The Frequency Shifting Repeaters system (FSR) consists of two parts: Donor Unit and Remote Unit. The Donor Unit receives the downlink signal from base station and shifts it to relevant channel, then transmits to the Remote Unit via relay antenna. The Remote Unit reconverts the received signal to the primary channel and covers the whole coverage areas. The Remote Unit receives the mobile signal from coverage areas and also shifts it to relevant channel, then transmits to the Donor Unit via relay antenna. The Donor Unit will reconvert the signal to uplink signal of the primary channel then send to the base station. Thereby availably expand and fill signal area where mobile communication coverage is blind, enhance communication quality.
