Product Description

Cel-Fi DUO Signal Booster for T-Mobile 3G, 4G & 4G LTE! Are you tired of dropped calls, poor voice quality, and dead zones when using your phone in your home or business? Are you in an area that commonly experiences low coverage, where youÕre lucky to get two or three bars on your phone at a time? For T-Mobile customers, the solution is here. Subscribers are now able to boost their network signals with the launch of the Cel-Fi DUO.

All you need is one bar, and this smart signal booster designed for use on 3G, 4G LTE (including VoLTE) and UMTS networks, will allow you to boost your signal to five bars with ease. Dulled indoor network experiences that result from network signals hitting walls will now be a thing of the past, with the FCC approved 100dB boost providing up to 13,000 ft. of coverage with every unit.

The Cel-Fi DUO is small and compact, packed with features, and requires minimal setup. It is a plug and play booster - all you need to do is place the CelFi Tmobile window unit and them the coverage unit where you need the most coverage. Both will configure themselves and communicate as needed. There is no extraneous cabling or antennae. The DUO also offers boosting for UMTS/WCDMA voice signals on the T-Mobile network, and uses patented echo-cancellation algorithms for stronger, clearer signals. Therefore, dual band boosting on frequencies 2 (1900MHz) and 4 (1700/2100MHz) can occur simultaneously.

The Cel-Fi DUO is made up of two separate units. The window unit captures signals from the closest T-Mobile cell tower within range and sends it inside the building, where the coverage unit then takes over by providing boosted signals in the surrounding home or business.

The Cel-Fi DUO comes with one (1) Network Unit, one (1) Coverage Unit, two (2) Power Supplies, two (2) Mounting Brackets and a Quick Start Guide.
