Dual Band GSM900 & Dcs1800 RF Repeater, Mobile Signal Amplifier

Dual Band GSM900 & DCS1800 RF Repeater, Mobile Signal Amplifier

Model: VR-4090-GD
The GSM&DCS 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&DCS1800 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.
Features
N Band-Selective RF Repeater: To amplify all signals in the whole band (bandwidth is customized);
N Aluminum-alloy casing with IP65 protection has high resistance to dust, water and corroding;
N Highly selective channel selector can process 12 channels simultaneously;
N No interference to BTS by adopting linear amplifier with high gain and low noise;
N Adopting filter with highly selectivity and low insertion loss eliminates interference between uplink and downlink;
N 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.
