450 MHz Band: The Strategic Spectrum Powering Resilient Connectivity for Critical Infrastructure

Why 450 MHz Band is Gaining Global Adoption

The 450 MHz Band is becoming the go-to solution for companies that require reliable, long-range and secure communication. This is especially true for those operating where conventional cellular coverage falls short.

The 450 MHz band is no longer niche—it’s a fast-growing global trend.

Europe: Germany, Sweden, and Finland are actively licensing 450 MHz for energy and public safety. In Germany, 450connect is deploying a national LTE450 network for critical infrastructure.

Asia-Pacific: Several countries are enabling 450 MHz for private LTE in utilities and smart city deployments, with growing regulatory support.

Latin America & Africa: 450 MHz is seen as a practical spectrum for closing the connectivity gap in underserved areas, including agricultural and industrial zones.

United States: While the 450 MHz band is not widely available in the U.S., private LTE and 5G networks are gaining momentum through other licensed and shared spectrum options. However, Anterix, which operates in the 900 MHz band is leading the way by enabling private LTE networks for utilities and the critical infrastructure industry. It can be said that at the same time, CBRS (Citizens Broadband Radio Service) which functions in the 3.5 GHz band is becoming more popular across campuses, ports, logistics, and municipalities. These trends align with the same strategic priorities seen in 450 MHz deployments globally: ensuring dedicated spectrum, establishing secure private networks, and providing reliable communications for mission-critical operations.

Exceptional Coverage and Propagation

450 MHz band provides unmatched range and deep indoor/underground penetration. This makes it an ideal solution for rural and remote sites, utility substations and pipelines, and critical infrastructure, all of whom work in challenging environments. The reason that it’s becoming adopted so quickly is because fewer base stations are needed, meaning it’s cost-effective and offers wide-area coverage.

Designed for Mission-Critical Applications

This spectrum is not about high-speed consumer data—it’s about availability, determinism, and control. Ideal for SCADA systems, smart grids and AMI (Advanced Metering Infrastructure), and industrial IoT and telemetry.

The Ecosystem is Evolving

The 450 MHZ band’s growing success is driving a significant expansion of the supporting technology ecosystem. As a result, an increasing number of device manufacturers are incorporating 450 MHz support into industrial-grade products. These include routers, IoT gateways, and smart infrastructure solutions. Simultaneously, the industrial module and radio infrastructure markets are aligned with the band’s requirements, enabling them to provide solutions compatible with LTE and even 5G. This expanding ecosystem streamlines deployment, reduces integration costs, and increases availability of field-proven solutions for critical infrastructure sectors.
