How Does It Work?

With the SureCall EZ 4G Five-Band Home Cellular Signal Booster, you place a large round antenna by the window of the room where you have good reception and want to improve reception farther away. The window antenna receives the signals broadcasted by all of the carriers from all of the cell phone towers in the area and then amplifies them by up to 72 decibels. The amplified signals are transmitted in the room by a desktop unit that must be positioned at least 30 feet away from the window receiver where there's weak signal you want to improve. AT&T smart phones, tablets, mobile hotspots, and all other cellular devices then receive the signals from their specific carriers.

Summary:

1. An antenna built into the back of the booster communicates with the cell tower while it sits in your window (either booster attached directly to window glass using the provided adhesive, or placed on the stand provided to set the booster on the window sill).
2. The booster amplifies the existing cell signal and sends it to the tabletop antenna.
3. The table-top antenna rebroadcasts the signal indoors to all ATT and all other service provider mobile devices within range.
4. The booster amplifies outgoing cell signal back to the tower.
