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, …
