How Does It Work?:

The signal boosters outside antenna receives the weak 3G data signal, from the mobile network provider ( and then delivers it to the signal repeater.

The signal booster then amplifies the signal and acts as a relay between the mobile network and your mobile device.

The signal booster then transmits the signal through the indoor antenna so your devices get increased cell reception. Calls and data are routed back through the signal repeater to the mobile network provider.
