How a Cell Phone Booster System Works
The outside antenna receives voice and data signal from the cell tower.
The signal booster amplifies the outside signal and sends it to one or more inside antennas.
The inside antennas broadcast the amplified signal to needed areas, eliminating dead spots.
Our cellular boosters work on all networks and with all carriers.
5-band cell phone boosters amplify 5G, 4G LTE, and 3G carrier network signals.
