Abstract: An communication system equipped for automatic monitoring and adjustment of the transmitted power at both ends of a communications link to maintain the minimum required transmit power for reliable communication and to minimize the potential of interference with other communications links. A preferred embodiment of the invention is a millimeter wave system, operated level in the 71 to 76 GHz range. A received signal at one end of a communication link is used to adjust the power transmitted from the other end of the link in such a way as to maintain the received signal level within a desired range. If the received signal decreases below the desired range, the transmitted power is turned up, to maintain the link reliability and low Bit Error Rate (BER). If the received signal increases above the desired level, the transmitted power level is turned down, to reduce the potential for interference to other links.
