The Cel-Fi GO G41 FN booster provides reliable cellular coverage in buildings for first responders on the FirstNet network.

The most powerful FirstNet coverage solution in its class, GO G41 FN features the latest 4th generation Nextivity proprietary IntelliBoost technology to deliver channelized signal boosting and industry-leading signal gain up to 100 dB that keeps police officers, fire safety personnel, and other emergency response teams connected.

Key Features

The CEL-FI GO G41 FN is the FirstNet-only version of the industry-leading CEL-FI GO G41.

The GO G41 FN is different from the majority of other boosters we sell in 3 ways:

  • The GO G41 FN is a FirstNet-only device and will only amplify signal for FirstNet.
  • The GO G41 FN offers up to 100 dB gain. Unlike most other boosters, the CEL-FI GO G41 is not restricted to 70 dB gain by the FCC. It offers about 30 dB more signal amplification, which means the G41 FN covers the same area as about 11 competing boosters combined.
  • The G41 FN is ready for 5G. A firmware update in 2024 will add full 5G NR capabilities on all supported frequency bands.

What is FirstNet?

Not all areas and buildings have good cellular signal, due to building materials or remote locations. Remote Communication Kits are now a standard tool for emergency service personnel.

FirstNet is a high-speed, nationwide wireless broadband network with dedicated bands for public safety agencies and first responders.

Where buildings use FirstNet, the Cel-Fi GO G41 FN can work alongside existing legacy equipment, to ensure FirstNet service is available at the point of transition.

WAVE App (for IOS and Android)

Installing the GO G41 FN is easy thanks to CEL-FI's WAVE app, which allows for easy setup and advanced optimization on the device. The WAVE app is available for iPhone and Android and allows users to connect to their CEL-FI device via Bluetooth.

Within the app, users can view detailed diagnostic information including measures of signal strength, amplifier gain levels, and signal quality. Waveform's detailed installation manual also leads the user step-by-step through the setup process. For any additional assistance, our expert technical support team is always available.

Coverage Area

The coverage area of any signal booster system depends on two factors:

  1. The outdoor signal strength
  2. How many indoor antennas you use

At peak performance, the CEL-FI GO G41 FN can cover up to 15,000 sq ft in an open area. In a typical home or office environment, the same kit will cover up to 10,000 sq ft.

In general, the more antennas you have, the larger the coverage area of the system. Signal passes through cables much more easily than through walls and even through the air, so adding more antennas helps expand the coverage of your booster.

As a rule of thumb, we recommend installing one antenna for every 1000 sq ft to 1500 sq ft of space in a typical home or office environment that has internal walls. If the environment is more open, such as in a warehouse or open office floor, you can install one antenna for every 1,500 to 3,000 sq ft.

Coverage areas of any booster will always vary from building to building. If you'd like help understanding the coverage you should expect from the G41, please reach out to our team of signal specialists.


Cel-Fi warranties all of their amplifiers, antennas, and RF components for 2 years against any workmanship or material defects.
