Description

Cel-Fi GO G51 Smart Signal Repeater – Commercial & Enterprise Kit

(Premium RFI Equipment)

The Cel-Fi GO G51 is an enterprise-grade, fully ACMA-approved and carrier-endorsed smart signal repeater engineered for large buildings, commercial spaces, and high-demand environments where mobile connectivity is business-critical. The G51 excels in mid-band 5G (3.5 GHz) environments, delivering superior performance when strong 5G signal exists outdoors but struggles to penetrate indoors.

Supporting 5G (3.5 GHz) and 4G across Telstra, Optus and Vodafone, the G51 is built to provide high-capacity, high-speed mobile coverage for dense or expansive commercial environments that require robust throughput, enhanced reliability, and multi-user performance.

All G51 kits come equipped with premium RFI donor antennas, internal distribution antennas, and ultra-low-loss RFI cabling. These professional-grade components ensure maximum donor signal capture; particularly for mid-band 5G, and efficient distribution across larger indoor spaces.

Thanks to its increased output power, the Cel-Fi GO G51 platform can be architected to support approximately 3,000 m² of indoor coverage, depending on building layout, structure, and signal conditions. It also supports two simultaneous channel bands, improving network performance across high-traffic areas and commercial-grade applications.


Best For: Large Buildings, Commercial Environments & Mid-Band 5G Applications

The Cel-Fi G51 is the recommended model when:

  • You have strong or reliable mid-band 5G (3.5 GHz) outdoors
  • You require coverage across large, dense, or multi-room commercial floorspace
  • Your building has poor indoor penetration despite strong external signal
  • You need enterprise-level capacity, reliability, and multi-user performance
  • You require a fully legal, ACMA-approved repeater for commercial deployment

This makes the G51 ideal for:

  • Commercial buildings & corporate offices
  • Warehouses, logistics hubs & industrial facilities
  • Shopping centres, retail complexes & multi-tenant spaces
  • Hospitals, medical facilities & educational campuses
  • Government, defence, emergency services & high-demand environments
  • Hospitality venues, stadiums, clubs & large public spaces

If your location benefits from strong outdoor mid-band 5G, the G51 paired with premium RFI antennas delivers exceptional indoor performance designed for commercial scale.
