How Booster/Repeater Works?

Repeaters are designed to fulfill the idea of one and main principle: to fill the areas with the weak or bad signal and to amplify these low signals in order to provide you with the communication suitable for you.

Steps that describe the work of Repeater.

1) The outside antenna receives the signal from the nearest mobile base station.

2) The outside antenna sends the received signal through the coax cable to the installed Repeater.

4) The improved signal goes to the inside antenna through the connection coax cable.

5) The inside antenna send the improved good signal to your mobile phone.

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

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.
