Across Europe, the 450 MHz spectrum is attracting renewed momentum particularly among utilities preparing their networks for the next decade of modernization. Once viewed as a niche band, 450 MHz is now being recognized as a highly resilient spectrum uniquely suited to critical infrastructure. And as operators plan long-term deployments for smart metering, grid automation and distributed energy resources (DER), interest in dependable, future-proof connectivity is accelerating.
Why 450 MHz is Back in the Spotlight
Several European countries have specifically allocated 450 MHz spectrum for critical infrastructure, with licenses held by utilities or dedicated operators serving the energy sector. This allows utilities to deploy connectivity designed intentionally for their operational requirements, limiting exposure to public network congestion or commercial priorities.
The spectrum’s characteristics make it particularly valuable for energy infrastructure:
- Low frequency of 450 MHz enables extended range and deep building penetration, ideal for meter rooms, basements and rural substations.
- Stable performance across dense cities, remote agricultural areas and industrial regions.
- Compatibility with LTE-M/Cat-M and NB-IoT, the low-power technologies widely used in smart metering and grid gateways.
Live 450 MHz networks are already in place in several European countries including the Netherlands, Germany, Austria, and Poland — demonstrating both ecosystem maturity and market confidence.
Market Momentum: A Shift Driven by Utility Realities
Smart grid deployments are long-term undertakings. The equipment installed today will remain in the field for 10 to 15-plus years and communication networks must remain stable over the full lifecycle.
Recent tenders reflect this reality. Utilities are moving beyond limited pilots toward large-scale, strategic deployments. Smart metering gateways, grid monitoring nodes and DER controllers are increasingly being planned with 450 MHz as their foundational layer.
What Utilities Need Most: Reliability, Longevity and Trust
Beyond choosing components, utilities are selecting long-term strategic supply partners who can provide:
- Long-term product availability and lifecycle support
- Ongoing hardware, firmware, network, and platform support
- Proven ability to scale deployments over time
In an environment where data sovereignty, supply-chain resilience and operational independence matter more than ever, decision-makers are increasingly looking for vendors with established presence and industry’s expertise.
Introducing the HL7845: Purpose-Built for Europe’s Energy Networks
The Semtech® HL7845 is a 450 MHz LTE-M/NB-IoT module designed specifically with long-lifecycle utility deployments in mind.
Key advantages of the HL7845 include:
- Support for Europe’s 450 MHz (31, 72) and 410 MHz (87, 88) bands used in private utility networks
- Support for widely deployed public LTE bands. Enabling flexible hybrid or roaming architectures
- Ultra-low power performance, enabling years-long operation in the field without intervention
- A CF3 form factor shared across the HL7xx LPWA module family, making it easier for OEMs to scale or migrate without redesigning hardware
Because it builds on an already widely deployed architecture used in millions of smart meters today, the HL7845 offers a familiar, proven path forward without forcing utilities to change what already works.
Looking Ahead: 450 MHz as the Backbone of Europe’s Energy Transition
As utilities modernize their networks, they need communications technologies that will remain reliable through technology shifts, regulatory change and evolving operational priorities. The 450 MHz band offers a strong foundation: its coverage characteristics, performance in challenging environments and proven suitability for energy applications make it a natural fit for long-term infrastructure deployments.
Semtech has a long track record supporting smart metering and grid connectivity across Europe, with stable product roadmaps, firmware evolution plans and local technical support. Our commitment is to remain a dependable partner from initial deployment through full operational life.
