Communication power control method, communication equipment and communication system based on RSSI

Abstract

In current applications, when a short distance wireless transceiver chip transmits and receives data, transmitting power and receiving power are fixed, usually in order to achieve the purpose of signal communication, the data are transmitted and received by utilization of maximum power / maximum gain, in actual applications, under most conditions, the data are not needed to be transmitted and received by utilization of the maximum power / maximum gain, and extremely large waste of power consumption is caused. The invention provides a method dynamically controlling the transmitting power and the receiving power of the transceiver chip, communication equipment and a communication system based on an RSSI, the transmitting power and the receiving power are further lowered according to the actual applications, the power consumption is reduced, and the service life of a battery is prolonged.

Description

technical field [0001] The invention relates to a method for reducing transmitting and receiving power through RSSI value in wireless communication, especially in short-distance wireless communication, so as to save power consumption. Background technique [0002] In short-distance wireless communication, power consumption has always been a difficult problem restricting its application. Manufacturers always try their best to reduce power consumption, improve product competitiveness and meet the power consumption requirements of products entering the market. [0003] In the current short-distance wireless communication, among the main bodies of the communication parties, each main body is mainly composed of a wireless transceiver chip, a main control chip and some peripheral devices. Reducing power consumption is mainly to use low-power devices, such as low-power wireless transceiver chips, low-power main control chips, etc. At the same time, based on the control of the main ...

Problems solved by technology

[0004] In the above method, when the transceiver chip transmits and receives data, the transmission and reception power is fixed. Usually, in order to achieve the purpose of signal communication, the maximum power / maximum gain is used for transmission and reception. In practical applications, in most Under the circumstances, it is not necessary to use the maximum power / maximum gain to transmit and receive, so it causes a great waste of power consumption
