Cel-Fi GO G51 5G Coverage Solution

The Cel-Fi GO G51 is a self-configuring 5G NR cellular coverage solution engineered to deliver reliable indoor 5G and 4G mobile coverage for commercial, industrial and large residential buildings.

Powered by Nextivity's fourth-generation IntelliBoost® technology, the GO G51 automatically detects and amplifies 5G NR Band n78 (3.5GHz) alongside one LTE band, delivering up to 100dB system gain, 100MHz 5G relay bandwidth, cloud management through the Nextivity WAVE Portal, and carrier-approved operation for authorised mobile networks. It provides enterprise-grade mobile coverage without the complexity or cost of a distributed antenna system (DAS).

Combined with either CEL-FI Omni Dome Antenna(s) for ceiling mounting or CEL-FI Wideband Panel Antenna(s) for wall mounting, the CEL-FI GO G51 and CEL-FI Wideband Directional Antenna is the perfect in-building, remote, and IoT solution. Additional server antennas are available for venues with more floors or dense interior wall, while the higher gain LPDA-R antenna is available for sites with weak outdoor signals

What is the Cel-Fi GO G51?

The GO G51 is a next-generation indoor cellular coverage solution designed to improve 5G NR (Band n78) and 4G LTE coverage inside commercial buildings, industrial facilities and large homes.

How is the GO G51 different from the GO G41?

The GO G41 boosts LTE bands (and 5G DSS where available), while the GO G51 is specifically designed for mid-band 5G NR (3.5GHz / Band n78). It can simultaneously relay 5G NR plus one LTE band, delivering significantly better performance for modern 5G deployments.

Does it support true 5G?

Yes. The GO G51 is designed specifically for 5G NR (New Radio), including Band n78, which is the primary mid-band 5G frequency used by many mobile operators for high-speed services. It also supports 4G LTE alongside 5G.

Is the GO G51 self-configuring?

Yes. The system automatically detects and optimises supported networks, reducing installation complexity while maintaining optimal performance. Advanced configuration and monitoring are available through the Nextivity WAVE App and WAVE Portal.

Can the GO G51 be monitored remotely?

Yes. The built-in Ethernet and cloud connectivity allow installers and administrators to monitor system health, signal quality and performance remotely using the Nextivity WAVE Portal.

Who is the GO G51 designed for?

The GO G51 is ideal for businesses and organisations requiring reliable indoor 5G connectivity, including offices, warehouses, hospitals, schools, shopping centres, government facilities and industrial sites where outdoor 5G signals struggle to penetrate the building.
