20W CDMA800MHz BTS Repetidor Air Coupling Frequency Shifting Repeater

Product Detail

: The Frequency Shift Repeater (FSR) is designed to solve problems of weak mobile signal, which can expand more coverage than RF repeater and reduce investment for the areas where fiber optic cable is not available.The whole FSR system consists of two parts: Donor Unit and Remote Unit. They transparently convey and amplify the wireless signal between the BTS (Base Transceiver Station) and mobiles via RF wave at different frequency from the BTS.The Donor unit receives the BTS signal via a direct coupler closed to the BTS (or via open air RF transmission through the Donor Antenna), then converts it from the working frequency to the link frequency, and transmits the amplified signal to the Remote Unit via the Link Antennas. The Remote Unit will reconvert the signal to the working frequency and provide the signal to the areas where network coverage is inadequate. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.

Mainfeature: Features: 1,Best solution to eliminate mutual interference due to sharing the same frequency; 2,No stringent isolation requirement for antenna installation; 3,Easy to choose installation site; 4,The Remote Unit can be installed out of the BTS coverage; 5,RS-232 ports provide links to a notebook for local supervision and to the built-in wireless modem to communicate with the NMS (Network Management System) that can remotely supervise repeater’s working status and download operational parameters to the repeater. 6,Aluminum-alloy casing has high resistance to dust, water and corroding;
