A method and apparatus for implementing a protocol for controlling transmitter power in a wireless LAN. The LAN is assumed to include a number of nodes, each node including a transmitter and a receiver for communicating information between computers located at the node. To initiate the protocol, the transmitter of a data sending node first transmits a signal including a transmitter power signal to each of the receivers of the data receiving noes. The information contained in the transmitter power signal may be transmitted in one of the fields of the data packet of the signal. The receivers of the data receiving nodes individually transmit power control feedback signals back to the transmitter of the data sending node. Information in each of the power control feedback signals may occupy a field in the data packet transmitted from the receiver to the transmitter of the data sending node. Preferably, the transmitter power signal indicates the radiated power level of the transmitter and each of the power control feedback signals comprises an instruction instructing the transmitter to adjust its radiated power. Upon receipt of these feedback signals, the transmitter preferably adjusts its radiated power accordingly, balancing the feedback received.
