How It Works
1
The powerful antenna reaches out to access a voice and 3G, 4G, and LTE data signal, and delivers it to the booster
2
The booster receives the signal, amplifies it, and serves as a relay between your phone and the nearest cell tower.
3
Your devices get increased cell reception, and calls and data are fed through the booster back to the network.

Normal Cell Coverage
Dropped calls and slow data are generally caused by three things: distance from a cell tower, building materials in your home or office, or obstruction from tall objects such as trees, topography, and buildings.
Signal Coverage with our booster
Signal boosters increase cell signal by collecting signals with a powerful antenna, delivering those signals to the booster, amplifying the cell signals so your devices receive them, and delivering your device's boosted signals back to the cell tower.Installation
