The Cel-Fi Duo+ Smart Signal Booster repeater kit can be used by home and enterprise consumers to improve indoor cellular signal for better Verizon voice and data performance. This model works with Verizon’s U.S. network and is compatible with their 4G LTE and XLTE frequency bands, boosting all Verizon devices within range. Cel-Fi provides coverage for up to 15,000 square feet, making it perfect for large homes and offices.

Cel-Fi boosters are radically different from traditional repeaters, as they are the only intelligent booster that's wireless-in/wireless-out. The Network Unit receives the signal from the mobile network (it requires as little as one bar of signal) and relays it wirelessly to the Coverage Unit that amplifies it for up to 100dB of gain. The wireless link is encrypted as well to maintain secure communication. It supports as many as three cellular bands and can still function in the presence of other RF signal emitters or Wi-Fi devices.

Cel-Fi is easy to set up and doesn't require the installation of external antennas or bulky coaxial cables. It also doesn’t require handset registration or a configuration setup by the user. In fact, Cel-Fi intelligently and automatically senses and adapts to its environment, including to changes made by your carrier or to changes caused by nearby equipment like Wi-Fi or other Cel-Fi devices. Gain is optimized using a software-based coverage pattern for better performance. This Verizon booster simplifies LTE signal boosting and can quickly add thousands of square feet to a coverage area!

Compatible Carriers (4G LTE & 3G): T-Mobile and Verizon

Amplifier Features:

  • Coverage area: up to 15,000 square feet

  • Compatibility: This amplifier supports 4G LTE, XLTE, and VoLTE (HD Voice) for Verizon and T-Mobile. It is NOT compatible or approved for use with ANY other carrier.

  • Installation: Cel-Fi doesn't require the installation of outdoor antennas, bulky coaxial cables, handset registration, or a configuration setup by the user. In fact, Cel-Fi intelligently and automatically senses and adapts to its environment-including the changes made by your carrier, or the changes caused by nearby equipment like Wi-Fi, or other Cel-Fi devices. Multiple Units of Cel-Fi can be deployed in large offices and will not interfere with coverage strength.
