211 and the first axis O1. The reflector 1212 is an arc-shaped plate, with its centerline collinear with its rotation axis. The arc-shaped plate has opposing concave surfaces 1212a and convex surfaces 1212b, with the concave surface 1212a facing the radiator 1211 and the convex surface 1212b facing the first axis O1. A driving device 122 is configured to rotate the arc-shaped plate about its centerline to adjust the beam directions of the multiple directional antennas 121 within multiple sectors. As a result, when the reflector 1212 rotates, the performance of the directional antenna 121 is minimally affected. Specifically, see Figures 31-33. Figure 31 shows the directional pattern of a directional antenna 121 in the antenna assembly 12 shown in Figure 29 when the reflector 1212 is rotated to 60°. Figure 32 shows the directional pattern of a directional antenna 121 in the antenna assembly 12 shown in Figure 29 when the reflector 1212 is rotated to 0°. Figure 33 shows the directional pattern of a directional antenna 121 in the antenna assembly 12 shown in Figure 29 when the reflector 1212 is rotated to -30°. As can be seen from Figures 31-33, at different rotation angles of the reflector 1212, the directional pattern of the directional antenna 121 has minimal distortion, the maximum gain direction of the directional pattern is consistent with the rotation amount, and the maximum gain fluctuation is minimal, specifically less than 0.5 dB.

[0216] In the above embodiment, the driving mode of the driving device 122 includes but is not limited to a synchronous driving mode and an asynchronous driving mode. Please refer to Figure 34, which is a top view of the assembly structure of the directional antenna 121 and the driving device 122 in the antenna assembly 12 shown in Figure 29. In this embodiment, the driving device 122 includes a driving member, a driving gear 1222 and a plurality of driven members 1223. The driving member is a rotating driving member, which is connected to the driving gear 1222 and is used to drive the driving gear 1222 to rotate. The driven member 1223 is a gear or a rack extending along an arc. In this embodiment, the driven member 1223 is a rack extending along an arc. The plurality of driven members 1223 are respectively arranged on the reflective plates 1212 of the plurality of directional antennas 121, and the axes of the plurality of driven members 1221 are respectively collinear with the center line of the reflective plates 1212 where they are located. The plurality of follower members 1223 are arranged around the driving gear 1222 in a circumferential direction and mesh with the driving gear 1222 to drive the plurality of follower members 1223 to rotate around their respective axes.

[0217] This synchronous drive method is employed. Because the rotation axes of the multiple directional antennas 121 are not collinear with the first axis O1, the positional accuracy requirements for the reflectors 1212 of the multiple directional antennas 121 relative to the first bracket 123, as well as the relative positional accuracy requirements for the reflectors 1212 of the multiple directional antennas 121, are lower, simplifying installation. Furthermore, the structure of the drive device 122 can be designed to achieve different angular velocities and / or different rotational directions for the reflectors 1212 of the multiple directional antennas 121, thereby adapting to the needs of various application scenarios.

[0218] In some other embodiments, please refer to Figure 36, which is a top view of another assembly structure of the directional antenna and the driving device 122 in the antenna assembly 12 shown in Figure 29. In this embodiment, in addition to the driving member 1221, the driving gear 1222 and the multiple driven members 1223 in the embodiment shown in Figure 34 above, the driving device 122 also includes a shift assembly 1224. The shift assembly 1224 is used to selectively separate the driving gear 1222 from at least one of the multiple driven members 1223, so that the at least one driven member 1223 and the reflector 1212 provided on the at least one driven member 1223 stop rotating, and the remaining driven members 1223 can rotate with the driving gear 1222. The structural form of the shift assembly 1224 can be the same as the structural form of the aforementioned shift assembly 1224, and will not be repeated here.

[0219] In this way, by shifting the gears of the shifting component 1224, multiple directional antennas 121 can be independently driven in multiple sectors. This asynchronous driving method can simultaneously meet the high-speed Internet access requirements of multiple user devices. It has excellent flexibility and a wide range of applications. Different optimization strategies can be implemented under different optimization policies, such as global throughput optimization, VIP priority, business scenario priority, etc.

[0220] In order to achieve independent driving of the reflectors 1212 of multiple directional antennas 121, in some other embodiments, the driving device 122 may include multiple driving elements. The driving elements are rotating elements. The number of the multiple driving elements is equal to the number of the multiple directional antennas 121, and the multiple driving elements correspond one-to-one to the multiple directional antennas 121. Each driving element is connected to the reflector 1212 of the corresponding directional antenna 121, and the driving element is used to drive the reflector 1212 to rotate around its center line. In other words, multiple independent rotating driving elements (such as servo motors) are used to drive the reflectors 1212 of the multiple directional antennas 121 respectively. This structure has a simple control principle and is easy to control. The driving method is asynchronous, which can simultaneously meet the high-speed Internet access requirements of multiple user devices to improve the edge coverage performance of multiple sectors and multiple users. It has excellent flexibility and a wide range of applications. Different coverage strategies can be implemented under different optimization strategies, such as global throughput optimization, VIP priority, business scenario priority, etc.

[0221] In some embodiments, please refer to Figure 37, which illustrates a block diagram of the internal circuitry and algorithms of a wireless access device 10 provided in some embodiments of the present application. The wireless access device 10 can be configured to determine the location and trajectory of each user device. This allows the wireless access device 10 to determine corresponding coverage and tracking strategies based on the location and trajectory of each user device.

[0222] In the above embodiment, there are multiple ways for the wireless access device 10 to determine the location and movement trajectory of the user equipment.

[0223] For example, the wireless access device 10 is configured to obtain the position and movement trajectory of a user device by traversing detection using a directional antenna 121. Specifically, the driving device 122 can drive multiple directional antennas 121 to rotate synchronously or asynchronously to perform traversing detection at a small angle within the sector in which they are located, thereby obtaining the position and movement trajectory of each user device, thereby facilitating user device tracking.

[0224] As another example, the wireless access device 10 can also obtain the location and movement trajectory of the user device through conventional means such as artificial intelligence (AI), self-learning, time statistics, positioning technology, and probability statistics. Among them, the positioning antennas used in the positioning technology include but are not limited to ultra-wideband (UWB) antennas and artificial intelligence & internet of things (AIoT) sensing antennas. Among them, AIoT (artificial intelligence Internet of Things) = AI (artificial intelligence) + IoT (the internet of things).

[0225] After the location of each user equipment is determined, the sector in which each user equipment is located can be determined so that a directional antenna of the corresponding sector can be used to meet the wireless coverage requirement of the user equipment.

[0226] After determining the location of the user equipment, user equipment in different sectors can be grouped to facilitate OFDMA and MU-MIMO services for all users within the coverage area. User equipment in the same sector can directly provide OFDMA services. MU-MIMO service refers to a wireless communication system in which a wireless access device 10 simultaneously serves multiple user equipment, fully utilizing the antenna's spatial resources to communicate with multiple user equipment simultaneously. Specifically, the wireless access device 10 sends different data streams to different user equipment on the same channel at the same time, leveraging spatial multiplexing gain and multi-user diversity gain to improve the overall system throughput and free up more time. Therefore, high non-correlation between user equipment is required. Therefore, two polarized antennas in the same sector can provide MU-MIMO service for that sector. UE20 in different sectors also have low channel correlation, but because data is transmitted in time division, MU-MIMO service cannot be provided. If multiple sectors can transmit data simultaneously, MU-MIMO service can also be provided.
