Abstract

The invention discloses a method, a device and a system of adjusting transmit power automatically, belonging to the technical field of communications. The method of adjusting the transmit power automatically comprises the steps of receiving a radio frequency signal from a first terminal; detecting signal strength indication information of the radio frequency signal; determining whether the signal strength of the radio frequency signal is within a signal strength range realizing stable communication of a second terminal; and if the signal strength is higher than a signal strength highest threshold realizing stable communication of the second terminal, lowering a current transmit power of the second terminal. The existing radio device wastes power when transmitting a signal with a fixed power. Through adoption of the method, device and system of adjusting transmit power automatically, the above problem is solved. The transmit power is adjusted automatically, a user does not need to operate manually, so that the use experience of the user is improved, and the technical effect of saving power is achieved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for automatically adjusting transmission power. Background technique [0002] The current radio equipment such as mobile radios, vehicle radios, and repeaters are mostly fixed power. When in use, the default is to continuously transmit signals at the maximum power (that is, fixed power). However, when the distance between two operating radio equipment is relatively close, use High power leads to power oversupply and there is a problem of radio equipment draining power. At the same time, some radio devices on the market have a limited number of power levels, but adjusting the power level increases the complexity of user operations and greatly reduces the user experience. Contents of the invention [0003] In order to solve the power consumption problem existing in existing radio equipment transmitting signals with fixed power, embodime...
