1. A service-area repeater for deployment in a service area in order to provide capacity supplied by a base station located remotely from the service-area repeater in the service area, the service-area repeater comprising:
downlink circuitry configured to receive, via a donor antenna coupled to the service-area repeater, transformed radio frequency downlink signals transmitted from the base station or a base-station repeater, the base station transforming original radio frequency downlink signals or the base-station repeater transforming original radio frequency downlink signals received from the base station in order to produce the transformed radio frequency downlink signals that cannot be detected by user equipment outside the service area;
wherein the downlink circuitry comprises a first signal transformation circuit configured to de-transform the received transformed radio frequency downlink signals in order to generate downlink signals that are not transformed;
wherein the downlink circuitry further comprises a first frequency correction circuit configured to apply a frequency correction to the downlink signals to produce corrected downlink signals; and
wherein the downlink circuitry is further configured to wirelessly transmit the downlink signals via a coverage antenna to any user equipment in the service area.
