Selling Point


1. Intelligent to guide the installation with LCD


2. Real time display the signal strength.


3. Automatic dormancy when no user make the calling


4. Automatic alarm when installation mistake and provide the according solution


5. Automatic adjust the system gain to avoid the repeater self-excitation


6. Initiative reminding when the device was damaged.



The repeater makes the signal stronger in places with poor signal coverage such as:


1) Underground areas: basements, parking lots, tunnels;


2) Other places where cellular signal is shielded by metal or concrete walls: offices, supermarkets, cinemas, hotels;


3) Places distant from the BTS like private houses.
