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.

Product Description

Technique supporting:

1. If still no signal receipt after activated repeater,please check if outdoor antenna point to signal tower or elsewhere have strong signal and check if strength achieve -70dBm.

2. If cannot call out,please adjust the direction of outdoor antenna.

3. If the strength is not steady,please check if outdoor and indoor antennas are too close;please ensure the outdoor antenna and indoor antenna have distance of 20meters at least,with a wall between and not in a same horizontal line.

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.
