Key Specifications/Special Features:

GSM-R In-band frequency shifting repeater consists of two different

elements, a master unit close to the BTS and at least one remote unit close to the area to be covered. The master unit amplifies the channel from the BTS and shifts them to different channel. In the remote uint, the shifted channels from the master unit will be transferred back to the original channels and amplified. This is valid for the downlink signals as well as for the uplink signals. Due to reasons of receives and transmit different frequencies, GSM-R In-band frequency shifting repeater overweights other repeaters in its larger gain achievement (97+/-3dB) and more extended coverage area. It is often used in complex electromagnetic environment, fiber optic unreachable areas and large gain required situation
