Patent ID: 7215933

Claim:
A radio frequency (RF) transmitter power control system for a transmitter of a wireless local area network device, comprising: a transmitter that transmits RF signals; a sensor that detects at least one of amplitude and power of said RF signals and that generates a sensed signal; and a gain adjuster that compares said sensed signal to a threshold signal and that adjusts at least one of a gain and an output power level of said transmitter, wherein said RF transmitter power control system is packet-based and wherein said sensor senses said one of said amplitude and said power of a first packet without adjusting said at least one of said amplitude and said power during said first packet and said gain adjuster adjusts said at least one of said gain and said output power level of said transmitter for a subsequent packet based on said at least one of said sensed amplitude and said sensed power during said first packet.
