Introduction:
The Repeater captures the reliable cellular signal you have outdoors and rebroadcasts it indoors, up to 2,500 square feet,so you can enjoy clearer,faster and more reliable service without interruption. Remember,coverage varies based on outdoor signal level,building construction,and antenna placement.Coverage in adjoining rooms will be reduced by walls and ceiling/floors.

Note:
1.The frequency is the most important thing to choose a signal booster, because the GSM,3G or 4G means different frequency in different countries.
2.The main unit would get warm after it has been worked for 30 minutes.If it does not get hot, please send emails to us.
3.If there is still no signal after you install the booster, please adjust the outdoor antenna.You should get 2-3 bars of stable signal in the location where the outdoor antenna is fixed in,or the booster can't work. Outdoor antenna should be installed 2 meters higher of your roof or put it on a high open place,so it can get better reception.
4.If you can get full bars signal after you install the booster,but can't make calls, please make sure that Outdoor and Indoor antenna are separated by wall to avoid interference,putting them as far as 10 meters.
