ABSTRACT:
A local transmitter power control system for a radio frequency transmitter of a wireless local area network device includes a transmitter that transmits RF signals. A sensor detects at least one of amplitude and power of said RF signals and generates a sensed signal. The gain adjuster includes a comparator that receives an amplitude signal and/or a power signal detected by the sensor. The comparator compares the amplitude and/or power to the threshold signal. The gain of the transmitter is adjusted accordingly.
