The Dual-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 the dual-band system. And its easy installation and maintenance can help carriers get fast returns.
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:
- Aluminum-alloy casing with IP65 protection has a high resistance to dust, water, and corroding
- Low interference to BTS by adopting a linear amplifier with high gain and low noise
- Adopting filter with high selectivity and low insertion loss eliminates interference between uplink and downlink
- The USB 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 the repeater's working status and download operational parameters to the repeater
Application Diagram To expand signal coverage or fill the signal blind area where the 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, …
