These terms are mainly used to distinguish one component from another component. In addition, the term "or" used herein may include any one or more combinations of the associated listed items depending on the actual situation.

[0025] Example

[0026] See also Figure 1 and Figure 2 As shown, Figure 1 is a functional block diagram of a wireless communication device according to an embodiment of the present application. Figure 2 This is a schematic diagram of a first embodiment of a wireless communication device of the present application. The present application provides a wireless communication device D, which includes an antenna 1 , a geomagnetic sensor 2 , a satellite positioning module 3 and a data processing module 4 .

[0027] The wireless communication device D can be connected to a base station BS through antenna 1. In the present application, antenna 1 is a directional antenna, which is an antenna that transmits or receives radio wave power in a specific direction. Since antenna 1, as a directional antenna, can only receive radio waves from a specific direction, its placement, direction and elevation angle will affect the signal reception performance. Geomagnetic sensor 2 is connected to antenna 1. Geomagnetic sensor 2 is mainly used to detect geomagnetic direction. Satellite positioning module 3 is electrically connected to antenna 1, and satellite positioning module 3 can be a positioning device that supports the Global Positioning System (GPS). However, the present application is not limited to this. Satellite positioning module 3 can also support GLONASS, GALILEO, Beidou satellite navigation system or other satellite positioning systems. Satellite positioning module 3 can receive positioning signals from the GPS system and generate a location information of the wireless communication device D based on it. For example, the location information can be longitude and latitude or coordinates of other geographic coordinate systems.

[0028] For example, the data processing module 4 may be various data processing units with signal processing functions, such as but not limited to, a microprocessor or micro-controller, a central processing unit (CPU), which has the capabilities of calculation, storage, output / input, etc., and can accept and process various coding instructions to perform various logical operations and arithmetic operations, and output corresponding calculation results. The data processing module 4 is electrically connected to the antenna 1, the geomagnetic sensor 2 and the satellite positioning module 3. The geomagnetic sensor 2 is used to detect the geomagnetic direction and output a geomagnetic sensing signal, and the data processing module 4 calculates the azimuth angle to which the antenna 1 points based on the geomagnetic sensing signal. In detail, the geomagnetic sensing signal includes the direction information of the earth's magnetic field, and after the data processing module 4 obtains the geomagnetic field direction information, it can calculate the angle between the current antenna and the geomagnetic field direction to confirm the azimuth angle to which the antenna is currently pointing. Figure 2As shown, after the data processing module 4 obtains the azimuth angle of the antenna 1 , the location information of the wireless communication device D, and the location information of the base station BS, the data processing module 4 can calculate an angle θ between the antenna 1 and the base station BS based on the information.

[0029] Continue reading Figure 1 , the wireless communication device D also includes a motion sensor 5. For example, the motion sensor 5 includes an accelerometer and a gyroscope, which are electrically connected to the data processing module 4. The motion sensor 5 is used to sense the movement information of the antenna 1. The accelerometer is a device that can measure the change in acceleration of a target object (that is, can sense the movement of the target object), and the gyroscope can be a device that can sense the change in angular velocity of a target object (that is, can sense the deflection angle of the target object). The movement information includes the change in acceleration of the antenna 1 when it moves, sensed by the accelerometer, and the change in angular velocity of the antenna 1 when it rotates, sensed by the gyroscope. The data processing module 4 calculates a pitch angle of the antenna 1 based on the movement information.

[0030] Continue reading Figure 1 and Figure 2 , the wireless communication device D can transmit the angle θ and the pitch angle to a network management center C where the mobile communication system operator is located. Specifically, the network management center C is connected to the base station BS, and the information transmission between the wireless communication device D and the network management center C is carried out through the antenna 1 and the base station BS. The network management center C calculates a recommended adjustment angle of the antenna 1 based on at least the angle θ and the pitch angle. After obtaining the recommended adjustment angle, the system operator can adjust it at the user's residence, or provide the recommended adjustment angle to the user, and the user adjusts the angle by himself. In detail, the recommended adjustment angle can be used as an important reference for the initial adjustment of the antenna 1. The user can first adjust the antenna 1 of the wireless communication device D to the recommended adjustment angle, and then gradually fine-tune it to optimize the reception performance. Compared with the prior art that requires repeated blind trial and error when adjusting the antenna angle, the wireless communication device D of the present application obtains the recommended adjustment angle through the azimuth angle, pitch angle of the antenna 1, the location information of the wireless communication device D and the base station BS as the initial adjustment angle, avoiding blind trial and error that is time-consuming and labor-intensive, and reducing uncertainty.

[0031] The wireless communication device D also includes a mobile communication module 6, which is electrically connected to the data processing module 4 and the antenna 1. For example, the mobile communication module 6 can support ETSI LTE or 5G NR communication standards, but the present application is not limited thereto. The mobile communication module 6 can collect and transmit channel parameters during signal transmission between the wireless communication device D and the base station BS, and transmit them to the network management center C through the base station BS, so that the network management center C can confirm the signal transmission quality by reading and analyzing the channel parameters. For example, the channel parameters include received signal strength indication (RSSI), reference signal received power (RSRP) and reference signal received quality (RSRQ). Furthermore, the network management center C calculates the recommended adjustment angle based on the angle θ, the pitch angle and the signal transmission quality obtained through the above-mentioned channel parameters.

[0032] See also Figure 3 As shown, Figure 3 This is a functional block diagram of the data processing module of the present application. The data processing module 4 includes a data acquisition unit 41, a data calculation unit 42, a data correction unit 43 and a data integration unit 44. The data acquisition unit 41 is used to collect relevant information sensed by the geomagnetic sensor 2 and the motion sensor 5 (i.e., the geomagnetic direction and the acceleration / angular velocity change). The data calculation unit 42 is used to receive the relevant information and calculate the azimuth and pitch angles. The data correction unit 43 corrects the azimuth and pitch angles according to the use environment of the antenna 1 (for example, the wireless communication device D may be placed on an uneven surface), and then provides the obtained correction values ​​to the data calculation unit 42. The data calculation unit 42 calculates the angle θ between the antenna 1 and the base station BS based on these correction values ​​and the location information of the wireless communication device D and the base station BS. The data integration unit 44 is used to receive at least one of the above-mentioned information (i.e., the location information of the wireless communication device D, the corrected azimuth and elevation angles of the antenna 1, and the angle θ), and output it to the network management center C through the mobile communication module 6, so that the network management center C can calculate the recommended adjustment angle based on the angle θ and the elevation angle, combined with the signal transmission quality obtained by the channel parameters.

[0033] See also Figure 4 As shown, Figure 4 4 is a functional block diagram of the data processing module, geomagnetic sensor and motion sensor of the present application. It is worth mentioning that in the present application, the data processing module 4 is connected via an integrated circuit bus (Inter-Integrated Circuit, I 2C) interface, which includes two signal lines, serial clock (SCL) and serial data (SDA), to read the sensing data of geomagnetic sensor 2 and motion sensor 5. In addition, during the process of adjusting the orientation of antenna 1, data processing module 4 can monitor whether the device status generates abnormal changes at any time by receiving interrupt request (IRQ) from motion sensor 5. Specifically, when motion sensor 5 senses that antenna 1 is moved or rotated, motion sensor 5 will output an interrupt signal INT to notify data processing module 4, so that data processing module 4 can receive interrupt request (IRQ) from motion sensor 5. 2 The C interface reads the data sensed by the geomagnetic sensor 2 and the motion sensor 5 .

[0034] Continue reading Figure 1 and Figure 3 , the wireless communication device D also includes an antenna adjustment module 7, which is electrically connected to the antenna 1 and the data processing module 4. In one embodiment, the antenna adjustment module 7 mainly includes a motor 71, and the data processing module 4 also includes a motor control unit 45. The motor 71 can be any electrical device that can convert electrical energy into mechanical energy and generate kinetic energy to drive other devices. When the network management center C calculates the recommended adjustment angle, it can output corresponding instructions to the data processing module 4 in a remote control manner, so that the motor control unit 45 of the data processing module 4 controls the direction of the motor 71 to rotate the antenna 1 according to the recommended adjustment angle. The method of controlling the motor 71 to rotate the antenna 1 by the motor control unit 45 can save the process and time of the system operator going to the house or the user manually adjusting it, further improving the user experience.

[0035] Furthermore, when the antenna 1 rotates to the corresponding position according to the recommended adjustment angle, the mobile communication module 6 will continue to collect the channel parameters (RSSI, RSRP, RSRQ) during the signal transmission between the wireless communication device D and the base station BS, and transmit them back to the network management center C through the base station BS, so that the network management center C can continuously monitor the quality of signal transmission and continue to fine-tune the position of the antenna 1 through remote control until the antenna 1 rotates to the best reception angle. After the reception optimization is achieved, the data processing module 4 will transmit the final position of the antenna 1 back to the network management center C to complete the antenna position adjustment process.

[0036] See also Figure 5 As shown, Figure 5This is a schematic diagram of the second embodiment of the wireless communication device of the present application. The above-mentioned antenna azimuth adjustment process can be applied to the azimuth adjustment of multiple wireless communication devices D at the same time. When there is a need to increase or decrease the number of base stations in an area or to move them, the system operator can collect the azimuth information of all wireless communication devices D in the area, and then plan the base station location and antenna azimuth according to the device density and network traffic of the wireless communication devices D in the area. For example, Figure 5 As shown, there are originally two base stations BS1 in the area. After a new base station BS2 is added, the system operator adjusts the position of a part of the wireless communication devices D in the area by remote control according to the device density and network traffic in the area, thereby eliminating the need for manual adjustment of individual home services, reducing operating costs, and reducing network congestion and other problems such as poor signal and slow transmission speed in the area.

[0037] Advantageous Effects of Embodiments

[0038] The wireless communication device D provided in the present application can obtain the azimuth angle and elevation angle of the antenna 1 through the signals sensed by the geomagnetic sensor 2 and the motion sensor 5, and obtain the recommended adjustment angle of the antenna 1 of the wireless communication device D in combination with the location information of the wireless communication device D and the location information of the base station BS, so that the user can adjust the azimuth angle of the wireless communication device D in real time and effectively, reducing the time required for installation or adjustment.

[0039] Furthermore, the wireless communication device D provided by the present application may be provided with a motor control unit 45 and an antenna adjustment module 7 (including a motor 71), so that it has a remote control function. When the network management center C calculates the recommended adjustment angle, it can control the operation of the motor control unit 45 of the data processing module 4 by remote control, so that the motor control unit 45 drives the motor 71 to rotate the direction of the antenna 1, thereby eliminating the process and time of the system operator visiting the home or the user manually adjusting the angle, further improving the user experience.

[0040] In addition, the antenna orientation adjustment process provided by the present application can also be applied to the orientation adjustment of multiple wireless communication devices D at the same time. When there is a need to increase or decrease the number of base stations in an area or to move them, the system operator can collect the orientation information of all wireless communication devices D in the area, and then plan the base station location and antenna orientation according to the device density and network traffic of the wireless communication devices D in the area.
