Detailed Product Description

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:

To expand signal coverage or fill signal blind area where signal is weak or unavailable.

The ICS Repeater is mainly applicable to such case:

In comparison with standard RFR (RF Repeater), FSR (frequency shift repeater) and FOR (fiber optic repeater), the ICS Repeater has the following benefits and disadvantages:
