Product Description:

The CDMA In-Band 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 or dedicated cable is not allowed.

The system consists of two parts: Donor Unit and Remote Unit. The Donor Unit receives the BTS (Base Transceiver Station) signal via open air RF transmission or direct coupler closed to BTS, then converts it from the working frequency to the link frequency that is inside the working band, and transmits the amplified signal to the Remote Unit that will reconvert the signal to the working frequency and provide 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.

Features:

 Aluminum-alloy casing with IP65 protection has high resistance to dust, water and corroding

 Best solution to eliminate mutual interference due to sharing the same frequency

 No stringent isolation requirement for antenna installation

 Easy to choose installation site

 RS-232 port provides a link to a notebook for local supervision or 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

Application:

To expand signal coverage or fill signal blind area where CDMA signal is weak or unavailable.

Outdoor: Airports, tourism regions, golf courses, tunnels, factories, mining districts, villages, …

Indoor: Hotels, exhibition centers, basements, shopping malls, offices, parking lots, …
