This is an OPEN BOX item. It contains all components but mounting hardware and has been tested but may have slight cosmetic damage (scratches, etc). The manufacturer DOES provide a standard 1-year warranty on open box Cel-Fi units.

Fast Facts about this Product:

  • This repeater kit is best for: AT&T users looking for an easily-installed, powerful signal booster for areas up 13,000 square feet without needing to run cable or mount antennas outside.
  • Coverage area*: up to 13,000 square feet
  • All-in-One Kit? YES
  • Compatibility: This amplifier supports 3G, 4G, LTE and VoLTE for AT&T only. It is NOT compatible or approved for use with ANY other carrier.

Key Features:

  • Cel-Fi doesn't require the installation of external antennas, bulky coaxial cables, handset registration, or a configuration setup by the user. In fact, Cel-Fi intelligently and automatically senses and adapts to its environment-including to changes made by your carrier, or to changes caused by nearby equipment like Wi-Fi, or other Cel-Fi devices.
  • Cel-Fi provides coverage up to 13,000 sq. ft., making it ideal for large homes and offices. Multiple Units of Cel-Fi can be deployed in large offices and will not interfere with coverage strength.
  • Cel-Fi is radically different from traditional repeaters, Cel-Fi is the only intelligent booster that's wireless-in/wireless-out. The Network Unit receives the signal from the mobile network (it requires as little as one bar of signal, or -104 dBm RSCP, and -120 dBm RSRP) and relays it wirelessly to the Coverage Unit that amplifies it for up to 100dB of gain.

*Many factors will influence the actual coverage area you will see from a repeater, including layout/floorplan, construction, and original un-amplified signal strength. Depending on your situation, you may see more or less coverage than the estimates listed here. It is not possible to guarantee coverage area.

Installation notes:

  • There must be at least one bar of usuable signal at the window in which you install the Network Unit. 
  • If the Network Unit and Coverage Unit will be installed too far apart from each other for them to communicate wirelessly, you can use the PRO-X Accessory to connect them via cable instead.

Features & Benefits:

  • Supports WCDMA/HSPA+/LTE(FDD).
  • Up to 100dB of system gain in each band, simultaneously.
  • Wirelessly (5GHzU-NII) linked Network and Coverage Units.
  • Peaceful coexistence with adjacent Wi-Fi (2.4GHz & 5GHz) and femtocell devices.
  • Software-based optimization of integrated antenna coverage pattern which maximizes system gain and provides improved coverage.
  • Automatic Gain Control based on real-time echo-cancellation.
  • Adaptive signal equalization.
  • Nextivity's 3rd-generation (ARES) chipset with 6 core processor
  • Up to four (4) cellular bands supported. Cel-Fi PRO boosts service in the U.S. for AT&T only.
  • Support for E-UTRA bands 2 (1900), 4 (1700/2100), 5 (850) and 12/17 (700).
  • Support for 3GPP Rel.10 features.
  • Seamless integration with the Macro networks. No handset registration, GPS signal requirements, or call handoff problems.
  • Secure and ciphered provisioning.
  • Max EIRP; 10dBm downlink & 24dBm uplink, per band.
  • Network-Safe software prevents uplink system gain from exceeding path loss and eliminates unnecessary rise in base station noise level.
  • Uplink Muting Mode automatically shuts down uplink cellular transmissions when no active user equipment is detected.
  • System shuts down upon Operator’s network command or failure detection.
  • Users can be assured communications are secure, through the encrypted wireless link.
  • Registration, Software Updates and Tech Mode support with the Wave mobile app allowing installer to easily collect network information.
  • Enables the system to communicate with smart phones and the Cel-Fi Wave mobile app for improved functionality.
  • Cel-Fi remains fully functional, even when there are other RF emitters present.
  • Subscriber devices enjoy significant improvements in battery life.

It has definitely helped with reception, but my house is in a reception challenged area with only 1 bar at best. It’s expensive but it does what it is supposed to do. I haven’t seen improved data download speeds, but the upload speeds have improved significantly.
