How It Works
SureCall’s EZ 4G is a high-quality bidirectional signal booster that enhances cellular signals to areas that are
prone to weak cellular coverage.
How it works
1. An antenna built into the back of the booster communicates with the cell tower while it sits in your window.
2. The booster amplies the existing cell signal and sends it to the tabletop antenna.
3. The tabletop antenna rebroadcasts the signal indoors to all mobile devices within range.
4. The booster amplies outgoing cell signal back to the tower.
