ABSTRACT:
A cellular communication device for a cellular communication network which includes a radio-frequency (RF) transmitter for transmitting an RF signal at an output power level to one or more other devices in the cellular communication network; an RF receiver for receiving an RF signal from one or more other devices in the cellular communication network; and a gain control circuit for sampling the output power level to obtain a sampled output power level signal, digitizing the sampled output power level signal, and adjusting a gain of the RF transmitter based on the digitized sampled output power level signal in order that the output power level of the RF transmitter approaches a predefined output power level. The gain may also be adjusted in response to the Received Signal Strength Indicator (RSSI) in order to conserve battery power.
