This cellspot signal booster is similar to branded Tmobile Wireless Router Personal Cellspot WiFi model. This Cel-Fi branded Cell Spot for T Mobile does not require broadband home Internet service for it to work. Nextivity Cel-Fi DUO+ Smart Signal Booster for T-Mobile.

Are you tired of dropped calls, poor voice quality, and dead zones when using your T-Mobile phone in your home or business? Are you in an area that commonly experiences low coverage, where you're lucky to get two or three bars on your phone at a time? For T-Mobile customers, the solution is here: T-mobile DUO+ signal booster. Subscribers are now able to boost their network signals with the launch of the Cel-Fi DUO Plus.

All you need is one bar, and this celfi tmobile smart signal booster designed for use on 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. This cel fi t mobile kit 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 DUOPlus also offers boosting for UMTS/WCDMA voice signals on the T-Mobile network, and uses patented echo-cancellation algorithms for stronger, clearer signals. Therefore, triple band boosting on frequencies 2 (1900MHz), 4 (1700/2100MHz), and band 12 can occur simultaneously.

The Cel-Fi DUO Plus 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. Automatic channel selection feature on the 5 GHz link makes sure there’s no interference with Wi-Fi routers, cordless phones, baby monitors etc.

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

Note: For any signal booster to help, outside signal strength must be at least -110 dB or there must be a clear line of sight to a cell tower that is within twenty miles. Please check outside signal level in decibels before ordering. Square footage stated in signal booster listings is based on good signal outside. If it is any weaker, the boosted sq. ft. area will be considerably lower, accordingly.

If it is too weak, submit request for cell coverage solution assessment. Upon receipt of questionnaire, we will perform residential or business site survey. This will help us determine the system that is needed to improve cell coverage. Then, we will create system design using that system such as femtocell, active or hybrid distributed antenna system (DAS), or other carrier feed signal enhancing method available that will work at your signal-challenged location. Finally, we will schedule for installation after equipment and installation service quote has been approved by you, or your company.

Please note: Most home / office / building cell signal booster kits only include bracket to mount exterior antenna on outside wall, edge of roof, or existing pipe up to 2 inches in diameter. Mounting pole not included with most kits, unless stated specifically that it is included for free. Therefore, a mounting post must be purchased separately if you will require it to mount exterior antenna.
