Dual-Band GSM900 / WCDMA2100 RF Amplifier , Cell Phone Signal Repeater
Model: VR-4390-GW
Product Instructions:
The GSM&WCDMA Dual-Band RF Repeater is designed to provide a more cost-effective solution than adding a new Base Transceiver Station (BTS) to improve signal coverage and communication quality in GSM900&WCDMA2100 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 weak/blind coverage area. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.
Product Features:
- Band-Selective RF Repeater: to amplify all signals in the whole band (bandwidth is customized);
- Aluminum-alloy casing with IP65 protection has high resistance to dust, water and corroding;
- Highly selective channel selector can process 12 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 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.
Applications:
To expand signal coverage or fill signal blind area where GSM and WCDMA 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, etc.
