The GSM 900/1800 Hybrid 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 GSM
900MHz and 1800MHz system. And its easy installation and maintenancecan 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.
As per operator’s requirement for working frequency, two types of RFR are available:
Aluminum-alloy casing with IP65 protection has high resistance to dust, water and corroding
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 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 signal is weak or unavailable.
Indoor: Hotels, exhibition centers, basements, shopping malls, offices, parking lots, …
