All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
It should be noted that the terms "comprises" and "comprising," along with any variations thereof, in the embodiments of the present application are intended to cover non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed or inherent to such process, method, article, or apparatus, but may include other steps or elements not expressly listed.
The embodiment of the application discloses a wireless antenna adjusting method and device, terminal equipment and a storage medium, which can improve the overall antenna performance of a wireless antenna, thereby improving the OTA performance of the terminal equipment.
The following detailed description will be given with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a schematic application scenario of a wireless antenna adjustment method according to an embodiment of the present disclosure, which includes a terminal device 10 and a wireless Access Point (AP) 20. The wireless access point 20 is an access point of a wireless network, and may transmit and receive wireless network signals (such as wireless fidelity Wi-Fi signals), and the terminal device 10 may access the network by communicating with the wireless access point 20 to access the internet or other locations in a local area network. The terminal device 10 may include a Wi-Fi antenna 11, and transmit and receive Wi-Fi signals through the Wi-Fi antenna 11, so as to implement wireless communication between the terminal device 10 and the wireless access point 20.
By way of example, the terminal device 10 may include various devices or systems having Wi-Fi communication functions, such as a mobile phone, a smart wearable device, a vehicle-mounted terminal, a tablet computer, a PC (Personal Computer ), and the like. It should be noted that, the terminal device 10 shown in fig. 1 is a mobile phone, which is merely an example, and does not constitute limitation of the terminal type of the terminal device 10 in the embodiment of the present application. Illustratively, the wireless access point 20 may include various types of wireless access devices or systems, such as wireless routers (including both access and routing functions), wireless base stations, and the like.
In this embodiment of the present application, the terminal device 10 may turn on a Wi-Fi communication function, and receive, through its Wi-Fi antenna 11 (specifically, a receiving antenna RX of the Wi-Fi antenna 11), a first Wi-Fi signal sent by the wireless access point 20; the terminal device 10 may obtain channel setting information corresponding to the wireless access point 20 according to the received first Wi-Fi signal, where the channel setting information is used to indicate a channel adopted by the wireless access point 20 when sending the first Wi-Fi signal; the terminal device 10 may further acquire channel data corresponding to the channel setting information, and adjust the resonant frequency of the Wi-Fi antenna 11 based on the channel data so that the resonant frequency of the Wi-Fi antenna 11 matches the channel data. The terminal device 10 controls the Wi-Fi antenna 11 to adjust the resonant frequency, so that the resonant frequency of the Wi-Fi antenna 11 can be matched with a channel selected when the wireless access point 20 sends the first Wi-Fi signal, and thus the resonant frequency of the Wi-Fi antenna 11 is matched with the center frequency and the bandwidth of the first Wi-Fi signal, wherein when matching is achieved, the resonant frequency of the Wi-Fi antenna 11 is within a frequency range defined by the center frequency and the bandwidth of the first Wi-Fi signal, and thus the Wi-Fi antenna 11 can receive the first Wi-Fi signal with optimal antenna performance. On this basis, no matter how Wi-Fi signals transmitted by the wireless access point 20 change (for example, different channels are selected to transmit Wi-Fi signals), the terminal device 10 can control the Wi-Fi antenna 11 to adjust the resonant frequency along with the first Wi-Fi signals, and keep the resonant point not deviating from the first Wi-Fi signals, so that the antenna performance of the Wi-Fi antenna 11 on each frequency band can be effectively improved, namely, the overall antenna performance of the wireless antenna is improved, and further, the OTA performance of the terminal device 10 in OTA test is improved. Wherein OTA performance can be used to characterize the overall radiation performance of the terminal device 10.
Illustratively, to implement the adjustment of the resonant frequency of the Wi-Fi antenna 11 by the terminal device 10, as shown in fig. 2, the radio frequency link in the terminal device 10 may include the Wi-Fi antenna 11, the tuning circuit 12 and the Wi-Fi transceiver 13, where the Wi-Fi antenna 11 may be connected to the tuning circuit 12, and the tuning circuit 12 may be further connected to the Wi-Fi transceiver 13. The Wi-Fi antenna 11 may include a transmitting antenna TX and a receiving antenna RX (not shown). The tuning circuit 12 is a tunable circuit, and by adjusting the tuning circuit 12, the resonance frequency of the tuning circuit 12 can be changed, thereby adjusting the resonance frequency of the Wi-Fi antenna 11. Alternatively, the Wi-Fi transceiver 13 may have a built-in processor, or may be connected to the processor 14 of the terminal device 10, so as to send a control signal for changing the resonant frequency of the control signal to the tuning circuit 12 under the control of the processor 14, and receive an electrical signal corresponding to the Wi-Fi signal received by the Wi-Fi antenna 11 and transmitted by the tuning circuit 12, and transmit the electrical signal to the processor 14.
Specifically, when the terminal device 10 receives the first Wi-Fi signal sent by the wireless access point 20 through the Wi-Fi antenna 11 thereof, an electrical signal corresponding to the first Wi-Fi signal may be transmitted through the radio frequency link, and channel data (for example, channel center frequency, bandwidth, etc.) corresponding to the wireless access point 20 may be obtained therefrom. When the resonant frequency of the Wi-Fi antenna 11 needs to be adjusted, the processor 14 may control the Wi-Fi transceiver 13 to send a control signal to the tuning circuit 12, where the control signal is used to control the tuning circuit 12 to adjust its resonant frequency (e.g., adjust the impedance of the tuning circuit 12, switch the tuning circuit 12 with a different dielectric material, etc.), so that the resonant frequency of the tuning circuit 12 may be adjusted to match the channel data, so that the resonant frequency of the Wi-Fi antenna 11 may match the channel data. By implementing the method, the overall antenna performance of the Wi-Fi antenna 11 can be improved, and further the OTA performance of the terminal equipment 10 is improved.
Referring to fig. 3, fig. 3 is a flow chart of a wireless antenna adjustment method according to an embodiment of the present disclosure. As shown in fig. 3, the wireless antenna adjustment method may include the steps of:
302. and receiving a first Wi-Fi signal sent by the wireless access point through the wireless fidelity Wi-Fi antenna.
In the embodiment of the application, the terminal equipment has a Wi-Fi communication function, namely, the Wi-Fi antenna is arranged on the terminal equipment, and the Wi-Fi antenna can be used for receiving and transmitting Wi-Fi signals, so that the first Wi-Fi signals sent by the wireless access point are received. In one embodiment, when the terminal device accesses the wireless access point, a wireless communication connection can be established with the wireless access point, and then a first Wi-Fi signal sent by the wireless access point is received. In another embodiment, the terminal device may not access the wireless access point first, but only receive (or scan) the broadcast signal sent by the wireless access point. When the broadcast signal is received, the terminal device can take the broadcast signal as a first Wi-Fi signal, and acquire channel setting information corresponding to the wireless access point according to the broadcast signal by executing the following steps, so as to acquire corresponding channel data, thereby adjusting the resonant frequency of the Wi-Fi antenna, accessing the wireless access point after the adjustment is completed, improving the performance of the receiving antenna of the Wi-Fi antenna, and avoiding the situation that the terminal device is blocked when the terminal device is just accessed into a wireless network.
304. And acquiring channel setting information corresponding to the wireless access point according to the first Wi-Fi signal.
Specifically, when receiving the first Wi-Fi signal through the Wi-Fi antenna, the terminal device actually receives a Wi-Fi data packet sent by the wireless access point. On this basis, the terminal device may unpack and parse the Wi-Fi data packet, and obtain channel setting information corresponding to the wireless access point from the data packet, where the channel setting information is used to indicate a channel (such as a channel identifier, a channel type, etc.) adopted by the wireless access point when sending the first Wi-Fi signal.
The channels may illustratively include a range of frequencies and may be distinguished by a channel center frequency and bandwidth corresponding to each channel. For example, if the channel 1 has a channel center frequency of (a+b)/2 and a bandwidth of b-a, the channel 1 includes a frequency range of [ a, b ]; if the channel 2 has a channel center frequency of (c+d)/2 and a bandwidth of d-c, the channel 2 includes a frequency range of c, d. When the wireless access point transmits the first Wi-Fi signal, a certain channel can be selected, the signal to be transmitted is modulated according to the frequency range included in the channel, and finally the first Wi-Fi signal conforming to the frequency range is output.
In this embodiment of the present application, when the wireless access point sends the first Wi-Fi signal, the data to be sent may be packaged according to the information such as the channel on which the wireless access point performs wireless communication with the terminal device, so as to obtain and send a Wi-Fi data packet that conforms to the Wi-Fi communication format (such as the format specified by the IEEE 802.11 standard). After receiving the Wi-Fi data packet, the terminal equipment can obtain corresponding channel setting information by obtaining the data packet header of the Wi-Fi data packet, so that a channel adopted by the wireless access point when transmitting the first Wi-Fi signal is accurately obtained. In some embodiments, the Wi-Fi packet may include a management frame and a data frame, where the management frame is used for management functions such as device detection, device access, and the like, and the data frame is mainly used for data transmission between the two after the terminal device accesses the wireless access point. After receiving the management frame, the terminal device analyzes the management frame to obtain channel setting information corresponding to the wireless access point.
306. Channel data corresponding to the channel setting information is acquired.
For example, the channel setting information may correspond to channel data one-to-one, where the channel data may include channel data of a channel used by the wireless access point when transmitting the first Wi-Fi signal, such as a channel center frequency, a bandwidth, and the like. The correspondence between the channel setting information and the channel data may be determined according to an existing Wi-Fi communication standard (such as an IEEE 802.11 standard, including an IEEE 802.11a standard, an IEEE 802.11b standard, etc.), or may be determined according to a protocol self-formulated by the wireless access point. It will be appreciated that the terminal device needs to support the standard or protocol to be able to access the wireless access point.
In one embodiment, the terminal device may search the stored channel data table for channel data corresponding to the channel setting information, where the channel data table may record a mapping relationship between the channel setting information and the channel data, for example, channel data corresponding to each different channel identifier, channel data corresponding to each different channel type, and so on.
In another embodiment, the terminal device may further send the channel setting information to a service device connected to the terminal device, and receive channel data corresponding to the channel setting information returned by the service device.
308. And adjusting the resonant frequency of the Wi-Fi antenna based on the channel data so as to enable the resonant frequency of the Wi-Fi antenna to be matched with the channel data.
Illustratively, the terminal device may adjust the resonant frequency of the Wi-Fi antenna by adjusting the tuning circuit of the Wi-Fi antenna, for example, adjusting the impedance of the tuning circuit, switching the tuning circuit with different dielectric materials, and so on, so as to change the resonant frequency of the resonant circuit of the Wi-Fi antenna, and thus change the resonant frequency of the Wi-Fi antenna. By implementing the method, the resonant frequency of the Wi-Fi antenna is adjusted to be matched with the channel data, so that the resonant frequency is matched with a channel selected when the wireless access point sends the first Wi-Fi signal, and the resonant frequency is matched with the center frequency and the bandwidth of the first Wi-Fi signal as much as possible, and the Wi-Fi antenna can receive the first Wi-Fi signal with optimal antenna performance, namely, the antenna gain and the antenna efficiency when the Wi-Fi antenna receives the first Wi-Fi signal are improved.
Therefore, by implementing the wireless antenna adjustment method described in the above embodiment, the Wi-Fi antenna can receive the Wi-Fi signal sent by the wireless access point with the optimal antenna performance by controlling the Wi-Fi antenna to adjust the resonant frequency. On the basis, no matter how Wi-Fi signals sent by the wireless access point change, the terminal equipment can control the Wi-Fi antenna to keep the resonance point of the Wi-Fi antenna not deviating from the Wi-Fi signals, so that the overall antenna performance of the wireless antenna can be effectively improved, and further, the OTA performance of the terminal equipment in OTA test is improved.
Referring to fig. 4, fig. 4 is a flow chart of another wireless antenna adjustment method according to an embodiment of the present disclosure. As shown in fig. 4, the wireless antenna adjustment method may include the steps of:
402. and receiving a first Wi-Fi signal sent by the wireless access point through the wireless fidelity Wi-Fi antenna.
Step 402 is similar to step 302, and will not be described herein.
404. And acquiring channel setting information corresponding to the wireless access point according to the first Wi-Fi signal, wherein the channel setting information at least comprises a channel identifier corresponding to the wireless access point when the wireless access point sends the first Wi-Fi signal.
In this embodiment of the present application, the channel setting information may at least include a channel identifier corresponding to a channel used by the wireless access point when sending the first Wi-Fi signal, where the channel identifier may include a channel number (such as channel 1, channel 2, etc.), a channel identifier (such as channel a, channel b, etc.), and so on. Illustratively, a plurality of channels (i.e., a plurality of frequency ranges) for wireless communication are specified in the IEEE 802.11 standard, including at least 14 channels for the 2.4G band, and at least 60 channels for the 5G band, each having its corresponding channel identification from which the channel employed by the wireless access point when transmitting the first Wi-Fi signal can be accurately determined.
406. A stored channel data table is obtained.
In this embodiment of the present application, the terminal device may locally store a channel data table, where the channel data table may record a mapping relationship between the channel identifier and corresponding channel data, so that the terminal device may directly look up a table according to the obtained channel identifier to obtain channel data corresponding to the channel identifier.
For example, referring to table 1, table 1 shows a mapping relationship between channel identifications of partial channels of the 2.4G band and corresponding channel data, wherein the channel data shown in the table may include channel frequencies (i.e., channel center frequencies) and bandwidths of the channels. It should be noted that, not all channels available in the 2.4G band shown in table 1 are not the only mapping relationship between a channel identifier and corresponding channel data. It will be appreciated that the terminal device may store the data in table 1 in a variety of ways, including tables, documents, etc., and may also store the mapping relationship between the channel identifications of the 5G bands and the corresponding channel data in a similar manner.
Table 1:
| channel identification | Channel frequency (Hz) | Bandwidth (Hz) | Channel identification | Channel frequency (Hz) | Bandwidth (Hz) |
| 1 | 2412 | 20M | 8 | 2447 | 20M |
| 2 | 2417 | 20M | 9 | 2452 | 20M |
| 3 | 2422 | |
10 | 2457 | 20M |
| 4 | 2427 | |
11 | 2462 | 20M |
| 5 | 2432 | |
12 | 2467 | 20M |
| 6 | 2437 | |
13 | 2472 | 20M |
| 7 | 2442 | |
14 | 2422 | 40M |
408. And searching channel data corresponding to the channel identifier in the stored channel data table, wherein the channel data at least comprises channel center frequency and bandwidth.
The terminal device may acquire the channel data table stored by the terminal device after acquiring the channel identifier corresponding to the wireless access point according to the first Wi-Fi signal, and further search the channel data corresponding to the channel identifier on the channel data table, so as to acquire the channel center frequency and the bandwidth adopted by the wireless access point when transmitting the first Wi-Fi signal, and adjust the resonant frequency of the Wi-Fi antenna of the terminal device according to the channel center frequency and the bandwidth in the next step.
As an alternative implementation manner, since the frequency ranges available for wireless communication may be different in different countries or regions, legal channel identifiers may also be different, and the terminal device may further limit the table searching range when searching the channel data table according to the country code in the channel setting information, thereby reducing the table searching time and improving the table searching efficiency.
The terminal device may also determine, for example, a frequency range corresponding to the country code according to the country code included in the channel setting information after acquiring the stored channel data table, and then search the channel data corresponding to the above-mentioned channel identifier and belonging to the frequency range in the channel data table. For example, for the 2.4G band, when the country code included in the channel setting information is "CN", the terminal device may look up the channel data table only in the range of the channel identifications of 1 to 13; when the country code included in the channel setting information is "US", the terminal device may look up the channel data table only in the range of the channel identifications of 1 to 11.
By implementing the method, the searching range of the channel data table can be further limited according to the country code included in the channel setting information, so that the speed of searching the table by using the channel identification is increased, and the efficiency of adjusting the wireless antenna is further improved.
410. And adjusting the resonant frequency of the Wi-Fi antenna based on the channel data so as to enable the resonant frequency of the Wi-Fi antenna to be matched with the channel data.
Step 410 is similar to step 308, and will not be described here.
Therefore, by implementing the wireless antenna adjustment method described in the above embodiment, channel data of a channel adopted by a wireless access point when transmitting Wi-Fi signals can be rapidly and accurately determined by a table look-up mode, and further, the Wi-Fi antenna of the terminal device can be controlled to adjust resonant frequency according to the channel data, so that the Wi-Fi antenna receives Wi-Fi signals transmitted by the wireless access point with optimal antenna performance, the overall antenna performance of the wireless antenna is improved, and further, the OTA performance of the terminal device is improved; in addition, the country code in the channel setting information is acquired to limit the table look-up range when the channel data table is searched, so that the table look-up time is reduced, the table look-up speed is improved, and the efficiency of wireless antenna adjustment is improved.
Referring to fig. 5, fig. 5 is a flowchart of another wireless antenna adjustment method according to an embodiment of the present disclosure. As shown in fig. 5, the wireless antenna adjustment method may include the steps of:
502. and receiving a first Wi-Fi signal sent by the wireless access point through the wireless fidelity Wi-Fi antenna.
Step 502 is similar to step 302, and will not be described herein.
504. And acquiring channel setting information corresponding to the wireless access point according to the first Wi-Fi signal, wherein the channel setting information at least comprises a channel identifier corresponding to the wireless access point when the wireless access point sends the first Wi-Fi signal.
506. A stored channel data table is obtained.
508. And searching channel data corresponding to the channel identifier in the stored channel data table, wherein the channel data at least comprises channel center frequency and bandwidth.
510. From among a plurality of tuning circuits of the Wi-Fi antenna, a target tuning circuit that matches the channel data is determined.
In the embodiment of the application, the Wi-Fi antenna of the terminal equipment can be connected with a plurality of tuning circuits, and the Wi-Fi antenna is ensured to be conducted with the determined target tuning circuit only at the same time through the switch. The number of tuning circuits may be equal to the number of channels in the channel data table. In one embodiment, a switch may be disposed between the Wi-Fi antenna and each tuning circuit, and when a target tuning circuit is determined, the switch corresponding to the target tuning circuit may be turned on, while the switches of other tuning circuits are turned off. In another embodiment, a Wi-Fi antenna and multiple tuning circuits may be connected in a single pole, multiple throw fashion, thereby ensuring that only a determined target tuning circuit can be conductively connected to the Wi-Fi antenna at the same time. Illustratively, as shown in fig. 6, fig. 6 is a modular schematic diagram of a plurality of tuning circuits as disclosed in embodiments of the present application. It should be noted that the multiple tuning circuits shown in fig. 6 are connected to the Wi-Fi antenna through a single pole multiple throw switch, which is only an example. In some embodiments, the selection and switching of multiple tuning circuits may also be implemented by an FPGA (Field Programmable Gate Array ), PLD (Programmable Logic Devices, large-scale programmable logic device), or the like.
Specifically, the above-mentioned multiple tuning circuits may be equivalent to multiple sub-circuits of the tunable circuit module of the terminal device, and each tuning circuit may be provided with a different dielectric material, which has a different dielectric constant, so that each tuning circuit may be tuned with the Wi-Fi antenna at a different frequency, i.e. each tuning circuit corresponds to different tuning data, respectively. When the terminal device finds the channel data corresponding to the channel identifier, a matched target tuning circuit can be determined from the tuning circuits according to the channel data, and the tuning data of the target tuning circuit is matched with the channel data obtained by searching (for example, the tuning data is equal to the channel data, and the difference value between the tuning data and the channel data is smaller than a threshold value, etc.).
Optionally, when there is no tuning circuit matching with the channel data in the plurality of tuning circuits, a tuning circuit whose tuning frequency (i.e., the tuning data) is closest to the frequency of the first Wi-Fi signal may be determined as the target tuning circuit, so that the overall antenna performance of the Wi-Fi antenna is improved as much as possible by adjusting the resonant frequency of the Wi-Fi antenna.
512. And controlling the Wi-Fi antenna to be switched to the target tuning circuit so as to adjust the resonant frequency of the Wi-Fi antenna to be the resonant frequency of the target tuning circuit, wherein the resonant frequency of the target tuning circuit is matched with the frequency of the first Wi-Fi signal.
Specifically, the terminal device may control the Wi-Fi antenna to switch to the determined target tuning circuit, so that the resonant frequency of the Wi-Fi antenna is adjusted to the resonant frequency of the target tuning circuit, where the resonant frequency is matched with the channel data, that is, the resonant frequency may be matched with the frequency of the first Wi-Fi signal sent by the wireless access point (that is, in a frequency range corresponding to a channel used by the wireless access point to send the first Wi-Fi signal), so that the antenna gain and the antenna efficiency when the Wi-Fi antenna receives the first Wi-Fi signal are improved, and the Wi-Fi antenna can receive the first Wi-Fi signal with optimal antenna performance. When the wireless access point selects different channels to send the first Wi-Fi signal, the terminal equipment can control the Wi-Fi antenna to be switched to another tuning circuit, so that the resonance frequency of the Wi-Fi antenna is kept to be matched with the frequency of the first Wi-Fi signal, and the overall antenna performance of the Wi-Fi antenna is improved.
As an alternative embodiment, the channel data may belong to different channel packets, each channel packet may include channel data corresponding to at least one adjacent channel, and the number of the tuning circuits may be equal to the number of channel packets. For example, referring to table 2, table 2 shows one example of grouping partial channels of the 2.4G band.
Table 2:
for example, after the terminal device finds the channel data corresponding to the channel identifier, it may determine a channel packet corresponding to the channel data, and then determine, from the plurality of tuning circuits, a target tuning circuit that matches the channel packet. Because the channel data of adjacent channels have smaller phase difference, namely the channel data corresponding to the channels included in the same channel group have smaller phase difference, by arranging the tuning circuits corresponding to the channel groups, a plurality of adjacent channels can be considered through the same tuning circuit, so that the number of the tuning circuits required to be arranged can be reduced, the circuit design is simplified, and the efficiency of determining the target tuning circuit is improved; and the method can match channel data in a larger range as much as possible with fewer tuning circuits, reduce the occurrence of the condition that no tuning circuit matched with the channel data exists, and ensure the reliability of wireless antenna adjustment.
Therefore, by implementing the wireless antenna adjustment method described in the above embodiment, the adjustment of the resonant frequency of the Wi-Fi antenna can be achieved by setting a plurality of switchable tuning circuits, so that the Wi-Fi antenna receives Wi-Fi signals sent by the wireless access point with optimal antenna performance, the overall antenna performance of the wireless antenna is improved, and further the OTA performance of the terminal device is improved; in addition, by setting the channel group including at least one adjacent channel to determine the target tuning circuit to be switched, the number of tuning circuits to be set can be reduced, the efficiency of determining the target tuning circuit can be improved, and meanwhile, fewer tuning circuits can be matched with the channel data in a larger range as much as possible, so that the reliability of adjustment of the wireless antenna can be ensured.
Referring to fig. 7, fig. 7 is a flowchart of another wireless antenna adjustment method according to an embodiment of the present disclosure. As shown in fig. 7, the wireless antenna adjustment method may include the steps of:
702. and receiving a first Wi-Fi signal sent by the wireless access point through the wireless fidelity Wi-Fi antenna.
Step 702 is similar to step 302 described above, and will not be described here again.
704. And acquiring channel setting information corresponding to the wireless access point according to the first Wi-Fi signal, wherein the channel setting information at least comprises a channel identifier corresponding to the wireless access point when the wireless access point sends the first Wi-Fi signal.
706. A stored channel data table is obtained.
708. And searching channel data corresponding to the channel identifier in the stored channel data table, wherein the channel data at least comprises channel center frequency and bandwidth.
710. A channel packet corresponding to the channel data is determined.
712. From among the plurality of tuning circuits of the Wi-Fi antenna, a target tuning circuit that matches the channel minutes is determined.
714. And controlling the Wi-Fi antenna to be switched to the target tuning circuit so as to adjust the resonant frequency of the Wi-Fi antenna to be the resonant frequency of the target tuning circuit, wherein the resonant frequency of the target tuning circuit is matched with the frequency of the first Wi-Fi signal.
716. And receiving a second Wi-Fi signal sent by the wireless access point.
In the embodiment of the application, after the terminal device controls the Wi-Fi antenna to adjust the resonant frequency, the terminal device may re-receive the second Wi-Fi signal sent by the wireless access point. For example, the terminal device may re-access the wireless access point and establish a wireless communication connection, and then receive a second Wi-Fi signal sent by the wireless access point. According to the received second Wi-Fi signal, the terminal device may repeat the steps 702 to 708, and acquire channel data of a channel adopted by the wireless access point when the second Wi-Fi signal is transmitted. When the re-acquired channel data matches the current resonant frequency of the Wi-Fi antenna, it indicates that the adjustment of the Wi-Fi antenna is completed, otherwise, the steps 710 to 714 may be continued to be performed to perform the adjustment again.
718. And detecting the antenna performance of the Wi-Fi antenna according to the second Wi-Fi signal.
The antenna performance may include parameters such as antenna gain, antenna efficiency, etc., for example. After detecting the antenna performance of the Wi-Fi antenna according to the second Wi-Fi signal, the terminal device can determine whether the antenna performance meets the expected performance requirement in the next step, so that the effectiveness of wireless antenna adjustment can be ensured.
720. And when the antenna performance is lower than the performance threshold, sending a channel switching request to the wireless access point, wherein the channel switching request is used for requesting the wireless access point to switch a channel for sending a second Wi-Fi signal.
For example, when the terminal device detects that the Wi-Fi antenna performance is lower than the performance threshold according to the received second Wi-Fi signal, it may be considered that the resonant frequency of the Wi-Fi antenna cannot be matched with the channel data of the channel used by the wireless access point to transmit the second Wi-Fi signal after the Wi-Fi antenna is adjusted (for example, the wireless access point switches the channel used to transmit the second Wi-Fi signal, the resonant circuit on the terminal device cannot be adjusted to the required resonant frequency, etc.). On this basis, by sending a channel switching request to the wireless access point, the wireless access point can be requested to switch the channel for sending the second Wi-Fi signal, so that the terminal device can re-execute the steps 702 to 714 according to the second Wi-Fi signal after switching the channel, so as to adjust the resonant frequency of the Wi-Fi antenna again, so that the resonant frequency of the Wi-Fi antenna is matched with the channel data of the switched channel, thereby improving the overall antenna performance of the wireless antenna, and ensuring the effectiveness and reliability of adjustment of the wireless antenna.
Therefore, by implementing the wireless antenna adjustment method described in the above embodiment, the Wi-Fi antenna can receive the Wi-Fi signal sent by the wireless access point with the optimal antenna performance by controlling the Wi-Fi antenna to adjust the resonant frequency; in addition, when the resonant frequency of the Wi-Fi antenna cannot be adjusted to the required resonant frequency, the wireless access point is requested to switch the channel adopted by the Wi-Fi antenna to transmit the Wi-Fi signal, and the adjustment is carried out again, so that the effectiveness and the reliability of the adjustment of the wireless antenna can be ensured.
