SHENZHEN GUA NRI TECHNOLOGYCO. , LTD. Subject to change without prior notice Th e GSM 900/18 00 H ybrid RF Rep eater (RFR) is d esig ned to p rovid e a more cost-effective solution than adding a new Base Transceiver Station (BT S) to improve sign al cover age and communication quality in GSM 900MHz and 1800MHz sys tem. A nd its easy installation an d m aintenance can help carrier get fast return. Th e rep eater is work ing as a rel ay b etwe en the BT S an d mobil es. It receives the low-power signal from BTS via the Don or Anten na, linearly amp lifies the s ign al and then r etran smits it via th e Cover age Antenna to the weak/blind coverage area. And the mobile signal is also amplified and retransmitted to the BTS via the opp osite direction. As per oper ator’ s r equirem ent for work ing frequency, two types of RFR are av ailab le: Aluminum-alloy casing with IP65 protection has high resistance to dust, water and corroding Highly s elective channel selector can pr ocess 2 chann els si mul taneously No interference to BTS by adopting linear amplifier with high gain and low noise Ad opting f ilter with highly selectivity and low insertion loss eliminates interference between uplink and downlink 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 To expand signal coverage or fill signal blind area where signal is weak or unavailable.
