<p>A system operates to adaptively control the coverage area of an on frequency repeater. First RF signals received from a transceiver (such as a base station, or a subscriber's wireless communications device) are detected using a broadband detector, narrowband down converter and detector, and these detected signals are monitored by a micro controller. The micro controller operates, under control of suitable software implementing an Adaptive Control Algorithm, to adjust the ERP of second RF signals transmitted to the transceiver to thereby control the coverage area of the repeater, and maintain a substantially constant power level of the second RF signals received by the transceiver.</p> |
