2) Reduce radiation from Cell Phone;
3) Easy to install;
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.
GSM850 broadband cell phone wireless RF Repeater Function:
- Waterproof chassis suitable for indoor and outdoor service;
- Metal cavity filter technology inside, which gives wider receiving and sending separation, better gain flatness, higher stability, and lower noise figure;
- lFull-duplex & dual-port design, and built-in power supply, making it convenient for installation;
- Allowing for continuous gain adjustment and gain contrast;
- ALC technology used to provide auto amplitude fixing.
GSM850 broadband cell phone wireless RF Repeater Application:
Outdoor: Airports, Tourism Regions, Golf Courses, Tunnels, Factories, Mining Districts, Villages
