WCDMA RF Repeater
The WCDMA RF Repeater (RFR) is designed to provide a more cost-effective solution than adding a new Base Transceiver Station (BTS) to improve signal coverage and communication quality is CDMA system. And its easy installation and maintenance can help carrier get fast return.
The repeater is working as a relay between the BTS and mobiles. It receives the low power signal from BTS via the Donor Antenna, linearly amplifies the signal and then retransmits it via the coverage Antenna to the weakblind coverage area. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.
The channel selective function can amplify only the signals transmitted by the customized 1 or 2 channels.
Features
- Aluminum-alloy casing has high resistance to dust, water and corroding;
- Highly selective digital channel selector can process 2 channels simultaneously;
- No interference to BTS by adopting linear amplifier with high gain and low noise;
- Adopting filter with highly selectivity and low insertion loss eliminates interference between uplink and downlink;
- 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 repeaters working status and download operational parameters to the repeater.
Application
To expand signal coverage or fill signal blind area where GSM 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,
