Dual-Band RF Repeater
MODEL:
RPT873 (GSM 900 & 1800) / RPT243 (GSM900 & WCDMA) /
RPT203 (GSM1800 & WCDMA)
The Dual-Band RF Repeater (RFR) is the kind of RF repeater that can simultaneously work in two wireless systems. It transparently conveys and amplifies the wireless signal of two systems respectively between the BTS (Base Transceiver Station) and mobiles.
The Dual-Band RFR is working as a relay between the BTS and mobiles. It picks up the signal from the BTS via the dual-band Donor Antenna, linearly amplifies the signal and then retransmits it via the dual-band Coverage Antenna (or the dual-band Indoor Signal Distribution System) to the weak/blind coverage area. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.
As per operator’s requirement for working frequency, two types of Dual-Band RFR are available:
- Band-Selective Dual-Band RF Repeater: to amplify all signals in the whole band (bandwidth is customized);
- Channel-Selective Dual-Band RF Repeater: to amplify only the signals transmitted in the customized 1 to 2 channels.

Specifications
Features
- Aluminum-alloy casing has high resistance to dust, water and corroding;
- AGC (automatic gain control) function to prevent self-oscillation;
- Highly selective 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 repeater’s working status and download operational parameters to the repeater.
Application
To expand signal coverage or fill signal blind area where signal is weak or unavailable.
- Outdoor: Airports, tourism regions, golf courses, tunnels, factories, mining districts, villages, highways…
- Indoor: Hotels, exhibition centers, basements, shopping malls, offices, parking lots, …
The Dual-Band RFR is mainly applicable to such case:
- The area to be covered requires to improve signal coverage of both wireless system;
- The repeater can find an installation place which can receive pure BTS signal at strong enough level and can meet the requirement of isolation to avoid self-oscillation;
- And the distance between the BTS and the area to be covered is 2km around.
