Features of the Nextivity CEL-FI GO RED FirstNet booster

  • Provides cellular coverage in buildings for emergency communications from police, fire, and medical personnel.
  • Works with AT&T’s FirstNet cellular network.
  • NEMA 4 rated to resist water, dust, and dirt.
  • 100 dB maximum gain—up to 30 times more signal gain than competing boosters.

  • Boosts cell signal for multiple users simultaneously.
  • Configure and monitor your booster with the CEL-FI WAVE app for smartphones.

FirstNet is a high-speed, nationwide wireless broadband network being rolled out by AT&T for public safety communications. This new network has dedicated cellular frequencies for law enforcement, firefighters, ambulance, and other first responders and public safety agencies. The CEL-FI GO RED is an in-building cell signal booster that provides maximum gain for the FirstNet network.

The Nextivity CEL-FI GO RED FirstNet cell phone signal booster helps you stay connected and experience fewer dropped calls, undelivered texts, and missed email messages during emergencies and all other times. Boost your signal strength in areas with weak cell service and in buildings with poor inside cell signal.

Who is the Nextivity CEL-FI GO RED FirstNet booster for?

  • Police departments, sheriffs, and other law enforcement agency headquarters and command centers.
  • Fire and emergency medical services stations.
  • Commercial and government buildings with legacy public safety communications systems that need to transition to the FirstNet communications network.
  • Homes of police and fire chiefs and other key personnel who need improved FirstNet reception.
  • Buildings in remote locations with weak cell service (new communities, rural areas, etc.)
  • Buildings made with materials that block outside cell signal (metal, plaster, concrete, UV-coated windows, etc.).

Get more features with the Nextivity WAVE app

The Nextivity WAVE app for smartphones lets you check your CEL-FI GO RED booster’s status and change its settings:

  • Home: An overview of the state of your CEL-FI GO RED booster system, including the outdoor signal quality and strength and quality and indoor antenna separation.
  • Activity: Get detailed technical information on the bands of frequency being amplified and the state of the booster.
  • Advanced: Switch between operators (carriers), enable and disable specific bands and channels of frequency, update your booster’s software, tune your outside directional antenna, and more.

Optional plenum air coax cable upgrade

The CEL-FI GO RED system includes TS‑400 coax cable that connects the amplifier to the inside broadcast antenna. If your building requires fire-rated cableexternal link icon in plenum spaces, please ask us about upgrading to half-inch plenum air coax. Plenum cable fully meets state and federal building codes.

Plenum cable also has nearly half the signal loss per foot of cable compared to TS‑400 coax cable, providing stronger signal from your GO RED booster and a wider indoor coverage area.

(Plenum air cable is available at additional cost. Call Powerful Signal at 435-634-6800 for details.)

* Use either the outside omni antenna or the LPDA antenna, whichever performs best in your circumstances.
 Use the barrel connector to attach lengths of coax cable to achieve optimal cable lengths from the booster to the antennas. Always use the shortest runs of cable necessary to connect the components.

Works with the AT&T FirstNet network

The CEL-FI GO RED FirstNet booster system works only on AT&T’s FirstNet cellular networkexternal link icon, which includes two bands of frequency:

  • AT&T band 12 (uplink 699–716 MHz; downlink 729–746 MHz).
  • FirstNet band 14 (uplink 788–798 MHz; downlink 758–768 MHz).

It does not boost signal for other cellular networks or frequencies.
