43dBm GSM&DCS 900&1800 dual band ICS wide band Repeater
Kingtone GSM 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)
Technical features of ICS repeater
◇ Waterproof chassis suitable for indoor and outdoor service;
◇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；
◇ High selectivity digital band filter eliminate out of band interference ；
