Cel-Fi DUO+ 3G/4G/LTE Smart Signal Booster for T-Mobile


The Nextivity Cel-Fi DUO+ is the next generation of intelligent repeater kits for home and business users looking to boost their cellular network performance. This LTE signal booster is for T-Mobile network users and works with LTE bands 2, 4 and 12. Each all-in-one cell booster kit can provide high-gain coverage improvements for up to 15,000 square feet.

The T-Mobile Cel-Fi signal booster is completely wireless both in and out. Furthermore, it automatically sets itself up and adjusts itself based on signal strength. As long as there is at least one bar of signal, the Network Unit will pick it up and relay the signal to the Coverage Unit via an encrypted wireless link. A software-based coverage pattern analysis is used to optimize gain, and with a peak gain of 100 dBi, it can turn even a weak signal into a robust connection.

A Cel-Fi DUO+ system is designed so it can function around other RF signal emitters or Wi-Fi devices without interference to the booster technology. In addition to self-adjustments for signal, it will also adapt to T-Mobile carrier changes or new equipment installations. Using a Smart T-Mobile Signal Booster will vastly improve the coverage area even in larger homes and offices, and you won’t need to add antennas or coaxial cables in order for your phones or other devices to benefit from the boosted signal.

Installation notes:

  • There must be at least one bar of usable signal at the window in which you install the Unit.

Features & Benefits:

  • Wirelessly linked Network and Coverage Units (5GHz U-NII band).
  • coexistence with adjacent 802.11( 2.4GHz&5GHz), and femtocell devices.
  • Max EIRP: 10 dBm downlink per 5 MHz and up to 22 dBm uplink, per band.
  • Software-based optimization of integrated antenna coverage pattern which increases system gain and provides improved
  • Automatic Gain Control (AGC) based on real-time echo-cancellation.
  • Seamless call handovers between Cel-Fi systems and the macro network.
  • Subscriber devices enjoy improvements in battery life.
  • Bluetooth communications between a mobile handset and Cel-Fi via our Cel-Fi WAVE Mobile App provides software update
    capability and advanced information for technical support.
  • Adaptive signal equalization.
  • Includes Nextivity's 3rd-generation (ARES) chipset with 6 core processor.
  • Up to 3 cellular bands supported; relaying two simultaneously
  • Supports E-UTRA bands 2, 4, and 12 for T-Mobile
  • Support for 3GPP Rel. 10 features.
  • Network-Safe software prevents uplink system gain from exceeding path loss between Network Unit and closest tower,
    thus eliminating unnecessary rise in base station noise level.
  • Uplink Muting Mode automatically shuts down uplink cellular transmissions when no active user equipment is detected.
  • Secure and ciphered provisioning for only T-Mobile’s channels based on network broadcasted PLMN ID.
  • Full Band Scan feature discovers newly deployed and re-farmed spectrum
