Abstract

A wireless transmission apparatus and optimization method for transmission quality are provided. The wireless transmission apparatus comprises an antenna, a variable gain and switch circuit, a driving chip and a control circuit. The variable gain and switch circuit is coupled electrically between the antenna and the driving chip. A RSSI is outputted to the control circuit by the driving chip and the control circuit is coupled with the driving chip. The RSSI is compared with a predetermined value by the control circuit, and a control signal is outputted to the variable gain and switch circuit by the control circuit. Gain of the next transmitting signal is defined by the variable gain and switch circuit in response to the control signal for increasing the transmission distance and improving the receiving sensitivity of the wireless transmission apparatus.
