Digital ICS Repeater 16 channel

Descripción del producto

The ICS Repeater (Interference Cancellation System) is a new kind of single-band RF repeater that can automatically detect and cancel the interference signals caused by oscillation of RF feedback between the Donor and Coverage Antennas in real time by adopting DSP (Digital Signal Processing) technology. It can continuously and stably cancel the interference signals and be adapted to any changes in the surrounding RF environment (including fixed and mobile objects).

Like the RF repeater, the ICS Repeater is working as a relay between the BTS and mobiles. It picks up the signal from the BTS via the Donor Antenna, linearly amplifies the signal and then retransmits it via the Coverage Antenna (or the Indoor Signal Distribution System) 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 ICS Repeater are available:

Band-Selective ICS Repeater: to amplify all signals in the whole band (bandwidth is customized);
Channel-Selective ICS Repeater: to amplify only the signals transmitted in customized channels.

Features
Aluminum-alloy casing has high resistance to dust, water and corroding;
Real-time cancellation of interference signal (incl. multi-path fading, feedback signal);
ICS function to prevent self-oscillation, enhance gain and coverage range, and reduce isolation requirement between donor antenna and coverage antenna;
Highly selective digital 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***2 ports provide links to a notebook for local supervision and 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
