Abstract: A system operates to adaptively control the stability of an on-frequency repeater. A unique signature is imposed on RF signals transmitted by the repeater, and RF signals received by the repeater analyzed to detect signal components corresponding to the signature. The signature and the detected signal components are correlated by a micro-controller, which operates in accordance with an Adaptive Control Algorithm to adjust the ERP of RF signals transmitted by the repeater to limit signal leakage and thereby control the stability of the repeater.

Abstract: An intelligent gain controller operates to control the gain in each one of wideband uplink and downlink signal paths. Weak desired signals, within each wideband signal path, are detected using a narrowband down converter and detector, and these desired signals monitored by the micro controller. Based on the monitored signals, the micro controller operates, under control of suitable software implementing an Adaptive Control Algorithm, to adjust the gain in each of the uplink and downlink paths in order to dynamically optimize performance.

Abstract: An adaptive personal repeater transparently mediates signaling between a wireless communications device (WCD) and a wireless communications network. The repeater includes a Directional Donor Unit (DDU) and a Subscriber Coverage Unit (SCU). The DDU maintains a network link with a transceiver (base station) of the wireless communications network. The SCU maintains a local link with the WCD within a personal wireless space of the repeater. The SCU generally includes, means for detecting respective uplink and downlink channel frequencies of the wireless communications device, and control means for controlling at least the SCU to selectively receive and transmit signals within the detected uplink and downlink channel frequencies. Total system gain is divided between the DDU and the SCU, so that a separate gain and system control unit is not required. This division of system gain also enables high-performance on-frequency repeater functionality to be obtained without the use of high-cost components.

Abstract: 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.
