Poor signal quality, dropped calls, and reduced data throughput has always been the bane of cellular users. Cel-Fi by Nextivity solves these issues with the easy-to-install DUO+ smart signal booster for Verizon and T-Mobile subscribers. The Cel-Fi DUO+ dramatically improves mobile service issues by eliminating dead zones and dropped calls. It increases voice and data coverage and significantly enhances networking quality for 4G LTE devices. Because the DUO+ is so quick to set up, you’ll immediately experience better LTE signal quality for your phone - a boost from one to five bars is possible. It’s perfect for homes, offices, small businesses, and other indoor spaces.
With a newly patented echo cancellation algorithm, the DUO+ offers the clearest signal levels and data services throughout an indoor coverage area up to 15,000 square feet (1,500 square meters). It’s the highest performing, fully certified, signal booster in its power class. With 100 dB of gain, it reduces your cell phone’s power requirements, extending battery life. The DUO+ does not require the installation of external antennas or cables; nor does it require a sophisticated setup routine by the user. The DUO is self-contained and self-configuring.
The DUO Plus consists of two compact units: a Coverage Unit (CU) and a Network Unit (NU). Simply plug both into a power outlet to instantly improve your cellular signal. The NU senses and captures three LTE bands from the closest cell tower and relays two simultaneously to the CU. The CU then transmits the boosted signal inside the home or business. The units communicate wirelessly over a 5 GHz link. The DUO+ peacefully coexists with other wireless electronics and does not interfere with nearby 2.4 and 5 GHz Wi-Fi, femtocells, and other cellular devices. The total enhanced coverage area equals twice the distance between the NU and the CU. The LED user interface indicates the best span to maximize coverage.
Cel-Fi WAVE is a smartphone app and cloud-based software platform packed with features to help you get the best performance from your Cel-Fi DUO+. The WAVE portal and app includes a dashboard for monitoring signal strength and viewing real-time data and performance metrics. It facilitates registration (if needed), firmware updates, commissioning, installation, optimization, and troubleshooting.

Set up is easy, requiring no tools or special knowledge of cellular networks. First, use your phone to find the best cellular signal. Typically you will get the best signal near a window. Second, place the Network Unit (NU) in the location where you get the best cellular signal. Third, place the Coverage Unit (CU) in the location where you need improved coverage. And finally, use the Cel-Fi WAVE app to finish setup and activation.
