A frequency shifting repeater consists of two different elements, a master unit close to the BTS and at least on remote unit close to the area to be covered. The master unit amplifiers the channel from the BTS and shifts them to different channel. In the remote, the shifted channels from the master unit will be transferred back to the original channels and amplifier. This is valid for the downlink signal as well as for the uplink signal. Due to reasons of receives and transmit different frequencies, frequency shifting repeater overweighs other repeaters in its larger gain achievement (97dB) and more extended coverage area. It is often used in complex electromagnetic environment, fiber optic unreachable areas and large gain required situation.
