MIFI DEVICE AND POWER ADJUSTMENT METHOD AND SYSTEM THEREFOR, AND ELECTRONIC DEVICE

Disclosed in the present disclosure are a MiFi device and a power adjustment method and system therefor, and an electronic device. The method comprises: for each terminal device which is connected to a MiFi device, testing a corresponding information transmission rate between the MiFi device and the terminal device at each WiFi transmit power; and for each terminal device, according to each information transmission rate, determining the lowest WiFi transmit power transmitted by the MiFi device to the terminal device. By means of the embodiments of the present disclosure, the WiFi transmit power of a MiFi device can be automatically adjusted, such that the power consumption is reduced and the endurance time is prolonged without affecting an information transmission rate. Sont divulgués dans la présente divulgation un dispositif MiFi et un procédé de réglage de puissance et un système associé, et un dispositif électronique. Le procédé comprend les étapes suivantes : pour chaque dispositif terminal qui est conne
