Umts / Gsm1800 Rf Repeater Rfr Is Designed To Improve Signal Coverage And Communication Quality

The UMTS/GSM1800 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 UMTS & GSM 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:

 Aluminum-alloy casing with IP65 protection has high resistance to dust, water and corroding
 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

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, …
Indoor: Hotels, exhibition centers, basements, shopping malls, offices, parking lots, …
