Problems solved by technology

[0004] However, the transmission power of the signal is attenuated during the transmission process. When the signal is sent with the adjusted transmission power value, when the signal reaches the WIFI access point, it may be lower than the receiving sensitivity of the WIFI access point itself, which will cause WIFI access. point cannot correctly demodulate the received signal, resulting in a high bit error rate

Abstract

An embodiment of the invention discloses a WIFI transmitting power regulation method, terminal and system. The WIFI transmitting power regulation method includes the following steps: a WIFI receiving terminal receives a WIFI signal sent by a WIFI transmitting terminal, and detects a signal intensity value of the received WIFI signal; the WIFI receiving terminal determines an indicated transmitting power value of the WIFI transmitting terminal according to the received signal intensity value of the WIFI signal sent by the WIFI transmitting terminal; and the WIFI receiving terminal sends the indicated transmitting power value to the WIFI transmitting terminal, so that the WIFI transmitting terminal adopts the indicated transmitting power value to send the WIFI signal to the WIFI receiving terminal. By adoption of the WIFI transmitting power regulation method provided by the invention, the WIFI receiving terminal can correctly demodulate the received WIFI signal sent by the WIFI transmitting terminal, thereby reducing an error rate.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, terminal and system for adjusting WIFI transmission power. Background technique [0002] At present, most terminals support WIFI (Wireless Fidelity, wireless local area network) technology. The WIFI module can connect the terminal to the network through radio waves within an effective range. This WIFI access method is favored by more and more users. [0003] When the terminal sends data, it generally transmits with a fixed power, and the power value cannot be adjusted. In the prior art, the terminal is based on the RSSI (received signal strength index, the RSSI index of the WIFI access point can be mapped to the receiving sensitivity of the WIFI access point.) according to the received signal of the WIFI access point. The mapping table between the RSSI value of the signal of the WIFI access point and the transmission power or calculate the transmission p...
