Cel-Fi DUO+ for Verizon’s 4G LTE and XLTE network is designed to dramatically improve voice and data indoor coverage in up to three bands.


System Features

  • The highest performance, fully certified, signal booster possible in the power class providing a maximum gain of 100dB in each band simultaneously. Approved under FCC Safe Harbor II, Cel-Fi provides up to 30dB more gain than Safe Harbor I.
  • Cel-Fi is engineered differently from traditional repeaters.  Cel-Fi is the only intelligent booster that’s wireless-in/wireless-out.  The Network Unit receives the signal from the Verizon network (it requires as little as one bar of 4G LTE signal or -120dBm RSRP) and relays it wirelessly to the Coverage Unit that amplifies it for up to 100dB of gain.
  • Cel-Fi provides coverage for up to 15,000 sq. ft., making it ideal for offices and enterprise deployments.  Multiple units of Cel-Fi can be deployed in larger footprint settings to support greater coverage areas without concern for mutual interference.Patented 2-unit, 3-hop system eliminates the requirements and installation restrictions associated with cabled connections.
  • Plug and play, simple installation, no external cables, antennas, wires, or drills needed. Clean and compact industrial design.
  • No setup or ongoing maintenance needed.  No reliance on internet, GPS or handset registration with the Cel-Fi system
  • End-to-end cellular communication encryption is maintained and no additional risks of vulnerability.Intuitive LED User Interface (UI) allows quick and easy setup with each unit displaying system information. 
  • Supports coexistence with adjacent Cel-Fi systems.
  • Cel-Fi remains fully functional, even when there are other RF emitters present.Mounting brackets included for wall or ceiling mount options.
  • Users can be assured communications are secure, through the encrypted wireless link.

Wireless Features and Benefits

  • Wirelessly linked Network and Coverage Units (5GHz U-NII band).
  • Peaceful coexistence with adjacent 802.11 (2.4 GHz & 5 GHz), 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 maximizes system gain and provides improved coverage.
  • 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.

Mobile Network Features

  • Up to 3 cellular bands supported; relaying two simultaneously.  Cel-Fi DUO+ boosts service for Verizon 4G LTE and XLTE only.   
  • Supports E-UTRA bands 2(1900), 4(2100/1700), and 13(700).
  • 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 receive noise level.Uplink Muting Mode automatically shuts down uplink cellular transmissions when no active user equipment is detected.
  • Secure and ciphered provisioning for only Verizon’s channels based on network broadcasted PLMN ID. 
  • Full Band Scan feature discovers newly deployed and re-farmed spectrum.
