gsm900 mobile signal booster 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.
