33dBm GSM&DCS 900&1800 2W ICS Repeater
Main Features :
◇ 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;
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.
