Cel-Fi DUO+ Indoor Smart Signal Booster for 4G LTE Networks, Choice of Verizon or T-Mobile → Cel-Fi DUO Plus Smart Signal Booster for Verizon or T-Mobile 4G LTE Networks

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 APP

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.

Dashboard: Glance-able view to the state of your Cel-Fi environment, including the Boost Strength indicator. It features: Settings: Change the default network operator, select the booster technology (3G, 4G), setup an external antenna, configure the antenna position, and more. Advanced Mode: Get real-time data and performance metrics for troubleshooting devices. Booster Updates: Keep your Cel-Fi Booster up-to-date as new software versions become available.
