Abstract

An RF repeater arrangement for exchanging transmit and receive signals between a handset and a base station in a wireless telephone system automatically componsates for attenuation losses. The RF repeater arrangement includes first and second RF repeater parts connected by a signal conduit, the first part interfacing with the base station and having a signal level detector for detecting the level of the transmit signal, a microprocessor controller for quantizing and encoding the signal level detected by the level detector and a modulator for modulating the signal level data and outputting the modulated signal level data to the signal conduit. The second part has a demodulator for demodulating the signal level data, an amplifier for amplifying the transmit signal, a signal level detector for detecting the level of the transmit signal amplified by the amplifier, and a microprocessor controller for comparing the demodulated signal level data and the amplified signal level and correspondingly adjusting the amplifier to counteract attenuation of the transmit signal and the receive signal along the signal conduit.
