Cel-Fi Advanced Technology:
Cel-Fi is a new generation of all-digital Signal Boosters and the only booster approved by the FCC for 100dB gain. Our Cel-Fi boosters are designed using the most advanced technology and are powered by two custom-made 6-core processors allowing for 1000 times more gain than traditional boosters and provides coverage to 13,000 sq. ft. The only ‘Smart Booster’ of its kind, Cel-Fi decodes the setup channel, adapts to future network changes on its own and even makes the carrier network more efficient.
How does Cel-Fi work:
The Cel-Fi Network Unit captures the weak signal that reaches the building, improves it and retransmits the signal indoors via the Coverage Unit. This allows your AT&T and T-Mobile clients to experience a strong cellular connection with no signal interference-eliminating dropped calls and in-building dead zones. Cel-Fi is the only cellular booster authorized for use on AT&T and T-Mobile networks.
Cel-Fi boosts your signal strength indoors for 3G, 4G LTE Voice and Data without the need for external antennas or cables. We made Cel-Fi worry-free by making it insanely simple to install, providing you with a true plug and play booster that is an ideal solution for your clients office or home. Multiple units of Cel-Fi can be installed for larger projects with no interference issues from booster to booster or the carrier’s network. With our 100dB gain, clients who are experiencing weak network coverage will go from 1 bar to 5 with wide ranging coverage guaranteed.
