Working principle

1. Receives Signal
The powerful antenna reaches out to access a good signal, and delivers it to the booster.

2. Boosts Signal
The booster receives the signal, amplifies it, and serves as a relay between your phone and the nearest cell tower.

3. Broadcasts Signal
Your devices get increased cell reception, and calls and data are fed through the booster back to the network.
