37dBm Tri-Band GSM900 / Dcs1800 / WCDMA2100 , RF Repeater / Signal Amplifier


Model: VR-4390-GW


Product Instructions:


      The GSM&DCS&WCDMA Tri-Band 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 in GSM900&DCS1800&WCDMA 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 process1 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 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 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.
