How does it work?

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

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

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