There are a variety of existing AP antenna control schemes. Such as camera recognition and automatic control of antenna radiation angle systems, application of this solution to the consumer field would violate customer privacy.

For another example, a WiFi (wireless network communication technology) positioning and automatic control antenna radiation angle system, the scheme also needs at least 3 APs, which has a certain requirement on signal density, and a positioning message of WiFi affects normal communication of the APs, so that throughput is reduced.

The directional antenna is an antenna which is particularly strong in transmitting and receiving electromagnetic waves in a certain or a plurality of specific directions, and is zero or very small in transmitting and receiving electromagnetic waves in other places, and the directional transmitting antenna can be used for effectively utilizing radiation power, improving the covering capacity of products, enhancing the signal strength and improving the anti-interference capacity.
In some embodiments, the access point AP antenna parameter determination method is performed by a processor of the AP;
specifically, the AP is started, azimuth and pitching angles are initialized, the antenna enters a default position, the initialized azimuth and pitching angles can be selected as AP right-over angles, and the antenna is initialized to turn to the default position through a motor.
In some embodiments, the ID design of the AP appearance is generally asymmetric, i.e., has a front-back division, the azimuth angle variation range perpendicular to the front may be defined as 0 °, the azimuth angle variation range of the horizontal plane is [ -180 °, +180° ], the elevation angle may be defined as the elevation angle is [ -90 °, +90° ], and the angle may satisfy the 3D full 360 ° direction orientation centered on the AP; default may be initially [0 °,0 ° ], i.e. the front side of the AP product.
The processor of the AP may start an FMCW (Frequency Modulated Continuous Wave ) function, where the basic principle of the FMCW function is that the transmitted wave is a high-frequency continuous wave, the transmitted frequency of the high-frequency continuous wave changes with time according to a triangle wave rule, and the echo frequency received by the FMCW function is the same as the change rule of the transmitted frequency, and includes a time difference, and the position and/or direction of the UE corresponding to the base station is calculated according to the time difference. Because of the relative movement of the measured object and the AP, the emitted and reflected electromagnetic wave has a frequency difference of a rising/falling edge device, and the relation between the frequency difference and the distance and speed of the measured object can be counted and found according to actual experiments, so that the distance measurement and the speed measurement can be carried out on one or even a plurality of targets at a short distance.
The status parameters of at least one UE are determined by activating the FMCM function, wherein the UE is a user terminal, the number of which may be 1,2,3 or more.
The state parameter of the UE is an antenna parameter of the UE.
In some embodiments of the present application, in some embodiments,
the antenna parameters of the UE further include at least:
azimuth angle;
a pitch angle;
antenna lobe width;
maximum gain of the antenna;
channel quality index;
the azimuth angle refers to an included angle of the antenna in the horizontal plane direction and the north direction;
pitch angle refers to the downward or upward pointing angle of the antenna relative to the horizontal;
lobe width is the angle at which a sector formed by radio wave radiation opens;
the maximum gain of an antenna refers to the ratio of the total input power of the antenna in no direction to the total input power of the directional antenna, and is used for measuring the capability of the antenna to send and receive signals in a specific direction;
the channel quality index refers to a channel quality index in the interactive frame, for example, an MCS (Modulation and Coding Scheme, modulation coding scheme) index in the user terminal communication.
Determining a first antenna parameter of an AP according to the antenna parameter of the UE, wherein the first antenna parameter of the AP at least comprises an azimuth angle and/or a pitch angle of an antenna of the AP;
specifically, according to the antenna parameters of the UE, a relationship with the index in the terminal communication frame is found through a large number of experiments, and a mapping relationship between the parameters and the index is established and stored in the AP in a table manner to perform quick judgment, so that the first antenna parameters of the AP are determined, and real-time computing resources are reduced.
And receiving a second antenna parameter of the AP antenna acquired by a sensor.
In some embodiments, the position sensor collects real-time data of the antenna during the rotation angle, and determines a second antenna parameter of the AP antenna. The actual antenna parameters of the antenna of the AP during the adjustment process are thus detected by the position sensor to determine that the antenna of the AP is adjusted to the desired antenna parameters.
In some embodiments, the method further comprises:
if the second antenna parameter is different from the first antenna parameter, continuing to output a control instruction to enable the antenna to rotate by an angle.
If the current position sensor detects that the actual second antenna parameter is the same as the first antenna parameter, the AP completes the adjustment of the antenna parameter, so that the adjustment of the antenna parameter of the AP can be temporarily stopped. If the second antenna parameter is different from the first antenna parameter, continuing to output an instruction to control the antenna parameter of the AP to continue to be adjusted until the actual second antenna parameter of the AP is at the same position as the first antenna parameter.
In yet other embodiments, the method further comprises:
and if the second antenna parameter is the same as the first antenna parameter, determining that the redetermining condition of the first antenna parameter is met.
If the wireless environment changes and/or the user has moved significantly relative to the AP, it may be necessary to readjust the antenna parameters of the AP to ensure communication quality.
Therefore, in the embodiment of the present disclosure, after the adjustment of the antenna parameter of the AP is completed this time, that is, after the actual second antenna parameter of the AP is the same as the first antenna parameter, it is determined whether the redetermining condition of the first antenna parameter is satisfied periodically or aperiodically.
If the redetermining condition is met, the redetermining of the first antenna parameter is required to go to the next round of adjustment of the antenna parameters of the AP, by which adjustment the antenna parameters of the AP are brought into a state where better communication quality can be provided for a longer time.
For example, the processing module of the AP periodically determines whether the first antenna parameter re-determination condition is met. For another example, when the processing module of the AP discovers that the state parameters such as the antenna parameters of the UE have changed by more than a preset value according to the state parameters of the UE, the condition for redetermining the first antenna parameters may be considered to be satisfied.
In summary, there are many ways of determining the first antenna parameter redetermination condition, and the specific implementation is not limited to the above example.
In some embodiments, the redetermination condition may be that the change of m reaches a critical point according to the MCS index m in the communication frame of the AP and the terminal, and if the change reaches the critical point, the redetermination condition is satisfied, where the value of m ranges from 0 to 11, and may be a number in 1,2,3 or other ranges, and the larger the value of m, the better the communication quality between the AP and the terminal is indicated.
In other embodiments, the redetermining condition may also be whether the movement track, the current azimuth and elevation angle, the antenna lobe, the channel quality and the movement rate of each user terminal exceed the threshold values, and when one of the movement track, the current azimuth and elevation angle, the antenna lobe, the channel quality and/or the movement rate of the user terminal exceeds the corresponding threshold value, the redetermining condition of the first antenna parameter may be considered to be satisfied.
For example, the optimal direction angle [ phi, theta ] |t1 obtained by the AP at time t1 and the optimal direction angle [ phi, theta ] |t2 calculated by the AP at t2=t1+Δt are set, the threshold value is k=Δphi×1+Δtheta×2, where x1 and x2 are pre-weight coefficients, and represent the importance or sensitivity of azimuth angle and pitch angle obtained through experiments, and the k value is also determined in relation to the lobe, gain, and the like of the communication antenna.
If the redetermining condition of the first antenna parameter is satisfied, returning to the step of determining the state parameter of the at least one UE, specifically:
if the redetermining condition is met, determining that the azimuth angle of the antenna needs to be changed again, and recalculating the track and the position of the user to obtain a new azimuth angle and a new pitch angle.
