Gsm-r In-band Frequency Shifting Repeater
Posted at: Offers to Sell and Export | Posted on: Monday 25 January 2010 2:13 am | Poster last visit: Monday 16 August 2010 |
Product Description:
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
