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.
