Anterix: ‘Terrific’ results from NTN testing with Lynk Global

Anterix has successfully concluded initial testing of Sat2Phone non-terrestrial network technology in collaboration with satellite direct-to-device provider Lynk Global. The trial focused on the application of 900 MHz licensed spectrum to bridge connectivity gaps for critical infrastructure, specifically within the utility and enterprise sectors. By leveraging low-earth orbit satellites, the companies aim to provide seamless coverage for devices that operate beyond the reach of traditional terrestrial cellular networks.

The demonstration utilised standard 3GPP-compliant hardware to establish a direct link between satellites and terrestrial devices without the requirement for specialised terrestrial equipment. This capability allows utility companies to monitor remote assets and maintain communications in geographically isolated areas where installing physical towers is cost-prohibitive or physically impossible. Anterix noted that the performance metrics from these tests exceeded initial expectations regarding signal reliability and data throughput.

For the utility sector, the integration of non-terrestrial networks provides a resilient backup for grid management and emergency response operations. The ability to switch between terrestrial private LTE networks and space-based platforms ensures that crucial telemetry data continues to flow even during natural disasters or network outages. Anterix holds a significant portfolio of 900 MHz spectrum across the United States, which is well-suited for penetrating obstacles and covering long distances.

The collaboration with Lynk Global highlights a shift in the satellite market from consumer-focused messaging services to industrial-grade connectivity. While much of the recent satellite-to-cell development has targeted smartphone users for emergency SOS features, this project focuses on machine-to-machine communications and the Internet of Things. Ensuring that smart meters and grid sensors remain connected globally is a primary goal for the ongoing technical partnership between the two firms.

Looking ahead, Anterix intends to refine the integration of satellite roaming into its existing private wireless ecosystem for utility customers. Further testing will explore the scalability of the service and the impact of atmospheric conditions on 900 MHz satellite transmissions. As the satellite constellation expands, the partners expect to move toward a commercially viable service that offers near-continuous coverage for critical infrastructure monitoring across the North American market.
