Cel-Fi is the only Smart Signal Booster approved and authorized by AT&T Wireless and T-Mobile

Cel-Fi Smart Signal Booster is authorized by one hundred and thirty nine carriers worldwide in seventy countries at the time of this survey, for use on their mobile networks. What is Cel-Fi? It is currently the only Smart Signal Booster approved and authorized by AT&T Wireless and T-Mobile USA for use on their networks. Unlike most analog boosters, it boosts mobile coverage within large homes and office buildings of upto 13,000 square feet. It eliminates dropped calls and static during phone conversations. Like us, it is obsessed with finding coverage: Unlike previous generation boosters, it is powered by an intelligent processor core that is designed to detect interference and adjust the coverage area accordingly, so as to provide the largest possible coverage area. Like traditional boosters, it is composed of two units that connect wirelessly: Window unit brings wireless-in and pushes wireless-out to the coverage unit to boost signal from only one bar to five bars (it needs just one bar of 3G or 4G coverage) - Minus the installation hassles!

However, unlike traditional legacy boosters, it provides high capacity coverage: 60 simultaneous users, 4 to 20 times higher download speed. Provides maximum gain of 100dB or 1000 times more gain than the industry average. Its powerful internal antenna gain is five times more powerful than the best smartphone available! Hands down, it is the most sophisticated and advanced booster in the market. Furthermore, it is a breeze to install - No need for outdoor antenna, cables and other installation. Just plug Cel-Fi in and it works! With insanely simple installation in five minutes this plug and play Cel-Fi configures itself automatically. It is the only carrier-specific booster available in the market today and the one and only booster approved by the FCC in the “provider specific” category. It offers 100dB, or 1,000 times more gain than the most powerful wideband analog booster. It uses a next generation all-digital advanced technology with ARES, the Cel-Fi processor with six-cores RISC baseband processor, which is 5 times more powerful than previous generation digital signal processors.
