Abstract
A method and apparatus are disclosed for automatic transmit power variation in a wireless communication system. A wireless communication device according to the present invention includes a dynamic transmit power controller that adapts a transmit power level based on a transmission rate of the data. One aspect of the dynamic transmit power controller selects a maximum allowable power level that is based on limits specified for a given region and frequency band, or a maximum directional gain of an antenna (or both). Another aspect of the dynamic transmit power controller selects a maximum capable power level that is based on the transmission rate, frequency band, or characteristics of a transmitter output amplifier (or a combination of the foregoing). Generally, the transmit power level is selected based on a minimum of the maximum allowable power level and the maximum capable power level.
