Application Scenarios

All specifications of PA can be customized based on customer requirement.

The repeater makes the signal stronger in places with poor signal coverage such as:
1. Underground areas: basements, parking lots, tunnels, subway, suburb;
2. Other places where cellular signal is shielded by metal or concrete walls: offices, supermarkets, cinemas, hotels, building;
3. Places distant from the BTS like private houses.

1. Fix up outdoor antenna reception on housetop and point to signal tower.

2. Connect outdoor antenna to "BTS" Port on the Booster through cable. 

3. Connect indoor antenna(s) to "User" or "Mobile" Port on the Booster directly or through cable.also.

4. Plug Power Adaptor into AC power socket and finish installation.

Problem Support;
1. If still no signal receipt after activated booster, please check whether outdoor antenna point to signal tower, or the place you install outdoor antenna have strong signal, it need be 3bar signal or more.
2. If can not call out, please adjust the direction of outdoor antenna.
3. If strength is not steady, please check whether outdoor and indoor antennas are too close. Please ensure the outdoor and indoor antenna have max distance, with a wall between and not in a same horizontal line.
