Abstract
A master transceiver automatically lowers its transmit power level at intervals until a slave transceiver no longer accurately receives the transmitted data. When the master detects an inaccurate transfer of data, the master incrementally increases the transmit power level until it is determined that there has been an accurate transfer of data. At that time, the master transmits an acknowledge signal to the slave. Since the automatic power adjust routine is performed using the transmitted data from the master and the error control information transmitted by the slave, there is little or no overhead used by the power adjust routine. Simple control circuitry can be used to carry out the functions.
