ICS Repeater
|
|
The 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/DCS/PCS 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.
As per operator¡¯s working frequency, two types of RFR are available:
The band-selective function can amplify all signals in the whole band (bandwidth is customized).
The channel-selective function can amplify only the signals transmitted by the customized 1 (2 or 4 or 8) channel

Specifications
Features
- Aluminum-alloy casing with IP65 protection has high resistance to dust, water and corroding
- Highly selective channel selector can process 8 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
- 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 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, ¡
