Description

Technical Field

[0001] This application relates to the field of communication equipment technology, and in particular to a wireless router and its control method. Background Technology

[0002] Currently, wireless routers (such as home wireless routers) are used for user internet access and wireless coverage. A wireless router can be seen as a repeater, forwarding wireless or wired broadband network signals through an antenna to nearby wireless network devices (such as laptops, mobile phones, tablets, smart TVs, wireless routers, etc.).

[0003] Most existing wireless routers use omnidirectional antennas to achieve wireless coverage. Omnidirectional antennas exhibit uniform radiation at 360° in the horizontal direction, which is commonly referred to as non-directional. However, omnidirectional antennas have relatively low gain, typically only 3dBi to 6dBi, and their communication distance is short, with slow signal forwarding speed. This means that these wireless routers can only serve ordinary user devices and cannot serve medium- to long-range devices in weak fields or high-speed devices, thus limiting the application of existing wireless routers. Summary of the Invention

[0004] This application provides a wireless router and its control method to address the problem of how to improve the applicability of wireless routers.

[0005] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0006] In a first aspect, a wireless router is provided, comprising an omnidirectional antenna, a directional antenna, and a driving device. The driving device is connected to the directional antenna and is used to drive the directional antenna to rotate so that the beam direction of the directional antenna coincides with the direction of a target beam in a beam lookup table, wherein the target beam can cover a target device. The beam lookup table comprises a set of beams formed when the directional antenna rotates to multiple different orientations under the drive of the driving device.

[0007] In this embodiment, while using an omnidirectional antenna to meet the access needs of ordinary devices, a directional antenna with high gain and adjustable beam direction can be used to meet the access needs of medium- and long-range weak field devices and high-speed devices, thereby improving the versatility of wireless router applications. Furthermore, during the rotation of the directional antenna using a driving device, it is only necessary to align the beam direction of the directional antenna with the direction of the target beam among a limited number of beams in the beam lookup table to adjust the directional antenna to the position covering the target device. This eliminates the need to traverse all the directions the directional antenna can rotate to under the drive of the driving device, thus reducing control difficulty, power consumption, and latency.

[0008] In one possible implementation of the first aspect, a driving device is used to drive the directional antenna to rotate about a first axis. Multiple beams in a beam lookup table form multiple beam subsets, which are arranged circumferentially along the first axis. Each beam subset includes at least a first beam pointing perpendicular to the first axis. Thus, when the directional antenna rotates until its beam direction coincides with the direction of the multiple first beams, it can cover target devices in the horizontal plane, making the wireless router suitable for large, single-level house structures.

[0009] In one possible implementation of the first aspect, along the circumference of the first axis, the angle between the first beams in two adjacent beam subsets is greater than or equal to the step accuracy angle driven by the driving device around the first axis, and less than or equal to the first beam angle of the directional antenna. The first beam angle refers to the angle between two directions located on either side of the maximum radiation direction, where the radiated power decreases by a first preset threshold, in a plane perpendicular to the first axis when the beam pointing of the directional antenna is perpendicular to the first axis. In this way, the beam lookup table is complete within a 360° range along the circumference of the first axis, and the beam pointing of the directional antenna can be adjusted to multiple positions within the 360° range of the first axis, enabling the directional antenna to cover target devices at any location in the horizontal plane.

[0010] In one possible implementation of the first aspect, the angle between the first beams in two adjacent beam subsets along the circumference of the first axis is equal to the first beam angle of the directional antenna. This results in a smaller number of beams in the beam lookup table, lower control complexity, and lower power consumption and latency.

[0011] In one possible implementation of the first aspect, the driving device is further configured to drive the directional antenna to rotate about a second axis; the second axis is perpendicular to the first axis and perpendicular to the beam direction of the directional antenna. The beam subset includes multiple beams arranged circumferentially along the second axis, with the first beam being one of these multiple beams. In this way, the multiple beams in the beam lookup table are distributed within a three-dimensional space. When the directional antenna rotates until its beam direction coincides with the direction of the multiple beams within that three-dimensional space, it can cover the target device within that three-dimensional space. The wireless router can then be applied to house structures such as villas and duplexes.

[0012] In one possible implementation of the first aspect, along the circumference of the second axis, the angle between two adjacent beams within the beam subset is greater than or equal to the step accuracy angle driven by the second driving device around the second axis, and less than or equal to the second beam angle of the directional antenna. The second beam angle refers to the angle between two directions located on either side of the maximum radiation direction, where the radiated power decreases by a second preset threshold, in a plane perpendicular to the second axis, when the beam pointing of the directional antenna is perpendicular to the first axis. In this way, the beam lookup table is complete in three-dimensional space, and the beam pointing of the directional antenna can be adjusted to multiple positions within three-dimensional space, enabling the directional antenna to cover target devices at any location within three-dimensional space.

[0013] In one possible implementation of the first aspect, along the circumference of the second axis, the angle between two adjacent beams in the beam subset is equal to the second beam angle of the directional antenna. This results in a smaller number of beams in the beam lookup table, lower control complexity, and lower power consumption and latency.

[0014] In one possible implementation of the first aspect, the wireless router further includes a controller and a detection system. The controller is electrically connected to a drive unit and controls the drive unit to sequentially rotate the directional antenna to multiple positions so that the beam pointing of the directional antenna coincides with the pointing of multiple beams in a beam lookup table. The detection system detects the signal quality received by the directional antenna from the target device when the beam pointing of the directional antenna coincides with the pointing of multiple beams in the beam lookup table. This signal quality can be evaluated by at least one of the following indicators: received signal strength, error rate, throughput, and channel state information. When the signal quality is comprehensively evaluated by multiple of these indicators, the multiple indicators can be weighted to obtain a comprehensive indicator for evaluation, or they can be evaluated separately; no specific limitation is made here. The controller is also electrically connected to the detection system and, based on the multiple signal quality indicators detected by the detection system, determines the target beam in the beam lookup table and controls the drive unit to rotate the directional antenna so that the beam pointing of the directional antenna coincides with the pointing of the target beam in the beam lookup table. This wireless router has a simple structure, requires no dedicated positioning device, and therefore has low cost.

[0015] In one possible implementation of the first aspect, the wireless router further includes a positioning device and a controller. The positioning device is used to acquire the location information of the target device. The controller is electrically connected to the positioning device and is used to determine the target beam in the beam lookup table based on the location information acquired by the positioning device, and control the driving device to drive the directional antenna to rotate so that the beam pointing of the directional antenna coincides with the pointing of the target beam in the beam lookup table. This wireless router does not require polling to find the target beam, can quickly determine the target beam, has a fast response, and a short latency.

[0016] In one possible implementation of the first aspect, the positioning device is a UWB antenna.

[0017] In one possible implementation of the first aspect, a radio frequency transceiver system is also included. The radio frequency transceiver system has multiple signal output terminals, at least one omnidirectional antenna, at least one directional antenna, and the sum of the number of omnidirectional antennas and the number of directional antennas is greater than the number of signal output terminals of the radio frequency transceiver system. A switching switch is also provided between the multiple signal output terminals of the radio frequency transceiver system and the omnidirectional antennas and the directional antennas. The switching switch is used to select that the multiple signal output terminals of the radio frequency transceiver system are electrically connected to any multiple antennas of at least one omnidirectional antenna and at least one directional antenna, so that the wireless router can switch between multiple usage scenarios.

[0018] Secondly, a control method for a wireless router is also provided. The wireless router includes an omnidirectional antenna, a directional antenna, and a driving device, with the driving device connected to the directional antenna. The control method includes:

[0019] The signal quality received by the omnidirectional antenna from the first target device is obtained to obtain the first signal quality;

[0020] When the first signal quality is less than a third preset threshold, the directional antenna is driven to rotate by the driving device so that the beam direction of the directional antenna coincides with the direction of the target beam in the beam lookup table, and the target beam can cover the first target device. The beam lookup table includes a set of beams formed when the directional antenna rotates to multiple different orientations under the drive of the driving device.

[0021] In this way, while using omnidirectional antennas to meet the access needs of ordinary devices, directional antennas with higher gain and adjustable beam direction can meet the access needs of medium- and long-range devices in weak fields and high-speed devices, thereby improving the versatility of wireless router applications. Furthermore, during the rotation of the directional antenna using a driving device, it is only necessary to align the beam direction of the directional antenna with the target beam direction among a limited number of beams in the beam lookup table to adjust the directional antenna to the position covering the target device. It is not necessary to traverse all the directions the directional antenna can rotate to under the drive of the driving device, thus reducing control difficulty, power consumption, and latency.

[0022] In one possible implementation of the second aspect, when the first signal quality is less than a third preset threshold, before driving the directional antenna to rotate via the driving device so that the beam pointing of the directional antenna coincides with the pointing of the target beam in the beam lookup table, the control method further includes: determining the target beam in the beam lookup table. This allows for automatic target beam finding with minimal delay and high efficiency.

[0023] In one possible implementation of the second aspect, determining the target beam in a beam lookup table includes:

[0024] The directional antenna is driven by a driving device to rotate to multiple positions in sequence so that the beam pointing of the directional antenna coincides with the beam pointing of multiple beams in the beam lookup table. When the beam pointing of the directional antenna coincides with the beam pointing of multiple beams in the beam lookup table, the signal quality received by the directional antenna from the first target device is detected to obtain multiple signal qualities.

[0025] The target beam is determined from the beam lookup table based on multiple signal qualities.

[0026] In this way, the target beam is determined in the beam lookup table using a round-robin search method. This method is simple and easy to implement.

[0027] In one possible implementation of the second aspect, the driving device is used to drive the directional antenna to rotate about a first axis; multiple beams in the beam lookup table form multiple beam subsets, the multiple beam subsets are arranged circumferentially along the first axis, and the beam subsets include at least a first beam pointing perpendicular to the first axis;

[0028] A directional antenna is driven by a driving device to rotate sequentially to multiple positions so that the beam direction of the directional antenna coincides with the beam direction of multiple beams in a beam lookup table. When the beam direction of the directional antenna coincides with the beam direction of multiple beams in the beam lookup table, the signal quality received by the directional antenna from the first target device is detected to obtain multiple signal quality parameters, including:

[0029] A directional antenna is driven to rotate around a first axis by a driving device, so that the beam pointing of the directional antenna coincides with the pointing of the first beam in multiple beam subsets. When the beam pointing of the directional antenna coincides with the pointing of the first beam in multiple beam subsets, the signal quality received by the directional antenna from the first target device is detected to obtain multiple third signal qualities. Since each beam subset includes a first beam, the first beam in multiple beam subsets refers to multiple first beams, each of which belongs to the multiple beam subsets.

[0030] A target beam subset is determined based on multiple third signal qualities, and the target beam belongs to the target beam subset.

[0031] In this way, when the directional antenna is rotated so that the beam direction coincides with the direction of the multiple first beams, it can cover the target device in the horizontal plane, and the wireless router can be applied to the structure of large single-story houses.

[0032] In one possible implementation of the second aspect, the driving device is further configured to drive the directional antenna to rotate about a second axis; the second axis is perpendicular to the first axis and perpendicular to the beam direction of the directional antenna; the beam subset includes a plurality of beams arranged circumferentially along the second axis, and the first beam is one of the plurality of beams;

[0033] After determining the target beam subset, a driving device drives the directional antenna to rotate sequentially to multiple positions so that the beam direction of the directional antenna coincides with the directions of multiple beams in the beam lookup table. When the beam direction of the directional antenna coincides with the directions of multiple beams in the beam lookup table, the signal quality received by the directional antenna from the first target device is detected to obtain multiple signal qualities. The method also includes:

[0034] The directional antenna is driven to rotate around the second axis by a driving device so that the beam pointing of the directional antenna coincides with the pointing of multiple beams in the target beam subset. When the beam pointing of the directional antenna coincides with the pointing of multiple beams in the target beam subset, the signal quality received by the directional antenna from the first target device is detected to obtain multiple fourth signal qualities.

[0035] The target beam is determined from a beam lookup table based on multiple signal quality parameters, including:

[0036] The target beam is determined in the target beam subset based on multiple fourth signal qualities.

[0037] In this way, multiple beams in the beam lookup table are distributed in a three-dimensional space. When the directional antenna is rotated so that the beam direction coincides with the direction of multiple beams in the three-dimensional space, the target device in the three-dimensional space can be covered. The wireless router can be used in house structures such as villas and duplexes.

[0038] In one possible implementation of the second aspect, determining the target beam in a beam lookup table includes:

[0039] Obtain the location information of the first target device;

[0040] Based on the location information, the target beam is determined in the beam lookup table.

[0041] In this way, the wireless router does not need to poll to find the target beam, but can quickly determine the target beam, resulting in a faster response and shorter latency.

[0042] In one possible implementation of the second aspect, after obtaining the first signal quality, the control method further includes:

[0043] Determine whether the quality of the first signal is greater than or equal to the third preset threshold;

[0044] When the first signal quality is greater than or equal to a third preset threshold, the omnidirectional antenna covers the first target device. While the first signal quality is also greater than or equal to the third preset threshold, a directional antenna can also be used to cover the first target device, or the directional antenna can be stopped or used to cover other target devices. This allows for the rational allocation of resources.

[0045] In one possible implementation of the second aspect, the control method further includes:

[0046] The signal quality received by the directional antenna from the first target device is obtained to obtain the second signal quality;

[0047] The directional antenna is rotated by a driving device so that its beam direction coincides with the direction of the target beam in the beam lookup table, including:

[0048] When the first signal quality is less than the third preset threshold and the second signal quality is less than the fourth preset threshold, the directional antenna is driven to rotate by the driving device so that the beam pointing of the directional antenna coincides with the beam pointing of the target beam in the beam lookup table.

[0049] In this way, after both the omnidirectional antenna and the directional antenna under the current beam direction fail to cover the first target device, switching the beam direction of the directional antenna can quickly cover the first target device, reducing latency and power consumption in most usage scenarios.

[0050] In one possible implementation of the second aspect, obtaining the signal quality received by the directional antenna from the first target device includes:

[0051] When the first signal quality is less than a third preset threshold, the signal quality received by the directional antenna from the first target device is acquired. In this way, omnidirectional antennas are given priority to cover the first target device, and directional antennas are used to cover the first target device only when omnidirectional antennas cannot cover it, which can reduce latency and power consumption in most usage scenarios.

[0052] In one possible implementation of the second aspect, after obtaining the second signal quality, the control method further includes:

[0053] Determine whether the quality of the second signal is greater than or equal to the fourth preset threshold;

[0054] When the quality of the second signal is greater than or equal to the fourth preset threshold, the directional antenna pointing to the current beam covers the first target device. In this way, the first target device is covered by the directional antenna pointing to the current beam. While achieving coverage of the first target device, there is no need to rotate the directional antenna, thus resulting in low latency and low power consumption.

[0055] In one possible implementation of the second aspect, after the beam pointing of the directional antenna coincides with the pointing of the target beam in the beam lookup table, the control method further includes:

[0056] The directional antenna, after switching the beam direction, covers the first target device to operate.

[0057] In one possible implementation of the second aspect, after the directional antenna with switched beam pointing covers the first target device for a preset operating time, the control method further includes:

[0058] The signal quality received by the directional antenna from the first target device is obtained to obtain the second signal quality;

[0059] Determine whether the quality of the second signal is greater than or equal to the fifth preset threshold;

[0060] When the second signal quality is greater than or equal to the fifth preset threshold, the signal quality received by the omnidirectional antenna from the first target device is reacquired.

[0061] In this way, when the signal quality improves, it can be reassessed whether the omnidirectional antenna can cover the first target device, so as to achieve a reasonable allocation of resources.

[0062] In one possible implementation of the second aspect, after obtaining the second signal quality, the control method further includes:

[0063] Determine whether the quality of the second signal is less than or equal to the sixth preset threshold; if the sixth preset threshold is less than the fifth preset threshold.

[0064] When the second signal quality is less than or equal to the sixth preset threshold, the signal quality received by the omnidirectional antenna from the first target device is reacquired. In this way, when the signal quality deteriorates, an optimal antenna can be found again for coverage.

[0065] In one possible implementation of the second aspect, the control method further includes:

[0066] When the second signal quality is less than the fifth preset threshold and the second signal quality is greater than the sixth preset threshold, the directional antenna pointing to the switched beam continues to cover the first target device.

[0067] In one possible implementation of the second aspect, the control method further includes:

[0068] The priority of multiple target devices is determined based on the device information of multiple target devices. The device information includes at least one of network type, device type, wireless data request characteristics, and device usage information. The device usage information includes at least one of usage time and usage probability.

[0069] The target device with the highest priority among multiple target devices is determined as the first target device.

[0070] This can improve the rationality of beam switching.

[0103] In the embodiments of this application, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," and "fourth" may explicitly or implicitly include one or more of that feature.

[0104] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0105] In the embodiments of this application, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0106] It should be noted that the directional terms such as "coincident", "parallel", and "vertical" used in the description of the beam pointing of various components or antennas in the wireless router in the embodiments of this application all indicate approximate directions with a certain margin of error, and are not limited to absolute directional relationships.

[0107] To enhance the versatility of wireless routers, this application provides a wireless router that, in addition to serving ordinary user devices, can also serve medium- to long-range devices with weak signal strength and high-speed devices. Specifically, the wireless router provided in this application, in addition to a built-in omnidirectional antenna, additionally includes a directional antenna with adjustable beam direction. The directional antenna has a higher antenna gain (8dBi to 12dBi), so that, while the omnidirectional antenna can meet the access needs of ordinary devices, the higher-gain and adjustable-beam-direction directional antenna can also meet the access needs of medium- to long-range devices with weak signal strength and high-speed devices, thereby enhancing the versatility of the wireless router.

[0108] The embodiments of this application will be described in detail below with reference to the accompanying drawings. Before describing the embodiments of this application in detail, the application scenarios of the wireless coverage system provided by this application will be introduced first.

[0109] This application provides a wireless router, which can be an outdoor wireless router or an indoor home wireless router. The following embodiments are described using a home wireless router as an example, and should not be considered as constituting a special limitation on this application. Furthermore, the wireless router provided in this application can support at least one of the following general frequency bands: WiFi-2.4G, WiFi-5G, WiFi-6E, and above; this application does not specifically limit its use in this regard.

[0110] Please see Figure 1 , Figure 1This is a schematic diagram of the structure of a home wireless router 100 provided in some embodiments of this application. It should be noted that, for the convenience of the description of the embodiments below, [the following is a simplified description]. Figure 1 The home wireless router 100 shown is configured with an XYZ coordinate system. Specifically, the height of the wireless router 100 when in home use is defined as the Z-axis, and the plane perpendicular to the Z-axis is defined as the XY plane. It is understood that the coordinate system of the wireless router 100 can be flexibly set according to actual needs, and no specific limitations are made here.

[0111] The wireless router 100 includes a housing 10. The housing 10 serves to protect the internal electronic components from water and dust. The material of the housing 10 includes, but is not limited to, plastic. The shape of the housing 10 includes, but is not limited to, cylindrical, square, disc-shaped, triangular prism, spherical, etc. Figure 1 An example of a cylindrical housing 10 is given, but this should not be considered a particular limitation on the shape of the housing 10. In some other embodiments, the wireless router 100 may not have this housing 10.

[0112] Please continue reading. Figure 1 The wireless router 100 also includes an omnidirectional antenna 20 and a directional antenna 30. The omnidirectional antenna 20 and the directional antenna 30 are used to achieve wireless coverage for the wireless router. Specifically, the omnidirectional antenna 20 and the directional antenna 30 are used to support the transmission and reception of at least one signal from the common frequency bands of WiFi-2.4G, WiFi-5G, WiFi-6E, or above. In some embodiments, the omnidirectional antenna 20 and the directional antenna 30 may be disposed within the housing 10 to prevent interference from the external environment. In other embodiments, the omnidirectional antenna 20 and the directional antenna 30 may be partially disposed inside the housing 10 and partially disposed outside the housing 10, or all disposed outside the housing 10; no specific limitation is made in this embodiment.

[0113] In some embodiments, the omnidirectional antenna 20 is fixed to the housing 10. The omnidirectional antenna 20 has a central axis O, which coincides with the central axis of the radiation pattern of the omnidirectional antenna 20 in three-dimensional space. See also Figure 2 , Figure 2 for Figure 1 The diagram shows the radiation pattern of the omnidirectional antenna 20 within the wireless router 100 in three-dimensional space. The radiation pattern of the omnidirectional antenna 20 is approximately "apple-shaped," with its central axis O coinciding with the central axis of the apple-shaped radiation pattern. In some embodiments, the central axis O extends along the Z-axis, thus enabling the omnidirectional antenna 20 to radiate uniformly at 360° in the XY plane. When the wireless router 100 is used in a home, the omnidirectional antenna 20 can achieve short-range coverage within a 360° range in the XY plane.

[0114] Please see Figure 3 , Figure 3 for Figure 1 The diagram shows the radiation pattern of the directional antenna 30 inside the wireless router 100 in three-dimensional space. Figure 3 It can be seen that the directional antenna 30 is in a certain direction (e.g., Figure 3 The directional antenna 30 has a particularly strong ability to transmit and receive signals along the X-axis (in the X-axis direction), while its ability to transmit and receive signals in other directions is weak or zero. The direction in which the directional antenna 30 has the strongest signal transmission and reception capability is hereinafter referred to as the beam pointing of the directional antenna 30. The directional antenna 30 has a relatively high gain (8dBi~12dBi) and superior anti-interference capability. Furthermore, compared to the omnidirectional antenna 20, the directional antenna 30 has a longer coverage distance. For an example, please refer to [link to example]. Figure 4 , Figure 4 for Figure 1 The diagram shows the coverage area of ​​the omnidirectional antenna 20 and directional antenna 30 when the wireless router 100 is used in a large single-level residential house. Specifically, Figure 4 (a) in the diagram is a schematic diagram of the coverage area of ​​the omnidirectional antenna 20. Figure 4 (b) in the diagram illustrates one coverage range of the directional antenna 30. In this example, the omnidirectional antenna 20 has a shorter coverage distance, only covering the relatively nearby target device 01, and not the relatively distant target device 02. The directional antenna 30 has a longer coverage distance, covering both the nearby target device 01 and the relatively distant target device 02. Therefore, compared to the omnidirectional antenna 20, the directional antenna 30 has a longer coverage distance, capable of covering target devices at medium to long distances.

[0115] It should be noted that the target device described in this application refers to an electronic device that needs to establish a connection with the wireless router 100 to access the Internet. Specifically, the target device includes, but is not limited to, personal computers, wireless routers, portable computer devices, mobile terminal devices (such as PDAs, handheld computers, mobile phones or smartphones, etc.), smart wearable devices, or smart home devices (such as smart TVs, smart refrigerators, air conditioners, washing machines, air purifiers, etc.). Among them, smart wearable devices include, but are not limited to, wristbands, watches, augmented reality (AR) glasses, AR headsets, virtual reality (VR) glasses, or VR headsets, etc.

[0116] contrast Figure 2 and Figure 3As can be seen, compared to the omnidirectional antenna 20, the beam of the directional antenna 30 is concentrated in one or more directions, therefore the coverage angle of the directional antenna 30 is narrower. Based on this, in order for the omnidirectional antenna 20 to serve target devices in different locations, please refer to [reference needed]. Figure 1 The wireless router also includes a drive unit 40, which drives the directional antenna 30 to rotate in order to adjust the beam direction of the directional antenna 30 so that the directional antenna 30 can serve target devices in different locations.

[0117] In some embodiments, please continue reading Figure 1 The driving device 40 is used to drive the directional antenna 30 to rotate about the first axis L1. Optionally, the first axis L1 is parallel to the central axis O of the omnidirectional antenna 20. In some other alternative embodiments, the first axis L1 may also be perpendicular to or intersect with the central axis O of the omnidirectional antenna 20. The following embodiments are described based on the premise that the first axis L1 is parallel to the central axis O of the omnidirectional antenna 20, which should not be considered as a special limitation of this application. Since the central axis O of the omnidirectional antenna 20 extends along the height direction (i.e., the Z-axis direction) of the wireless router 100, the first axis L1 also extends along the height direction of the wireless router 100. In this way, the driving device 40 can adjust the beam pointing of the directional antenna 30 in the XY plane so that the directional antenna 30 can serve target devices at different locations in the XY plane. Therefore, the wireless router 100 can be adapted to large single-level residential house structures.

[0118] The drive unit 40 has various structural forms. For examples, please refer to [link to example]. Figure 5 , Figure 5 for Figure 1 The diagram shows a structural schematic of a drive device 40 in the wireless router 100. In this example, the drive device 40 includes a rotary motor 41. The rotary motor 41 can be a motor with a speed reducer or a motor without a speed reducer. The types of rotary motor 41 include, but are not limited to, servo motors, stepper motors, torque motors, switched reluctance motors, and brushless DC motors. The central axis of the output shaft of the rotary motor 41 is collinear with the first axis L1, and the output shaft of the rotary motor 41 is fixedly connected to the directional antenna 30.

[0119] In this way, when the rotary motor 41 rotates, it can drive the directional antenna 30 to rotate around the first axis L1. This drive device 40 has a simple structure and low cost. Moreover, the rotary motor 41 is directly connected to the directional antenna 30 without the need for a transmission device, so the transmission efficiency is high and the mechanical energy loss is small.

[0120] For another example, please refer to Figure 6 , Figure 6 for Figure 1The diagram shows another type of drive device 40 in the wireless router 100. In this example, the drive device 40 includes a rotary motor 41, a driving bevel gear 42, and a driven bevel gear 43. The rotary motor 41 can be a motor with a speed reducer or a motor without a speed reducer. The types of rotary motor 41 include, but are not limited to, servo motors, stepper motors, torque motors, switched reluctance motors, and brushless DC motors. The output shaft of the rotary motor 41 is connected to the driving bevel gear 42 to drive the driving bevel gear 42 to rotate. The driven bevel gear 43 meshes with the driving bevel gear 42 for transmission. The central axis of the driven bevel gear 43 is collinear with the first axis L1, and the driven bevel gear 43 is fixedly connected to the directional antenna 30.

[0121] In this way, when the rotary motor 41 rotates, the driving bevel gear 42 and the driven bevel gear 43 mesh and drive the directional antenna 30 to rotate around the first axis L1. The gear transmission has high precision, high transmission efficiency, and low loss. At the same time, the transmission path is turned by the bevel gear transmission, which allows the rotary motor 41 to be installed on one side of the first axis L1, thereby reducing the height occupied by the drive device 40 in the Z-axis direction.

[0122] For another example, please refer to Figure 7 , Figure 7 for Figure 1 The diagram shows a structural schematic of another type of drive device 40 in the wireless router. In this example, the drive device 40 includes a rotary motor 41, a drive gear 44, and an end-face gear disk 45. The rotary motor 41 can be a motor with a reducer or a motor without a reducer. The types of rotary motor 41 include, but are not limited to, servo motors, stepper motors, torque motors, switched reluctance motors, and brushless DC motors. The output shaft of the rotary motor 41 is connected to the drive gear 44 to drive the drive gear 44 to rotate. The drive gear 44 meshes with the end-face gear disk 45 for transmission. The central axis of the end-face gear disk 45 is collinear with the first axis L1, and the end-face gear disk 45 is fixedly connected to the directional antenna 30.

[0123] In this way, when the rotary motor 41 rotates, the drive gear 44 and the end face gear disk 45 mesh and drive the directional antenna 30 to rotate around the first axis L1. The gear transmission has high precision, high transmission efficiency, and low loss. At the same time, through the transmission between the drive gear and the end face gear disk, on the one hand, the transmission path is reversed, allowing the rotary motor 41 to be installed on one side of the first axis L1, thereby reducing the height occupied by the drive device 40 in the Z-axis direction. On the other hand, the larger radius of the end face gear disk increases the distance between the rotary motor 41 and the directional antenna 30, allowing the rotary motor 41 to be installed in an area with sufficient space inside the wireless router.

[0124] It should be noted that, in addition to the aforementioned rotary motor and the combination of rotary motor and gear transmission device, the drive device 40 may also include a combination of rotary motor and transmission device other than gear transmission device, such as belt transmission device, pneumatic transmission device, and hydraulic transmission device. This application does not make specific limitations in this regard.

[0125] In some embodiments, please refer to Figure 8 , Figure 8 This is a schematic diagram of the structure of a wireless router 100 provided in some embodiments of this application. Figure 8 The wireless router shown is Figure 1 The differences between the wireless routers shown are: Figure 8 In the wireless router shown, the driving device 40, in addition to driving the directional antenna 30 to rotate around the first axis L1, also drives the directional antenna 30 to rotate around the second axis L2. The second axis L2 is perpendicular to the first axis L1 and also perpendicular to the beam direction of the directional antenna 30. Since the beam direction of the directional antenna 30 changes when it rotates around the first axis L1, the extension direction of the second axis L2 also changes accordingly. In this way, the driving device 40 can adjust the beam direction of the directional antenna 30 within the XYZ three-dimensional space, enabling the directional antenna 30 to serve target devices at different locations within the XYZ three-dimensional space. Therefore, the wireless router 100 is suitable for house structures such as villas and duplexes.

[0126] In the above embodiments, the drive device 40 can have various structural forms. For example, the drive device 40 can be a ball joint structure that can move in any direction in the XYZ three-dimensional space.

[0127] For another example, please refer to Figure 9 , Figure 9 for Figure 8 The diagram shows a structural schematic of a driving device 40 in the wireless router 100. In this example, the driving device 40 includes a first driving device 40a and a second driving device 40b. The first driving device 40a is used to drive the directional antenna 30 to rotate around a first axis L1. The structural form of the first driving device 40a can be similar to... Figure 1The structure of the driving device 40 in the wireless router 100 shown is the same, and will not be described in detail here. The second driving device 40b is connected between the first driving device 40a and the directional antenna 30. While driving the directional antenna 30 to rotate around the first axis L1, the first driving device 40a also drives the second driving device 40b to rotate together with the directional antenna 30 around the first axis L1. The second driving device 40b drives the directional antenna 30 to rotate around the second axis L2. In this way, by using the first driving device 40a and the second driving device 40b to drive the directional antenna 30 to rotate around the first axis L1 and the second axis L2 respectively, the structural manufacturing difficulty and cost of the driving device can be reduced, and the driving processes of the two driving devices are independent of each other, ensuring driving accuracy.

[0128] In the above embodiments, the structure of the second drive device 40b includes, but is not limited to, a rotary motor, and a combination of a rotary motor with a belt drive, a pneumatic drive, a hydraulic drive, and a gear drive.

[0129] For an example, please refer to Figure 10 , Figure 10 for Figure 9 A schematic diagram of a specific structure of the driving device 40 is shown. In this embodiment, the first driving device 40a and... Figure 5 The structure of the drive device 40 shown is the same, and will not be described in detail here. The second drive device 40b includes a rotary motor 40b1. The stator of the rotary motor 40b1 is fixed relative to the output shaft of the rotary motor of the first drive device 40a. The first drive device 40a drives the rotary motor 40b1 to rotate around the first axis L1. Based on this, the directional antenna 30 is fixed to the rotor of the rotary motor 40b1, and the rotary motor 40b1 drives the directional antenna 30 to rotate around the second axis L2. This second drive device 40b has a simple structure, high transmission efficiency, and low mechanical energy loss.

[0130] For another example, please refer to Figure 11 , Figure 11 for Figure 9 This is another specific structural schematic diagram of the driving device 40 shown. In this embodiment, the first driving device 40a and... Figure 7 The structure of the drive device 40 shown is the same, and will not be described in detail here. The second drive device 40b also includes a rotary motor 40b1. The stator of the rotary motor 40b1 is fixed relative to the gear plate on the middle end face of the first drive device 40a. The first drive device 40a drives the rotary motor 40b1 to rotate around the first axis L1. Based on this, the directional antenna 30 is fixed to the rotor of the rotary motor 40b1, and the rotary motor 40b1 drives the directional antenna 30 to rotate around the second axis L2. This second drive device 40b has a simple structure, high transmission efficiency, and low mechanical energy loss.

[0131] The above embodiments have described various structural forms of the driving device 40. Of course, the driving device 40 can also have other structural forms, as long as it can drive the directional antenna 30 to rotate, so as to achieve the purpose of adjusting the beam direction of the directional antenna 30.

[0132] In some embodiments, the directional antenna 30 includes a radiator and a reflector. Rotation of at least one of the radiator and the reflector changes the beam pointing of the directional antenna 30. Furthermore, a drive device 40 can be connected to the radiator and / or the reflector of the directional antenna 30 to drive the radiator and / or the reflector to rotate, thereby changing the aperture orientation of the radiator and the reflection direction of the reflector, thus achieving the purpose of adjusting the beam pointing of the directional antenna 30.

[0133] In this embodiment, a physical mechanical structure (i.e., a driving device 40) is used to drive the directional antenna 30 to rotate, thereby adjusting the beam pointing of the directional antenna 30. Compared to traditional circuit adjustment methods (such as beamforming), the physical mechanical adjustment method has higher antenna aperture utilization, a wider beam, and higher maximum gain. Furthermore, the control method is simple, the control circuit structure is simple, and it allows the directional antenna 30 to cover more sectors. For example, a directional antenna adjusted by a transmission circuit typically covers 3-4 sectors, while the directional antenna adjusted by the physical mechanical structure in this embodiment can cover far more than 4 sectors, depending on the stepping accuracy of the driving device 40.

[0134] In this embodiment, while using the omnidirectional antenna 20 to meet the access needs of ordinary devices, the directional antenna with higher gain and adjustable beam direction can meet the access needs of medium- and long-distance weak field devices and high-speed devices, thereby improving the applicability of the wireless router 100.

[0135] In the process of adjusting the beam direction of the directional antenna 30 through the driving device 40 to enable the directional antenna 30 to cover the target device, a beam lookup table can be established in some embodiments to simplify control. The beam lookup table includes a set of beams composed of the directional antenna 30 when it rotates to multiple different positions under the drive of the driving device 40. In other words, the beam lookup table includes a set of multiple beams, which are the beams of the directional antenna 30 when it rotates to multiple different positions under the drive of the driving device 40. Based on this, the driving device 40 can refer to the beam lookup table to drive the directional antenna 30 to rotate so that the beam direction of the directional antenna 30 coincides with the direction of the target beam in the beam lookup table. The target beam is one of the multiple beams included in the beam lookup table, and the target beam can cover the target device.

[0136] In this way, when the directional antenna 30 is driven to rotate by the drive device 40, the directional antenna 30 can be adjusted to cover the target device simply by making the beam pointing of the directional antenna 30 coincide with the pointing of the target beam in a limited number of beams in the beam lookup table. It is not necessary to traverse all the directions that the directional antenna 30 can rotate to under the drive of the drive device 40. Therefore, the control difficulty is low and the power consumption and time delay are small.

[0137] In some embodiments, when the driving device 40 is used to drive the directional antenna 30 to rotate about the first axis L1, a plurality of beams in the beam lookup table form a plurality of beam subsets arranged circumferentially along the first axis L1, each beam subset including at least a first beam a pointing perpendicular to the first axis L1. See also Figure 12 , Figure 12 This is a schematic diagram of the structure of the first beam a of multiple beam subsets provided in some embodiments of this application. The first beam a of these multiple beam subsets represents the beams of the directional antenna 30 when it rotates around the first axis L1 to multiple different positions under the drive of the driving device 40. In this way, when the directional antenna 30 rotates until its beam direction coincides with the direction of the multiple first beams a, it can cover target devices in the XY plane, making the wireless router suitable for large, single-story house structures.

[0138] Based on the above embodiments, in order to enable the directional antenna 30 to cover target devices at different locations in the XY plane, in some embodiments, please continue to refer to... Figure 12 Along the circumferential direction w1 of the first axis L1, the included angle α between the first beams a in two adjacent beam sub-sets is greater than or equal to the step accuracy angle driven by the driving device 40 around the first axis L1, and less than or equal to the first beam angle of the directional antenna 30.

[0139] In this context, the angle α between the first beam a in two adjacent beam subsets refers to the angle between the maximum gain directions (i.e., beam pointing directions) of the two first beams a.

[0140] In addition, the step accuracy angle of the drive device 40 driving around the first axis L1 refers to the minimum angle of the drive device 40 driving around the first axis L1, which is greater than 0°.

[0141] Furthermore, the first beam angle refers to the angle between two directions on either side of the maximum radiation direction, within a plane perpendicular to the first axis L1 (i.e., the XY plane), where the radiated power decreases by a first preset threshold, when the beam of the directional antenna 30 is perpendicular to the first axis L1. The first preset threshold can be 2dB, 3dB, 4dB, 5dB, etc., and is not specifically limited here. This first preset threshold can be selected according to actual needs. For an example, please refer to [link / reference]. Figure 13 , Figure 13This is a schematic diagram of the first beam angle α of the directional antenna 30 in a wireless router 100 provided in some embodiments of this application. The first beam angle of the directional antenna 30 refers to the angle θ between two directions D2 and D3 located on both sides of the maximum radiation direction D1 in the XY plane, where the radiated power decreases by a first preset threshold (e.g., 3dB).

[0142] For example, when the angle α between the first beams a in two adjacent beam subsets is 20°, there are 18 beam subsets within a 360° range around the first axis L1. When the angle α between the first beams a in two adjacent beam subsets is 45°, there are 8 beam subsets within a 360° range around the first axis L1. When the angle α between the first beams a in two adjacent beam subsets is 90°, there are 4 beam subsets within a 360° range around the first axis L1.

[0143] In this way, the beam lookup table is complete within a 360° range along the first axis L1, and the beam pointing of the directional antenna 30 can be adjusted to multiple positions within a 360° range along the first axis L1, so that the directional antenna 30 can cover the target device at any position in the XY plane.

[0144] In some embodiments, please refer back to the reference. Figure 12 Along the circumferential direction w1 of the first axis L1, the included angle α between the first beams a in two adjacent beam subsets is equal to the first beam angle of the directional antenna 30. This results in a smaller number of beams in the beam lookup table, lower control complexity, and lower power consumption and latency.

[0145] Based on the above embodiments, when the driving device 40 is used not only to drive the directional antenna 30 to rotate around the first axis L1, but also to drive the directional antenna 30 to rotate around the second axis L2, the multiple beams in the beam lookup table form multiple beam subsets arranged circumferentially along the first axis L1. The beam subsets include multiple beams arranged circumferentially along the second axis L2, and the first beam a is one of the multiple beams.

[0146] Since the second axis L2 is perpendicular to the beam direction of the directional antenna 30, and the beam direction of the directional antenna 30 changes when it rotates around the first axis L1, the extension direction of the second axis L2 also changes with the change in the beam direction of the directional antenna 30. In this way, multiple beams from different beam subsets are arranged circumferentially around the second axis with different extension directions.

[0147] For examples, please refer to Figure 14 , Figure 14This is a schematic diagram of the structure of a beam lookup table provided in some embodiments of this application. The beam lookup table includes multiple beam subsets arranged circumferentially along a first axis L1. These multiple beam subsets include beam subset C1 and beam subset C2. Both beam subset C1 and beam subset C2 include a first beam a pointing perpendicular to the first axis L1. When the directional antenna 30 is driven to rotate by the driving device 40 so that the beam pointing of the directional antenna 30 coincides with the first beam a in beam subset C1 and the first beam a in beam subset C2, the second axis L2 is axis L21 and axis L22, respectively, and the extension directions of axis L21 and axis L22 are different. Based on this, the multiple beams in beam subset C1 are arranged circumferentially around axis L21, and the multiple beams in beam subset C2 are arranged circumferentially along axis L22. That is, the multiple beams in beam subset C1 and the multiple beams in beam subset C2 are arranged circumferentially along the second axis with different extension directions.

[0148] In this way, multiple beams in the beam lookup table are distributed within the XYZ three-dimensional space. When the directional antenna 30 rotates until the beam direction coincides with the direction of multiple beams within the XYZ three-dimensional space, it can cover the target device within the XYZ three-dimensional space. The wireless router can be applied to house structures such as villas and duplexes.

[0149] Based on the above embodiments, in order to enable the directional antenna 30 to cover target devices at different locations within the XYZ three-dimensional space, in some embodiments, please continue to refer to... Figure 14 Along the circumferential direction w2 of the second axis L2, the included angle β between two adjacent beams in the beam subset is greater than or equal to the step accuracy angle driven by the drive device 40 around the second axis L2, and less than or equal to the second beam angle of the directional antenna 30.

[0150] In this context, the angle β between two adjacent beams within a beam subset refers to the angle between the maximum gain directions (i.e., beam directions) of the two beams.

[0151] In addition, the step accuracy angle of the drive device 40 driving around the second axis L2 refers to the minimum angle of the drive device 40 driving around the second axis L2, which is greater than 0°.

[0152] Furthermore, the second beam angle refers to the angle between two directions on either side of the maximum radiation direction, within a plane perpendicular to the second axis L2 (e.g., the XZ plane), when the beam of the directional antenna 30 is perpendicular to the first axis L1, and the radiated power decreases by a second preset threshold. The second preset threshold can be 2dB, 3dB, 4dB, 5dB, etc., and can be equal to or different from the first preset threshold. No specific limitation is made here; the second preset threshold can be selected according to actual needs. For an example, please refer to [link / reference]. Figure 15 , Figure 15 This is a schematic diagram of the second beam angle of the directional antenna 30 in a wireless router 100 provided in some embodiments of this application. The second beam angle of the directional antenna 30 refers to the angle γ between two directions D5 and D6 located on both sides of the maximum radiation direction D4 in the XZ plane, where the radiated power decreases by a second preset threshold (e.g., 3dB).

[0153] In this way, the beam lookup table is complete in the XYZ three-dimensional space, and the beam pointing of the directional antenna 30 can be adjusted to multiple positions in the XYZ three-dimensional space so that the directional antenna 30 can cover the target device at any position in the XYZ three-dimensional space.

[0154] In some embodiments, along the circumferential direction w2 of the second axis L2, the included angle β between two adjacent beams in the beam subset is equal to the second beam angle of the directional antenna 30. This results in a smaller number of beams in the beam lookup table, lower control complexity, and lower power consumption and latency.

[0155] It should be noted that the structure of the beam set in the beam lookup table can be, in addition to being, [other possible forms]. Figure 12 and Figure 14 Besides the structural form shown, other structural forms are also possible. For example, [the structure could be derived from...]. Figure 12 The beams are composed of beams located within a circumferential 180° range along the first axis L1. For example, [the beams are composed of...]. Figure 14 The beams are composed of beams located within a circumferential range of 180° on the first axis L1 and within a circumferential range of 90° on the second axis L2. This application embodiment does not specifically limit this.

[0156] Based on the descriptions of the above embodiments, the beam lookup table includes multiple beams. In order to determine the target beam among these multiple beams, the following two embodiments can be adopted, namely Embodiment 1 and Embodiment 2.

[0157] Example 1: Please refer to Figure 16 , Figure 16 This is a schematic diagram of the structure of a wireless router 100 provided in some embodiments of this application. In this embodiment, the wireless router 100 further includes a controller 50 and a detection system 60.

[0158] The controller 50 may include a processor or necessary logic circuitry. The processor may be a baseband processor, digital signal processor, microprocessor, or central processing unit, etc. The controller 50 is electrically connected to the drive device 40, and is used to control the drive device 40 to drive the directional antenna 30 to rotate sequentially to multiple positions, so that the beam pointing of the directional antenna 30 coincides with the pointing of multiple beams in a beam lookup table. These multiple beams may be all beams in the beam lookup table, or only a portion of the beams in the beam lookup table; no specific limitation is made here.

[0159] The detection system 60 is used to detect the signal quality received by the directional antenna 30 from the target device when the beam pointing of the directional antenna 30 coincides with the pointing of multiple beams in the beam lookup table. This signal quality can be evaluated by at least one of the following metrics: Received Signal Strength Indication (RSSI), Error Rate (PER), Throughput, and Channel Status Information (CSI). When the signal quality is evaluated by a combination of these metrics, the multiple metrics can be weighted to obtain a single composite metric for evaluation, or they can be evaluated separately; no specific limitation is made here.

[0160] The controller 50 is electrically connected to the detection system 60. The controller 50 is also used to determine the target beam in the beam lookup table based on the multiple signal quality values ​​detected by the detection system 60. Optionally, when the controller 50 determines that the signal quality is optimal, the beam in the beam lookup table that coincides with the beam direction of the directional antenna 30 is the target beam.

[0161] This wireless router has a simple structure and does not require a special positioning device, thus its cost is low.

[0162] Based on the above embodiments, the controller 50 is also used to control the drive device 40 to drive the directional antenna 30 to rotate, so that the beam pointing of the directional antenna 30 coincides with the pointing of the target beam in the beam lookup table. This achieves automated control, simplifies control complexity, and ensures drive accuracy.

[0163] Example 2: Please refer to Figure 17 , Figure 17 This is a schematic diagram of the structure of a wireless router 100 provided in some embodiments of this application. In this embodiment, it also includes a positioning device 70 and a controller 50.

[0164] The positioning device 70 includes, but is not limited to, an ultra-wideband (UWB) antenna. The positioning device 70 is used to acquire the location information of the target device. The controller 50 is electrically connected to the positioning device 70, and the controller 50 is used to determine the target beam in the beam lookup table based on the location information acquired by the positioning device 70. Optionally, the controller 50 determines the beam in the beam lookup table with the smallest angle between its beam direction and the target location relative to the wireless router's position as the target beam. This wireless router does not need to poll to find the target beam, therefore its response speed is faster and its latency is shorter.

[0165] Based on the above embodiments, the controller 50 is also used to control the drive device 40 to drive the directional antenna 30 to rotate, so that the beam pointing of the directional antenna 30 coincides with the pointing of the target beam in the beam lookup table. This achieves automated control, simplifies control complexity, and ensures drive accuracy.

[0166] The above embodiments illustrate the case where both the number of omnidirectional antennas 20 and the number of directional antennas 30 is one. Of course, the number of omnidirectional antennas 20 and the number of directional antennas 30 can also be multiple, or the number of omnidirectional antennas 20 can be one and the number of directional antennas 30 can be multiple, or the number of omnidirectional antennas 20 can be multiple and the number of directional antennas 30 can be one. That is, the number of omnidirectional antennas 20 is at least one, and the number of directional antennas 30 is at least one.

[0167] When there are multiple omnidirectional antennas 20, the transmission and reception of multiple different channel signals can be supported by these multiple omnidirectional antennas 20, thereby further improving the versatility of the wireless router 100.

[0168] When there are multiple directional antennas 30, multiple users can be connected to the downlink concurrently using these multiple directional antennas 30.

[0169] By combining different numbers of omnidirectional antennas 20 and different numbers of directional antennas 30, wireless routers 100 of different specifications can be obtained. The specifications of the wireless router 100 can be MIMO 2x2, MIMO 3x3, and MIMO 4x4. When the wireless router 100 is MIMO 2x2, the total number of omnidirectional antennas 20 and directional antennas 30 is 2; specifically, there is 1 omnidirectional antenna 20 and 1 directional antenna 30. When the wireless router 100 is MIMO 3x3, the total number of omnidirectional antennas 20 and directional antennas 30 is 3; specifically, there is 1 omnidirectional antenna 20 and 2 directional antennas 30; or, there are 2 omnidirectional antennas 20 and 1 directional antenna 30. When the wireless router 100 is configured for MIMO 4x4, the total number of omnidirectional antennas 20 and directional antennas 30 is four. Specifically, there may be one omnidirectional antenna 20 and three directional antennas 30; or two omnidirectional antennas 20 and two directional antennas 30; or three omnidirectional antennas 20 and one directional antenna 30. The specifications of the wireless router 100, and the number of omnidirectional antennas 20 and directional antennas 30 under different specifications, are recorded in Table 1.

[0170] Table 1

[0171]

[0172] It should be noted that Table 1 only provides examples of wireless router 100 with MIMO 2x2, MIMO 3x3, and MIMO 4x4 specifications. Of course, the specifications of wireless router 100 can also be MIMO 5x5, MIMO 6x6, etc., that is, the total number of omnidirectional antennas 20 and directional antennas 30 in wireless router 100 is 5 or 6, etc.

[0173] To output or receive radio frequency signals from omnidirectional and directional antennas, please refer to [link to relevant documentation]. Figure 18 , Figure 18This is an internal circuit diagram of a wireless router 100 provided in some embodiments of this application. The wireless router 100 also includes a radio frequency transceiver system 80, which is used to transmit and receive signals from the at least one omnidirectional antenna 20 and the at least one directional antenna 30. Specifically, the radio frequency transceiver system 80 has multiple signal output terminals 80a, which are electrically connected to the at least one omnidirectional antenna 20 and the at least one directional antenna 30, respectively. The radio frequency transceiver system 80 generates radio frequency signals and outputs these signals to the at least one omnidirectional antenna 20 and the at least one directional antenna 30 via the multiple signal output terminals 80a, thereby transmitting signals. Simultaneously, the radio frequency transceiver system 80 can also receive signals received by the at least one omnidirectional antenna 20 and the at least one directional antenna 30 via the multiple signal output terminals 80a, thereby receiving signals.

[0174] The radio frequency transceiver system 80 has various structural forms. For some embodiments, please refer to [link / reference needed]. Figure 19 , Figure 19 for Figure 18 The diagram shows the structure of the radio frequency transceiver system 80 within the wireless router 100. The radio frequency transceiver system 80 includes multiple radio frequency transceiver links (also called radio frequency transceivers or TRx) 81. The number of multiple radio frequency transceiver links 81 is the same as the number of multiple signal output terminals 80a mentioned above, and each radio frequency transceiver link 81 has one signal output terminal 80a.

[0175] In some embodiments, please continue reading Figure 19 The radio frequency (RF) transceiver link 81 may include a duplexer 811, a transmit path 812, and a receive path 813. Specifically, the duplexer 811 connects the transmit path 812 and the receive path 813 to the signal output terminal 80a. A processing circuit 82 for generating transmit signals or processing receive signals may be connected to the back end of the RF transceiver link 81. This processing circuit 82 may include a processor or necessary logic circuitry for performing baseband signal processing or digital signal processing. The processor may be a baseband processor, a digital signal processor, a microprocessor, or a central processing unit, etc. The processing circuit 82 may be included within the RF transceiver link 81 or may be independent of the RF transceiver link 81.

[0176] The duplexer 811 can be a frequency division duplexer or a time division duplexer, used to couple the transmitted signal from the transmit path 812 to the signal output terminal 80a, and to couple the received signal from the signal output terminal 80a to the receive path 813. Specifically, the duplexer 811 can be one or more combinations of the following: a single-pole multi-throw switch, a circulator, and a filter.

[0177] The transmit path 812 is used to receive a transmit signal from the processing circuit 82 at the back end, process the transmit signal, and transmit the transmit signal to the signal output terminal 80a through the duplexer 811. Specifically, the transmit path 812 may include a power amplifier and / or an upmixer. The power amplifier is used to amplify the transmit signal transmitted in the transmit path 812. The upmixer, also called a modulator, is used to convert the frequency of the transmit signal transmitted in the transmit path 812 from a first frequency to a second frequency. The first frequency is lower than the second frequency. Typically, the upmixer is used to modulate a baseband signal or intermediate frequency signal into a radio frequency signal. If the transmit path 812 includes a power amplifier and an upmixer, the input terminal of the mixer can be connected to the processing circuit 82, the output terminal of the mixer can be connected to the input terminal of the power amplifier, and the output terminal of the power amplifier can be connected to one end of the duplexer 811. Alternatively, the positions of the power amplifier and the upmixer can be interchanged.

[0178] The receiving path 813 is used to process and transmit the received signal from the signal output terminal 80a to the back-end processing circuit 82. The receiving path 813 may include a low-noise amplifier (LNA) and a down-mixer. The LNA amplifies the weak signal received from the signal output terminal 80a and reduces noise interference during the amplification process. The down-mixer, also called a demodulator, is used to convert the frequency of the received signal transmitted in the receiving path 813 from a third frequency to a fourth frequency, where the third frequency is higher than the fourth frequency. Typically, the down-mixer is used to demodulate the radio frequency signal into a baseband signal or an intermediate frequency signal. The positions of the down-mixer and LNA in the receiving path 813 can be interchanged.

[0179] The number of signal output terminals 80a of the RF transceiver system 80 can be equal to the sum of the number of omnidirectional antennas 20 and the number of directional antennas 30. For an example, please refer to [link to example]. Figure 18 and Figure 19 There are two omnidirectional antennas 20 and two directional antennas 30, so the total number of omnidirectional antennas 20 and directional antennas 30 is four. The number of signal output terminals 80a in the RF transceiver system 80 is also four. Based on this, in the RF transceiver system 80, some signal output terminals 80a are electrically connected to the omnidirectional antennas 20 in a one-to-one correspondence, and other signal output terminals 80a are electrically connected to the directional antennas 30 in a one-to-one correspondence. For an example, please continue reading. Figure 18 and Figure 19 Of the four signal output terminals 80a of the radio frequency transceiver system 80, two signal output terminals 80a are electrically connected to two omnidirectional antennas 20, respectively, and the other two signal output terminals 80a are electrically connected to two directional antennas 30, respectively. In this way, signal transmission and reception of the omnidirectional antennas 20 and directional antennas 30 in the wireless router can be realized simultaneously.

[0180] In some other embodiments, while keeping the number of signal output terminals 80a of the RF transceiver system 80 unchanged, the number of omnidirectional antennas 20 and / or directional antennas 30 can be increased so that the sum of the number of omnidirectional antennas 20 and the number of directional antennas 30 is greater than the number of signal output terminals 80a of the RF transceiver system 80. Based on this, please refer to... Figure 20 , Figure 20 The following is an internal circuit diagram of a wireless router 100 provided in some embodiments of this application. A switching switch 90 is also provided between the signal output terminal 80a of the radio frequency transceiver system 80 and the omnidirectional antenna 20 and the directional antenna 30. The switching switch 90 is used to select that the multiple signal output terminals 80a of the radio frequency transceiver system 80 are electrically connected to any multiple antennas of the omnidirectional antenna 20 and the directional antenna 30, so that the wireless router can switch between multiple usage scenarios.

[0181] For example, while keeping the number of signal output terminals 80a of the RF transceiver system 80 unchanged, only the number of omnidirectional antennas 20 is increased so that the number of omnidirectional antennas 20 is equal to the number of signal output terminals 80a of the RF transceiver system 80, and the sum of the number of omnidirectional antennas 20 and the number of directional antennas 30 is greater than the number of signal output terminals 80a of the RF transceiver system 80. Specifically, the number of omnidirectional antennas 20 and the number of directional antennas 30 in the MIMO 2X2, MIMO 3X3, and MIMO 4X4 wireless routers 100 are listed in Table 2 below.

[0182] Table 2

[0183]

[0184] In a MIMO 2x2 wireless router, the radio frequency transceiver system 80 has two signal output terminals 80a. These two signal output terminals 80a can be electrically connected to two omnidirectional antennas 20 via a switch 90, allowing ordinary devices to simultaneously transmit and receive signals from two channels. Alternatively, the two signal output terminals 80a can be electrically connected to one omnidirectional antenna 20 and one directional antenna 30 via the switch 90. In this case, while still allowing ordinary devices to access the network, the wireless router 100 can also serve medium- to long-distance devices and high-speed devices. Thus, the wireless router has two usage scenarios, which can be switched between using the switch 90.

[0185] In a MIMO 3x3 wireless router, the RF transceiver system 80 has three signal output terminals 80a. These three output terminals 80a can be electrically connected to three omnidirectional antennas 20 via a switch 90, allowing ordinary devices to simultaneously transmit and receive signals across three channels. Alternatively, the three output terminals 80a can be electrically connected to one omnidirectional antenna 20 and two directional antennas 30 via the switch 90, allowing the wireless router 100 to simultaneously serve two medium-to-long-range or high-speed devices while still allowing ordinary devices to access the network. Another option is to connect the three output terminals 80a to two omnidirectional antennas 20 and one directional antenna 30 via the switch 90, allowing ordinary devices to simultaneously transmit and receive signals across two channels while still serving one medium-to-long-range or high-speed device. Thus, the wireless router offers three usage scenarios, which can be switched between using the switch 90.

[0186] In a MIMO 4x4 wireless router, the RF transceiver system 80 has four signal output terminals 80a. These four signal output terminals 80a can be electrically connected to four omnidirectional antennas 20 via a switch 90, allowing ordinary devices to simultaneously transmit and receive signals across four channels. Alternatively, the four signal output terminals 80a can be electrically connected to one omnidirectional antenna 20 and three directional antennas 30 via the switch 90, allowing the wireless router 100 to simultaneously serve three medium-to-long-range or high-speed devices while still allowing ordinary devices to access the network. Finally, the four signal output terminals 80a can be electrically connected to two omnidirectional antennas 20 and two directional antennas 30 via the switch 90, allowing the wireless router 100 to serve two medium-to-long-range or high-speed devices while still allowing ordinary devices to simultaneously transmit and receive signals across two channels. The four signal output terminals 80a can also be electrically connected to the three omnidirectional antennas 20 and one directional antenna 30 via a switch 90. In this case, while ensuring simultaneous transmission and reception of three channels for ordinary devices, the wireless router 100 can serve one medium-to-long-range or high-speed device. Thus, the wireless router has four usage scenarios, which can be switched between using the switch 90.

[0187] The above embodiments describe the structure of the wireless router 100. The wireless router 100 provided in this application embodiment not only meets the access needs of ordinary users with the help of the omnidirectional antenna 20, but also meets the access needs of medium and long distance devices and high-speed devices with the help of the beam-adjustable directional antenna 30, thereby improving the application versatility of the wireless router 100.

[0188] This application also provides a control method for a wireless router, applicable to the aforementioned wireless router 100. The wireless router 100 includes an omnidirectional antenna 20, a directional antenna 30, and a driving device 40, wherein the driving device 40 is connected to the directional antenna 30. Please refer to [link to relevant documentation]. Figure 21 , Figure 21 The flowchart illustrates a control method for a wireless router provided in some embodiments of this application. The control method includes the following steps S100 to S200.

[0189] Step S100: Obtain the signal quality received by the omnidirectional antenna 20 from the first target device to obtain the first signal quality Q1.

[0190] The first target device is an electronic device within the coverage area of ​​the wireless router. This electronic device includes, but is not limited to, personal computers, wireless routers, portable computer devices, mobile terminal devices (such as PDAs, handheld computers, mobile phones, or smartphones), smart wearable devices, or smart home devices (such as smart TVs, smart refrigerators, air conditioners, washing machines, air purifiers, etc.). Among them, smart wearable devices include, but are not limited to, wristbands, watches, AR glasses, AR helmets, VR glasses, or VR helmets.

[0191] In addition, the first signal quality Q1 can be evaluated by at least one of the following metrics: RSSI, PER, throughput, CSI, etc. When the first signal quality Q1 is evaluated by multiple of these metrics, the multiple metrics can be weighted to obtain a comprehensive metric for evaluation, or they can be evaluated separately; no specific limitation is made here.

[0192] S200: When the first signal quality Q1 is less than the third preset threshold, the directional antenna 30 is driven to rotate by the driving device 40 so that the beam direction of the directional antenna 30 coincides with the direction of the target beam in the beam lookup table, and the target beam can cover the first target device. This switches the beam direction of the directional antenna 30 so that the directional antenna 30 can cover the first target device.

[0193] The drive device 40 is used to drive the directional antenna 30 to rotate, so as to adjust the beam direction of the directional antenna 30 and enable the directional antenna 30 to serve target devices in different locations.

[0194] In this way, while using omnidirectional antennas to meet the access needs of ordinary devices, directional antennas with higher gain and adjustable beam direction can meet the access needs of medium- and long-range devices in weak fields and high-speed devices, thereby improving the versatility of wireless router applications. Furthermore, during the rotation of the directional antenna using a driving device, it is only necessary to align the beam direction of the directional antenna with the target beam direction among a limited number of beams in the beam lookup table to adjust the directional antenna to the position covering the target device. It is not necessary to traverse all the directions the directional antenna can rotate to under the drive of the driving device, thus reducing control difficulty, power consumption, and latency.

[0195] In some embodiments, the drive unit 40 drives the directional antenna 30 to rotate about a first axis L1. Optionally, the first axis is parallel to the central axis O of the omnidirectional antenna 20. Since the central axis O of the omnidirectional antenna 20 typically extends along the height direction (i.e., the Z-axis direction) of the wireless router, the first axis L1 also extends along the height direction of the wireless router. In this way, the drive unit 40 can adjust the beam pointing of the directional antenna 30 in the horizontal plane (i.e., the XY plane) so that the directional antenna 30 can serve target devices at different locations in the horizontal plane, thus making the wireless router suitable for large single-level residential house structures.

[0196] Based on the above embodiments, optionally, the driving device 40 is further configured to drive the directional antenna 30 to rotate around a second axis L2, the second axis L2 being perpendicular to the first axis L1, and also perpendicular to the beam pointing of the directional antenna 30. Since the beam pointing of the directional antenna 30 changes when it rotates around the first axis L1, the extension direction of the second axis L2 also changes accordingly. In this way, the driving device 40 can adjust the beam pointing of the directional antenna 30 within a three-dimensional space, enabling the directional antenna 30 to serve target devices at different locations within the three-dimensional space. Therefore, the wireless router can be applied to house structures such as villas and duplexes.

[0197] The drive device 40 can have various structural forms. Specifically, the drive device 40 may include the aforementioned rotary motor, as well as combinations of rotary motors with gear transmission devices, belt transmission devices, pneumatic transmission devices, hydraulic transmission devices, etc. This application does not make specific limitations in this regard.

[0198] The beam lookup table includes a set of beams formed when the directional antenna 30 rotates to multiple different orientations under the drive of the drive device 40. In other words, the beam lookup table includes a set of multiple beams, which are the beams formed when the directional antenna 30 rotates to multiple different orientations under the drive of the drive device 40.

[0199] When the driving device 40 drives the directional antenna 30 to rotate around the first axis L1, multiple beams in the beam lookup table form multiple beam subsets arranged circumferentially along the first axis L1. Each beam subset includes at least a first beam a pointing perpendicular to the first axis L1. The first beams a of these multiple beam subsets represent the beams of the directional antenna 30 when it rotates around the first axis L1 to multiple different orientations under the drive of the driving device 40. In this way, when the directional antenna 30 rotates until its beam direction coincides with the direction of the multiple first beams a, it can cover target devices in the XY plane, making the wireless router suitable for large single-story house structures.

[0200] To ensure the completeness of the beam lookup table in the XY plane, in some embodiments, along the circumferential direction w1 of the first axis L1, the angle α between the first beams a in two adjacent beam subsets is greater than or equal to the step accuracy angle driven by the driving device 40 around the first axis L1, and less than or equal to the first beam angle of the directional antenna 30. Here, the angle α between the first beams a in two adjacent beam subsets refers to the angle between the maximum gain directions (i.e., beam pointing directions) of the two first beams a. Furthermore, the step accuracy angle driven by the driving device 40 around the first axis L1 refers to the minimum angle driven by the driving device 40 around the first axis L1, which is greater than 0°. Moreover, the first beam angle refers to the angle between two directions located on either side of the maximum radiation direction, where the radiated power decreases by a first preset threshold, in a plane perpendicular to the first axis L1 (i.e., the XY plane), when the beam pointing of the directional antenna 30 is perpendicular to the first axis L1. The first preset threshold can be 2dB, 3dB, 4dB, 5dB, etc., and is not specifically limited here. This first preset threshold can be selected according to actual needs. In this way, the beam lookup table has completeness within a 360° range along the first axis L1, and the beam pointing of the directional antenna 30 can be adjusted to multiple positions within the 360° range along the first axis L1, so that the directional antenna 30 can cover target devices at any location in the XY plane.

[0201] In some embodiments, along the circumferential direction w1 of the first axis L1, the included angle α between the first beams a in two adjacent beam subsets is equal to the first beam angle of the directional antenna 30. This results in a smaller number of beams in the beam lookup table, lower control complexity, and lower power consumption and latency.

[0202] When the driving device 40 is used not only to drive the directional antenna 30 to rotate around the first axis L1, but also to drive the directional antenna 30 to rotate around the second axis L2, multiple beams in the beam lookup table form multiple beam subsets arranged circumferentially along the first axis L1. These beam subsets include multiple beams arranged circumferentially along the second axis L2, with the first beam a being one of these multiple beams. Since the second axis L2 is perpendicular to the beam direction of the directional antenna 30, and the beam direction of the directional antenna 30 changes when it rotates around the first axis L1, the extension direction of the second axis L2 also changes with the change in the beam direction of the directional antenna 30. Thus, multiple beams in different beam subsets are arranged circumferentially around the second axis with different extension directions. In this way, multiple beams in the beam lookup table are distributed within the XYZ three-dimensional space. When the directional antenna 30 rotates until the beam direction coincides with the direction of multiple beams within the XYZ three-dimensional space, it can cover the target device within the XYZ three-dimensional space. The wireless router can be applied to house structures such as villas and duplexes.

[0203] To ensure the completeness of the beam lookup table within the XYZ three-dimensional space, in some embodiments, along the circumferential direction w1 of the first axis L1, the angle α between the first beams a in two adjacent beam subsets is greater than or equal to the step accuracy angle driven by the driving device 40 around the first axis L1, and less than or equal to the first beam angle of the directional antenna 30. Furthermore, along the circumferential direction w2 of the second axis L2, the angle β between two adjacent beams within a beam subset is greater than or equal to the step accuracy angle driven by the driving device 40 around the second axis L2, and less than or equal to the second beam angle of the directional antenna 30. Here, the angle β between two adjacent beams within a beam subset refers to the angle between the maximum gain directions (i.e., beam pointing directions) of the two beams. Additionally, the step accuracy angle driven by the driving device 40 around the second axis L2 refers to the minimum angle driven by the driving device 40 around the second axis L2, which is greater than 0°. Furthermore, the second beam angle refers to the angle between two directions on either side of the maximum radiation direction, where the radiated power decreases by a second preset threshold, within a plane perpendicular to the second axis L2 (e.g., the XZ plane), when the beam pointing of the directional antenna 30 is perpendicular to the first axis L1. The second preset threshold can be 2dB, 3dB, 4dB, 5dB, etc., and can be equal to or different from the first preset threshold. No specific limitation is made here; the second preset threshold can be selected according to actual needs. In this way, the beam lookup table is complete within the XYZ three-dimensional space, and the beam pointing of the directional antenna 30 can be adjusted to multiple positions within the XYZ three-dimensional space, enabling the directional antenna 30 to cover target devices at any location within the XYZ three-dimensional space.

[0204] In some embodiments, along the circumferential direction w1 of the first axis L1, the included angle α between the first beams a in two adjacent beam subsets is equal to the first beam angle of the directional antenna 30. Simultaneously, along the circumferential direction w2 of the second axis L2, the included angle β between two adjacent beams in the beam subsets is equal to the second beam angle of the directional antenna 30. This results in a smaller number of beams in the beam lookup table, lower control complexity, and lower power consumption and latency.

[0205] In some embodiments, please refer to Figure 22 , Figure 22 A flowchart of a control method for a wireless router provided in some embodiments of this application shows that, after step S100, the control method further includes:

[0206] Step S801: Determine whether the quality of the first signal is greater than or equal to the third preset threshold.

[0207] Step S802: When the first signal quality is greater than or equal to the third preset threshold, the omnidirectional antenna 20 covers the first target device. When the first signal quality is greater than or equal to the third preset threshold, while using the omnidirectional antenna to cover the first target device, a directional antenna can also be used to cover the first target device, or the directional antenna can be stopped or used to cover other target devices. This allows for reasonable resource allocation. In some embodiments, step S802 includes: sending parameters to the RF transceiver link of the omnidirectional antenna 20, including but not limited to transmit power and protocol software parameters; entering a standard operating state. After the omnidirectional antenna 20 covers the first target device for a first preset time T1, it can return to step S100 to enter the next cycle. The first preset time T3 can refer to the duration of the standard operating state in step S802. The first preset time T1 includes, but is not limited to, 0.1 seconds (s), 0.2 seconds, 0.3 seconds, etc., and is not specifically limited here.

[0208] In some embodiments, please refer to Figure 23 , Figure 23 A flowchart illustrating a control method for a wireless router provided in some embodiments of this application is provided. The control method further includes:

[0209] Step S300: Obtain the signal quality received by the directional antenna 30 from the first target device to obtain the second signal quality Q2. Based on this, step S200 includes: when the first signal quality Q1 is less than a third preset threshold and the second signal quality Q2 is less than a fourth preset threshold, drive the directional antenna 30 to rotate via the driving device 40 so that the beam direction of the directional antenna 30 coincides with the direction of the target beam in the beam lookup table. In this way, after both the omnidirectional antenna 20 and the directional antenna 30 under the current beam direction fail to cover the first target device, switching the beam direction of the directional antenna 30 can quickly cover the first target device, reducing latency and power consumption in most usage scenarios.

[0210] In the above embodiments, the second signal quality Q2 can also be evaluated by at least one of the following indicators: RSSI, PER, throughput, and CSI. When the second signal quality Q2 is evaluated by a combination of multiple indicators, the multiple indicators can be weighted to obtain a single comprehensive indicator for evaluation, or they can be evaluated separately; no specific limitation is made here. The evaluation indicator for the second signal quality Q2 can be the same as or different from the evaluation indicator for the first signal quality Q1. For example, when the first signal quality Q1 is evaluated by a comprehensive indicator weighted from RSSI, PER, throughput, and CSI, the second signal quality Q2 is also evaluated by a comprehensive indicator weighted from RSSI, PER, throughput, and CSI, and the weighting values ​​of each indicator are the same. In this case, the evaluation indicators for the first signal quality Q1 and the second signal quality Q2 are the same. If the weighting values ​​are different, then the evaluation indicators for the first signal quality Q1 and the second signal quality Q2 are different.

[0211] exist Figure 23 In the control method shown, step S300 can be operated simultaneously with step S100, after step S100, or before step S100; no specific limitation is made here. In some embodiments, step S300 is located after step S100. Specifically, step S300 includes: when the first signal quality is less than a third preset threshold, acquiring the signal quality received by the directional antenna from the first target device. In this way, omnidirectional antenna coverage of the first target device is given priority, and directional antenna coverage is only used when omnidirectional antenna cannot cover the first target device, which can reduce latency and power consumption in most usage scenarios.

[0212] In some embodiments, after step S300, please continue reading Figure 23 The control method also includes the following steps S901 and S902.

[0213] Step S901: Determine whether the quality of the second signal is greater than or equal to the fourth preset threshold.

[0214] Step S902: When the second signal quality is greater than or equal to the fourth preset threshold, the directional antenna pointing to the current beam covers the first target device. In this way, the first target device is covered by the directional antenna pointing to the current beam. While achieving coverage of the first target device, there is no need to rotate the directional antenna, thus resulting in lower latency and power consumption. In some embodiments, step S902 includes: sending parameters to the RF transceiver link of the directional antenna 30, including but not limited to transmit power and protocol software parameters; entering a standard operating state. After the directional antenna 30 covers the first target device for a second preset time T2, it can return to step S100 to enter the next cycle. The second preset time T2 can refer to the duration of the standard operating state in step S902. The second preset time T2 includes, but is not limited to, 0.1s, 0.2s, 0.3s, etc., and is not specifically limited here. Furthermore, the second preset time T2 and the first preset time T1 can be equal or unequal, and are not specifically limited here. Based on this, please continue reading... Figure 23 Step S200 is located after step S901.

[0215] In some embodiments, please continue reading Figure 23 Following step S200, step S1000 is also included. Step S1000: The directional antenna 30, after switching beam direction, covers the first target device to begin operation. Specifically, step S1000 may include: sending parameters to the RF transceiver link of the directional antenna 30, including but not limited to transmit power and protocol software parameters; entering the standard operating state. The step of sending parameters to the RF transceiver link of the directional antenna 30 can be performed before or simultaneously with beam direction switching, in addition to being performed after beam direction switching; no specific limitation is made here. After the directional antenna 30 covers the first target device for a third preset time T3, it can return to step S100 to enter the next cycle. The third preset time T3 may refer to the duration of the standard operating state in step S1000. The third preset time T3 includes, but is not limited to, 0.1s, 0.2s, 0.3s, etc., and no specific limitation is made here. Furthermore, the third preset time T3 may be equal to or unequal to the first preset time T1 and the second preset time T2; no specific limitation is made here. Please refer to [link / reference]. Figure 24 , Figure 24 This is a flowchart of a control method for a wireless router provided in some embodiments of this application. In this embodiment, after step S200, the control method further includes step S1000, in which the directional antenna with switched beam direction covers the first target device to perform the operation.

[0216] In some embodiments, please continue reading Figure 24 Step S300 is executed after a preset time T4 following step S1000. The preset time T4 includes, but is not limited to, 0.1s, 0.2s, and 0.3s, and is not specifically limited here. Based on this, after step S300, the control method also includes steps S903 and S904. Step S903: Determine whether the second signal quality is greater than or equal to a fifth preset threshold; Step S903: When the second signal quality is greater than or equal to the fifth preset threshold, re-enter step S100. In this way, when the signal quality improves, it can be re-determined whether the omnidirectional antenna 20 can cover the first target device, thereby achieving reasonable resource allocation.

[0217] In some embodiments, please continue reading Figure 24 Step S903 further includes: determining whether the quality of the second signal is less than or equal to a sixth preset threshold, wherein the sixth preset threshold is less than a fifth preset threshold. The step of determining whether the quality of the second signal is less than or equal to the sixth preset threshold can be performed after the step of determining whether the quality of the second signal is greater than or equal to the fifth preset threshold, or it can be performed simultaneously with the step of determining whether the quality of the second signal is greater than or equal to the fifth preset threshold; no specific limitation is made here. Based on this, please continue reading... Figure 24 Following step S903, the control method further includes: when the second signal quality is less than or equal to a sixth preset threshold, re-entering step S100. This way, when the signal quality deteriorates, an optimal antenna can be re-identified for coverage.

[0218] In some embodiments, please continue reading Figure 24 After step S903, the method further includes: when the quality of the second signal is less than the fifth preset threshold and the quality of the second signal is greater than the sixth preset threshold, step S1000 continues to operate.

[0219] In some embodiments, please continue reading Figure 23 or Figure 24 When the first signal quality Q1 is less than the third preset threshold and the second signal quality Q2 is less than the fourth preset threshold, before the directional antenna 30 is driven to rotate by the driving device 40 so that the beam pointing of the directional antenna 30 coincides with the pointing of the target beam in the beam lookup table, the control method further includes the following step S400.

[0220] Step S400: Determine the target beam in the beam lookup table. This step S400 follows steps S100 and S200.

[0221] In some embodiments, please refer to Figure 25 , Figure 25 for Figure 23 or Figure 24 The flowchart illustrates a method for determining a target beam in the control method shown. In this embodiment, step S400 includes the following steps S410 and S420.

[0222] Step S410: The directional antenna 30 is driven by the driving device 40 to rotate sequentially to multiple positions so that the beam direction of the directional antenna 30 coincides with the direction of multiple beams in the beam lookup table. When the beam direction of the directional antenna 30 coincides with the direction of multiple beams in the beam lookup table, the signal quality received by the directional antenna 30 from the first target device is detected to obtain multiple signal quality values. The multiple beams in the beam lookup table can be all beams in the beam lookup table or only some beams in the beam lookup table; no specific limitation is made here.

[0223] Step S420: Determine the target beam in the beam lookup table based on multiple signal qualities.

[0224] In this way, the target beam is determined in the beam lookup table using a round-robin search method. This method is simple and easy to implement.

[0225] When the driving device 40 drives the directional antenna 30 to rotate around the first axis L1, multiple beams in the beam lookup table form multiple beam subsets. These multiple beam subsets are arranged circumferentially along the first axis L1, and each beam subset includes at least a first beam a pointing perpendicular to the first axis L1. Based on this, please refer to... Figure 26 , Figure 26 for Figure 25 The flowchart illustrates a method for determining the target beam, specifically step S410. Step S410 includes the following steps S411 and S412.

[0226] Step S411: The directional antenna 30 is driven to rotate around the first axis L1 by the driving device 40, so that the beam direction of the directional antenna 30 coincides with the direction of the first beam a in the multiple beam subsets. When the beam direction of the directional antenna 30 coincides with the direction of the first beam a in the multiple beam subsets, the signal quality received by the directional antenna 30 from the first target device is detected to obtain multiple third signal qualities. Since each beam subset includes the first beam a, the first beam a in the multiple beam subsets refers to multiple first beams a, each belonging to one of the multiple beam subsets.

[0227] Step S412: Determine the target beam subset based on multiple third signal qualities, and the target beam belongs to the target beam subset.

[0228] In some embodiments, step S412 may include: determining an optimal third signal quality based on a plurality of third signal qualities; and determining the subset of beams containing the first beam a corresponding to the optimal third signal quality as the target beam subset based on the optimal third signal quality. It should be noted that the first beam a corresponding to the optimal third signal quality refers to the first beam a that coincides with the beam direction of the directional antenna 30 when the detected third signal quality is the optimal third signal quality.

[0229] In this way, when the directional antenna 30 rotates until the beam direction coincides with the direction of the plurality of first beams a, it can cover the target device in the XY plane, and the wireless router can be applied to the structure of large single-story houses.

[0230] Based on the above embodiments, when the driving device 40 is further used to drive the directional antenna 30 to rotate around the second axis L2, the beam subset includes multiple beams arranged circumferentially along the second axis L2, and the first beam a is one of these multiple beams. Based on this, please refer to... Figure 27 , Figure 27 for Figure 25 The flowchart illustrates another method for step S410 in the method for determining the target beam. Following step S412, step S410 further includes the following step S413.

[0231] Step S413: Drive the directional antenna 30 to rotate around the second axis L2 by the driving device 40 so that the beam pointing of the directional antenna 30 coincides with the pointing of multiple beams in the target beam sub-set. When the beam pointing of the directional antenna 30 coincides with the pointing of multiple beams in the target beam sub-set, detect the signal quality received by the directional antenna 30 from the first target device to obtain multiple fourth signal qualities.

[0232] Based on the above embodiments, please continue to refer to Figure 27 The above step S420 includes the following step S421.

[0233] Step S421: Determine the target beam in the target beam subset based on multiple fourth signal qualities.

[0234] In some embodiments, step S421 may include: determining an optimal fourth signal quality based on a plurality of fourth signal qualities; and determining the beam corresponding to the optimal fourth signal quality as the target beam based on the optimal fourth signal quality. It should be noted that the beam corresponding to the optimal fourth signal quality refers to the beam in the target beam subset that coincides with the beam direction of the directional antenna 30 when the detected fourth signal quality is the optimal fourth signal quality.

[0235] In this way, multiple beams in the beam lookup table are distributed within the XYZ three-dimensional space. When the directional antenna 30 is rotated until the beam direction coincides with the direction of multiple beams within the XYZ three-dimensional space, the target device within the XYZ three-dimensional space can be covered. The wireless router can be applied to house structures such as villas and duplexes.

[0236] Please see Figure 28 , Figure 28 for Figure 23 or Figure 24 The flowchart illustrates another method for determining the target beam in the control method shown. In this embodiment, step S400 includes the following steps S430 and S440.

[0237] Step S430: Obtain the location information of the first target device;

[0238] Step S440: Determine the target beam in the beam lookup table based on the location information of the first target device.

[0239] In this way, the wireless router does not need to poll to find the target beam, but can quickly determine the target beam, resulting in a faster response and shorter latency.

[0240] In some embodiments, step S440 may include: determining, based on the location information of the first target device, in a beam lookup table, the beam with the smallest angle between its direction and the location of the first target device relative to the wireless router as the target beam. This results in better coverage of the first target device by the directional antenna 30.

[0241] The control methods described in the above embodiments are all implemented based on the purpose of covering the first target device. When there are multiple target devices, the priority of multiple target devices can be determined according to the network type, device type and device usage information (including but not limited to usage time and usage probability) of the target devices. The wireless router covers the target device with the highest priority to improve the rationality of beam switching.

[0242] For details, please refer to Figure 29 , Figure 29 This is a flowchart illustrating a control method for a wireless router provided in some embodiments of this application. Prior to steps S100 and S200, the control method further includes steps S600 and S700.

[0243] Step S600: Determine the priority of multiple target devices based on their device information. The device information includes at least one of network type, device type, wireless data request characteristics, and device usage information, including at least one of usage time and usage probability. For example, Internet of Things (IoT) devices have small data volumes and can be prioritized lower. Conversely, student online learning devices require priority network connectivity during certain time periods and can be prioritized higher during those periods. Based on statistical patterns of the devices, the wireless router, after a period of self-learning, identifies the following scenarios: which are IoT devices, which are low-latency, high-data-volume devices (such as high-definition smart screens, online learning devices, and gaming devices), which are edge devices, and which are fixed-location devices. Based on the time and probability of device appearance, user habits are understood to implement a multi-user priority ranking strategy.

[0244] Step S700: Determine the target device with the highest priority among multiple target devices as the first target device.

[0245] In some embodiments, prior to step S600, the control method further includes: identifying target devices by circling the directional antenna 20 and / or the omnidirectional antenna 30 to obtain multiple target devices.
