40dBm GSM 900mhz ICS band selective Repeater 10W
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) .
Main Features OF ICS Repeater
◇ 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 12 channels simultaneously；
◇ Network manage remote monitoring function；
◇ Integrated technique with reliable performance;
◇ Local and remote monitoring (optional) with automatic fault alarm &remote control;
◇ Weatherproof design for all-weather installation;
KINGTONE Ics repeater Applications
To expand signal coverage of fill signal blind area where signal is weak
or unavailable.
Outdoor: Airports, Tourism Regions, Golf Courses, Tunnels, Factories, Mining Districts, Villages etc.
Indoor: Hotels, Exhibition Centers, Basements, Shopping
Malls, Offices, Packing Lots etc.
It is mainly applicable to such case:
The repeater can find an installation place which can receive pure BTS signal at strong enough level as the Rx Level in repeater site should be more than ‐70dBm;
And can meet the requirement of antenna isolation to avoid self‐oscillation.
