The Cel-Fi GO G41 FN and the Cel-Fi GO X G32 (now simply GO G32) stand out as two of the company’s most advanced solutions. Both models harness Nextivity’s proprietary IntelliBoost technology, but each is tailored for unique needs. The GO G41 FN is purpose-built for FirstNet public safety, while the GO G32 offers unmatched flexibility for both stationary and mobile use. As reliable connectivity becomes essential for businesses, emergency responders, and rural users, understanding the differences between these two models is crucial. This guide explores their technology, performance, installation, and best-fit scenarios, helping you make a confident decision for your connectivity needs.

What Sets Nextivity’s Technology Apart?

Nextivity’s signal boosters are renowned for their advanced engineering and reliability. Both the GO G41 FN and GO G32 utilize IntelliBoost, a technology that intelligently amplifies weak cellular signals without causing interference. The GO G41 FN, as the latest generation, is equipped with six front-end receivers, enabling it to process and amplify signals from AT&T’s FirstNet Band 14 alongside standard commercial bands. This makes it a top choice for emergency services that require prioritized, uninterrupted network access.

The GO G32, on the other hand, is designed for versatility. Its dual-mode system allows users to switch between stationary and mobile operation, adapting gain levels for each scenario. In stationary mode, it delivers up to 100 dB of gain, while mobile mode offers 65 dB in North America. This adaptability makes the GO G32 suitable for a wide range of environments, from office buildings to vehicles.

Both models are engineered to be “unconditionally network safe.” This means they amplify signals without causing interference to carrier networks or other wireless devices, a feature that sets them apart from many generic boosters. Their clean amplification ensures compliance with carrier and regulatory standards, providing peace of mind for users in sensitive environments.

Key Features of IntelliBoost Signal Processing

IntelliBoost is the heart of both the GO G41 FN and GO G32, delivering intelligent, real-time signal amplification.
