How does it work?
Cel-Fi mobile signal boosters improve signal between a mobile phone and a mobile network tower, allowing you to have clear voice conversations and a stable data connection when you are inside. An external donor antenna collects the best mobile signal from outside and transmits it to a mobile signal booster unit. The unit strengthens the signal and rebroadcasts it inside the building via internal donor antennas.
