In the embodiment of the application, the WIFI module performs data transmission with fixed transmitting power (a value between 12dBm and 20 dBm) in the conventional terminal. Because the transmission power of the existing terminal WIFI is fixed, no relevant mechanism is provided for adjusting the transmission power, and the power control is automatically carried out.

Referring to fig. 2, fig. 2 is a schematic flowchart of a first exemplary embodiment of a WIFI transmission power adjustment method according to the present application. The WIFI transmission power adjusting method is applied to electronic equipment, and comprises the following steps:
step S10, determining the distance between the electronic equipment and the wireless equipment which is in WIFI connection with the electronic equipment;
the execution main body of the method of this embodiment may be a control device, the control device is disposed on a current device, the current device may be an electronic device such as a mobile phone, a tablet computer, and a notebook computer with a WIFI function, and the execution main body of the method of this embodiment may also be a Central Processing Unit (CPU) of the electronic device directly.
In an embodiment, an Ultra Wide Band (UWB) Chipset (Chipset) module is disposed in the electronic device, and referring to fig. 6, the Ultra Wide Band Chipset module can transmit and receive an Ultra Wide Band signal, and can determine a distance between the electronic device and a receiving end of the Ultra Wide Band signal after the receiving end feeds back a response signal. The step S10 specifically includes: step S11, sending an ultra-wideband ranging signal to the wireless device through the ultra-wideband chip set module, and recording first sending time of the ultra-wideband ranging signal sent by the ultra-wideband chip set module; step S12, receiving a response signal fed back by the wireless device, and recording a first receiving time for receiving the response signal, wherein the response signal comprises a second receiving time for the wireless device to receive the ultra-wideband ranging signal and a second transmitting time for the wireless device to send the response signal; step S13, determining a distance between the electronic device and the wireless device according to the first transmission time, the second transmission time, the first reception time, and the second reception time.
In this embodiment, the electronic device may record the time when the ultra-wideband chipset module transmits the ultra-wideband ranging signal and the time when the ultra-wideband chipset module receives the feedback signal, and the wireless device may record the time when the wireless device receives the ultra-wideband ranging signal and the time when the wireless device transmits the feedback signal, and notify the electronic device through the feedback signal. The preset distance formula is as follows: d ═ c [ T ]J1-TF1-(TF2-TJ2)](ii)/2, wherein d is the distance between the electronic device and the wireless device feeding back the signal; c is the electromagnetic wave propagation speed; t isF1Is a first transmission time; t isF2Is a second transmission time; t isJ1Is a first reception time; t isJ2Is the second reception time.
Further, the channel of the ultra-wideband ranging signal can be selected to be any one of CH 8-15, so as to avoid interference caused by overlapping with the channel of the WIFI signal.
In one embodiment, the electronic device is provided with a bluetooth module, and the bluetooth module can transmit a bluetooth ranging signal and can receive a response signalAnd determining the distance between the electronic equipment and the receiving end. The step S10 specifically includes: step S101, a Bluetooth ranging signal is sent to the wireless equipment through the Bluetooth module, and third sending time of the Bluetooth ranging signal sent by the Bluetooth module is recorded; step S102, receiving a response signal fed back by the wireless device, and recording a third receiving time for receiving the response signal, wherein the response signal comprises a fourth receiving time for the wireless device to receive the Bluetooth ranging signal and a fourth transmitting time for the wireless device to transmit the response signal; step S103, determining the distance between the electronic equipment and the wireless equipment according to the third transmitting time, the fourth transmitting time, the third receiving time and the fourth receiving time. Similarly, the distance between the electronic device and the wireless device feeding back the signal is calculated according to the following preset distance formula, where the preset distance formula is: d ═ c [ T ]J3-TF3-(TF4-TJ4)](ii)/2, wherein d is the distance between the electronic device and the wireless device feeding back the signal; c is the electromagnetic wave propagation speed; t isF3Is a third transmit time; t isF4Is a second transmission time; t isJ3Is the third reception time; t isJ4Is the fourth reception time. In this embodiment, the original bluetooth module of the electronic device can transmit the bluetooth signal for ranging, so as to dynamically adjust the transmission power along with the distance without increasing additional hardware cost.
Step S20, determining a space loss value according to a distance between the electronic device and the wireless device and a preset space loss formula;
in this embodiment, the preset spatial loss formula is as follows: l is 32.44+20lgd +20lgf, where L is a space loss value, d is a distance between the electronic device and the wireless device, f is a WIFI communication frequency between the electronic device and the wireless device, and f can be set by a user as needed, which is not limited in this embodiment.
Step S30, determining the lowest transmission power of the electronic device for communicating with the wireless device according to the spatial loss value, and controlling the electronic device to communicate with the wireless device according to the lowest transmission power.
In this embodiment, the lowest transmission power is the spatial loss value + the signal receiving sensitivity of the wireless device, the receiving sensitivity defines the lowest signal strength that the receiving end can receive and still work normally, and the receiving sensitivity of the wireless transmission is similar to the hearing of people in communication. The signal reception sensitivity is an inherent characteristic of the wireless device, and therefore, the electronic device can directly acquire it. The signal receiving sensitivities of different wireless devices may be different, and correspondingly, even if the distances between the two wireless devices and the electronic device are the same, the minimum transmitting power for the electronic device to communicate with the different wireless devices may be different.
The embodiment is applied to electronic equipment, and the distance between the electronic equipment and wireless equipment in WIFI connection with the electronic equipment is determined; determining a space loss value according to a distance between the electronic equipment and the wireless equipment and a preset space loss formula; and determining the lowest transmission power of the electronic equipment for communicating with the wireless equipment according to the space loss value, and controlling the electronic equipment to communicate with the wireless equipment according to the lowest transmission power.
This embodiment has set up a set of new WIFI transmit power adjustment scheme, has realized that WIFI transmit power is along with the distance dynamic adjustment between wireless device and the electronic equipment, compares in prior art, can reduce the produced extra consumption of fixed transmit power.
Further, when electronic equipment includes ultra wide band chipset module, because ultra wide band communication itself has extremely strong interference killing feature, positioning accuracy can reach 10cm, consequently confirms the distance between wireless device and the electronic equipment through ultra wide band chipset module in this application, can promote the accuracy of distance between wireless device and the electronic equipment, and then promotes WIFI transmitted power's accuracy to further reduce extra consumption. Moreover, the ultra-wideband communication is characterized in that 2ns pulses are used for communication, and the transmission rate is extremely high, so that the ranging can be completed in a very short time, the response time of power control is shortened, and the efficiency of power adjustment is improved.
Further, a second exemplary embodiment of a WIFI transmit power adjustment method is presented.
The electronic equipment also comprises a WIFI chipset module; referring to fig. 3, before step S11, the method further includes:
step S1, broadcasting a calibration signal through the WIFI chipset module;
and step S2, receiving a first device identifier fed back by the wireless device connected with the electronic device through WIFI.
Correspondingly, the response signal further includes a second device identifier, and after the step S12, the method further includes:
step S121, determining whether the number of second device identifiers included in the response signal is equal to the number of first device identifiers;
if the number of the second device identifications in the response signal is equal to the number of the first device identifications, step S13 is executed.
In this embodiment, the electronic device further includes a WIFI chipset module, and the WIFI chipset module can transmit a WIFI signal, and a frequency band of the WIFI signal may be ISM2.4G, ISM5G & 6G. When the electronic equipment starts the WIFI hotspot function, the electronic equipment controls the WIFI chipset module to transmit a broadcast calibration signal, the frequency band of the broadcast calibration signal can be set to ISM2.4G, and the frequency band is low in frequency and long in transmission distance.
After receiving the broadcast calibration signal, the wireless device connected to the electronic device WIFI feeds back the device identifier of the current wireless device to the electronic device, and it can be understood that the number of the wireless devices connected to the electronic device WIFI may be 0, 1, or multiple, and if the number of the wireless devices connected to the electronic device WIFI is multiple, the device identifier of the wireless device received by the electronic device is also multiple.
After the ultra-wideband chipset module broadcasts the ultra-wideband ranging signal, the wireless device receiving the ultra-wideband ranging signal feeds back a response signal to the electronic device, the response signal includes the device identifier of the current wireless device, it should be noted that, because the transmission distance of the ultra-wideband signal is often less than the WIFI signal, therefore, the number of the wireless devices receiving the ultra-wideband ranging signal may be less than the number of the wireless devices receiving the WIFI signal, that is, a wireless device far away from the electronic device can receive the WIFI signal and feed back the device identifier, it may not receive the ultra-wideband ranging signal because the distance is far away, therefore, it can not feed back the response signal of the ultra-wideband ranging signal.
Therefore, when the number of the second device identifiers included in the response signal is determined to be equal to the number of the first device identifiers, it is indicated that the wireless devices connected with the electronic device WIFI are both in the coverage range of the ultra-wideband ranging signal, and at this time, the distance between each wireless device and the electronic device can be accurately determined through the ultra-wideband ranging signal.
Further, referring to fig. 4, after step S121, the method further includes:
step S122, if the number of the second device identifiers included in the response signal is smaller than the number of the first device identifiers, determining the device identifier of the non-feedback response signal according to the first device identifier and the second device identifier;
and S123, controlling the electronic equipment to communicate with the wireless equipment corresponding to the equipment identifier without the feedback response signal according to the preset highest transmitting power.
In this embodiment, if the number of the second device identifiers included in the response signal is smaller than the number of the first device identifiers, it is described that some of the wireless devices connected to the electronic device WIFI are not within the coverage range of the ultra-wideband ranging signal, and at this time, the distances between the wireless devices and the electronic device cannot be accurately determined through the ultra-wideband ranging signal, so that the electronic device is controlled to communicate with the wireless devices corresponding to the device identifiers that do not feed back the response signal according to the preset highest transmission power. The user may set the preset maximum transmit power as needed, and this embodiment is not limited specifically.
The embodiment considers that the transmission distance of the ultra-wideband signal is often smaller than the WIFI signal, the situation that the distance between part of the wireless equipment and the electronic equipment exceeds the coverage range of the ultra-wideband ranging signal may occur, and corresponding electronic equipment transmitting power is set for the situation, so that all the wireless equipment connected with the electronic equipment WIFI can carry out normal data communication with the electronic equipment, and the stability and reliability of WIFI communication are improved.
Further, based on the foregoing embodiments, a third exemplary embodiment of a WIFI transmission power adjustment method is proposed.
Referring to fig. 5, after step S30, the method further includes:
step S41, when the electronic equipment is controlled to communicate with the wireless equipment for a preset time length according to the lowest transmitting power, whether the distance between the electronic equipment and the wireless equipment connected with the electronic equipment WIFI changes or not is determined;
step S42, if yes, re-determining a new minimum transmitting power between the electronic device and the wireless device according to the changed distance between the electronic device and the wireless device connected with the electronic device through WIFI, and controlling the electronic device to communicate with the wireless device according to the new minimum transmitting power.
In this embodiment, whenever the electronic device and the wireless device communicate with each other for a preset time according to the corresponding minimum transmission power, the ultra wideband chipset module or the bluetooth module is used to determine the distance between the electronic device and the wireless device again, and determine whether the distance between the electronic device and the wireless device changes, if the distance between the electronic device and the wireless device changes, the new minimum transmission power between the electronic device and the wireless device is determined again according to the changed distance and the determination method of the minimum transmission power in the foregoing embodiment, and then the electronic device is controlled to communicate with the wireless device according to the new minimum transmission power.
It can be understood that, if the distance measurement signal is sent to the wireless device through the ultra-wideband chipset module or the bluetooth module to determine the distance between the electronic device and the wireless device again, the wireless device does not feed back a response signal, which indicates that the distance between the wireless device and the electronic device exceeds the coverage of the ultra-wideband distance measurement signal, and at this time, the electronic device can be controlled to communicate with the wireless device according to the preset highest transmission power.
Further, if the distance between the electronic device and the wireless device is not changed, the transmission power of the electronic device during communication with the wireless device is not adjusted.
Through the mode, the lowest transmitting power of the electronic equipment for communicating with the wireless equipment is adjusted in time when the distance between the wireless equipment and the electronic equipment is changed, so that the extra power consumption caused by communication with higher transmitting power when the distance between the wireless equipment and the electronic equipment is reduced is avoided, and meanwhile, the situation that the wireless equipment cannot receive communication data because communication is carried out with lower transmitting power when the distance between the wireless equipment and the electronic equipment is increased can also be avoided.
