Definitions
- the transmitting end when the transmitting end and the receiving end communicate through WiFi, the transmitting end obtains the WiFi status parameters of the receiving end in real time, wherein the WiFi status parameters are used to indicate the current working status of the WiFi channel of the receiving end, and in addition
- the working main frequency of the receiving end is used to indicate the working main frequency state of the main control system of the current receiving end; the comparison difference between the WiFi state parameter and the preset parameter is determined, and a control signal is generated according to the comparison difference; the described The control signal is sent to the receiving end; the receiving end changes the main frequency of work according to the control signal; for example, when it is found that the WiFi channel of the receiving end is working lower than the preset rate state, the transmitting end sends a control signal to the receiving end through the WiFi channel , so that the receiving end reduces the main frequency of the system, thereby reducing the interference to the WiFi channel, and achieving the effect of improving the performance of the WiFi receiving end.
- FIG. 2 is a schematic flowchart of a method for improving WiFi performance in an embodiment of the present application.
- FIG. 1 is a schematic structural diagram of a WiFi communication device in a hardware operating environment involved in the solution of the embodiment of the present application.
- the rate of the receiving end is often unsatisfactory when the transmitting end is in good condition.
- the wireless frequency band generated by the working frequency of the receiving end system and the frequency generated by WiFi communication interfere with each other. The existence of these interferences leads to the degradation of WiFi performance, deterioration of signal quality, and error codes in received information. rate increase etc.
- the contrast difference is a positive value
- the contrast difference is a negative value
- the comparison difference is used to determine the level of the current WiFi working rate of the receiving end.
- the comparison difference is a positive value, it indicates that the current WiFi working rate of the receiving end is higher than the preset parameter value, so the system operation of the receiving end can no longer be restricted. Efficiency, so the main frequency control signal is generated and sent to the receiving end; on the contrary, when the comparison difference is negative, it means that the current WiFi working rate of the receiving end is lower than the preset parameter value, so it is necessary to limit the system working efficiency of the receiving end at this time, so generate Increase the main frequency control signal to send to the receiving end, reduce the interference to the WiFi channel by reducing the working main frequency of the receiving end system, and achieve the effect of improving the performance of the WiFi receiving end.
- the transmitter and receiver start and establish a WiFi connection
- RSSI indicates received signal strength
- Noise indicates noise intensity
- SNR indicates signal-to-noise ratio
- BSS indicates the number of surrounding signals
- Kn, Kr, Kb, and Ks are proportional constants
- the sum of Kn, Kr, Kb, and Ks is 1 .
- the WiFi state parameters include RSSI indicating received signal strength, Noise indicating noise intensity, SNR indicating signal-to-noise ratio, and BSS indicating the number of surrounding signals.
- Four parameters are calculated by correspondingly weighting the four parameters.
- a control signal for reducing the main operating frequency of the system is generated; when the WiFi state parameter is smaller than the second preset value, a control signal for increasing the main operating frequency of the system is generated.
- SNR is calculated by obtaining useful power signals and useless power through wireless chips.
- an embodiment of the present application further provides a storage medium, which is a computer-readable storage medium, on which is stored a program for improving WiFi performance. Steps in the method of improving WiFi performance.

Abstract
Un procédé d'amélioration des performances Wi-Fi, et un dispositif de communication Wi-Fi et un support d'enregistrement sont divulgués dans la présente demande. Le procédé pour d'amélioration des performances Wi-Fi comprend les étapes suivantes consistant à : acquérir un paramètre d'état Wi-Fi d'une extrémité de réception ; déterminer une différence de contraste entre le paramètre d'état Wi-Fi et un paramètre prédéfini ; générer un signal de commande selon la différence de contraste ; envoyer le signal de commande à l'extrémité de réception ; et modifier, par l'extrémité de réception, une fréquence dominante de fonctionnement selon le signal de commande, de telle sorte que la fréquence dominante de fonctionnement de l'extrémité de réception correspond au paramètre d'état Wi-Fi. Au moyen du procédé pour d'amélioration des performances Wi-Fi divulgué dans la présente demande, les problèmes de l'état de la technique d'un processus d'utilisation fastidieux et de coûts relativement élevés en raison du fait que les performances Wi-Fi sont améliorées par montage d'un dispositif externe peuvent être résolus.
