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.
