LTE450 Network Coverage: Germany, Austria and Europe

LTE450 is not a single global network. It is a technology standard – LTE running in the 450 MHz frequency band – that individual national operators license and build independently. Coverage depends entirely on what has been deployed in your country and, within that country, what has been built in your specific region.

This page covers the current state of LTE450 network deployment in Germany and Austria, the two most developed markets, along with a summary of activity elsewhere in Europe. It is updated periodically as rollout progresses.

For technical background on why 450 MHz propagates differently from standard mobile frequencies, see the LTE450 network overview. For hardware that operates on these networks, see the vendors page.

Why 450 MHz Coverage Is Different

Before looking at specific networks, it helps to understand why the 450 MHz band produces coverage that looks fundamentally different on a map.

Standard commercial LTE uses frequencies from around 700 MHz up to 2.6 GHz and above. Higher frequencies carry more data but attenuate quickly – the signal weakens with distance and struggles with obstacles. A nationwide commercial LTE network requires tens of thousands of base stations to maintain coverage.

At 450 MHz the physics work in the opposite direction. The longer wavelength travels further and penetrates obstacles – walls, terrain, building fabric – more effectively. Comparative data from the 450 MHz Alliance puts it plainly: at 410 MHz, 100% of devices within the coverage footprint maintain a connection. At 740 MHz that drops to 91.3%. At 2.35 GHz it falls to 58.7%. At 3.85 GHz, only 45.6%.

The practical result is that a 450 MHz network achieves the same geographic footprint as a commercial LTE network with a fraction of the base stations – a few thousand rather than tens of thousands for a country the size of Germany. That matters for build speed, for economics, and for the resilience of the network: fewer sites to keep on emergency power during a blackout.

The same physics that make 450 MHz efficient for rural coverage also make it effective for penetrating basements, shafts, underground meter installations, and enclosed substations – exactly where critical infrastructure assets tend to be.

Germany: 450connect

Background

450connect GmbH is a joint venture backed by the German energy and water sector. In March 2021, the Federal Network Agency (Bundesnetzagentur) awarded it the 450 MHz spectrum licence for Germany, valid to 2040. Nokia was contracted as the network infrastructure partner on a deal covering supply, deployment, and 20-year lifecycle management of the network technology.

The Versorger-Allianz 450 – an association of more than 200 German energy and water utilities – is a co-owner of 450connect. This structure means the network is governed by the utilities that depend on it, not by a commercial mobile operator with competing commercial interests.

450connect services cover voice communication, M2M data products, and a customer portal for SIM and service management. The network is described as geo-redundant and designed to remain operational during extended power failure scenarios, with emergency power supplies at base station sites and flood-resilient siting decisions built into network planning.

Current Coverage State

Coverage has expanded rapidly. In Q1 2025 the network covered approximately 30% of Germany geographically. By December 2025 that figure had passed 90%. Full nationwide coverage is targeted for 2026.

More than 10,000 transformer stations across Germany are already connected to the network. Smart grid applications, emergency notification systems for substations, decentralised generation facilities, and gas and water network installations are all in live operation on the network.

The network build has relied partly on co-location with existing infrastructure. Energy utilities holding membership of the Versorger-Allianz 450 have contributed mast locations within their own supply areas – a practical approach that accelerated rollout in regions where utility companies already had elevated structures available.

Checking Coverage at a Specific Location

Coverage checking for the 450connect network requires direct engagement with 450connect. There is no publicly accessible coverage map – the network is not a public service and the coverage verification process is part of the operator onboarding workflow.

To check whether a site falls within the current or planned coverage footprint, contact 450connect directly via 450connect.de. Existing 450connect customers can access coverage and network status information through the customer portal.

For sites not yet within coverage, see the fallback section below.

Access and SIM Provisioning

Access to the 450connect network is restricted to operators of critical infrastructure in Germany. SIM cards are distributed by 450connect directly – they are not available through hardware manufacturers or third-party resellers.

The procurement process involves a framework agreement with 450connect, followed by onboarding into the customer portal for SIM and service management. The portal provides control over SIM card status, service usage monitoring (SLA), and network information.

Austria: ArgoNET

Background

ArgoNET GmbH holds all 450 MHz spectrum licences in Austria. The company was founded in 2013 and is headquartered in Gmunden, Upper Austria. It is the sole licensed 450 MHz operator in Austria for critical infrastructure applications.

The company’s ownership reflects a similar utility-backed structure to 450connect in Germany. Energie Steiermark (the regional energy provider for Styria) holds a significant stake, as does Energie AG Oberösterreich Telekom. The network’s roots are in Styria and Upper Austria, where it was initially deployed in partnership with these utility investors.

ArgoNET’s stated focus is high-quality wireless networks for critical data transmission in energy, transport, health, and public infrastructure sectors. As well as 450 MHz, ArgoNET operates networks using 3G, 4G, and 5G spectrum.

Current Coverage State

ArgoNET has coverage across significant parts of Austria, with strongest deployment in Styria and Upper Austria reflecting the early utility partnerships there. National footprint expansion is the current development phase – the company has publicly stated its intent to extend 450 MHz coverage to a nationwide footprint and connect additional user groups and applications.

ArgoNET has also been involved in specific urban IoT applications, including a Vienna city lighting control pilot using 450 MHz connectivity for smart streetlight management.

Precise coverage data for specific Austrian locations requires direct contact with ArgoNET at argonet.at. SIM cards for the Austrian 450 MHz network are distributed by ArgoNET to qualifying critical infrastructure operators.

Wider Europe

Denmark: Cibicom

Denmark has a mission-critical 450 MHz LTE network operated by Cibicom, built on Nokia infrastructure – the same vendor and architecture as the German 450connect network. The Danish network serves essential services providers.

Sweden and Finland

Both Sweden and Finland are active in licensing 450 MHz spectrum for energy and public safety use. Deployment status varies by operator and region.

The Global Picture

The 450 MHz Alliance tracks spectrum licensing and deployment activity worldwide. LTE bands 31, 72, 73, 87, and 88 covering the 400-450 MHz range are in use or under active licensing across all major regions:

Africa, Asia-Pacific, Europe, the Middle East, Latin America, and Oceania all have national authorities that have licensed or are licensing 450 MHz for private or dedicated LTE networks, primarily targeting utilities and critical infrastructure. The United States takes a different approach – the 450 MHz band is not widely available there, with private LTE for utilities running on 900 MHz (Anterix) and shared CBRS spectrum at 3.5 GHz instead.

The pattern across markets where 450 MHz is available is consistent: energy utilities recognise that commercial mobile networks were not designed to the resilience specification their operations require, and sub-GHz private spectrum is the practical answer.

What to Do if Your Site Is Not Yet Covered

During the rollout phase – which for 450connect runs through to full nationwide coverage in 2026 – some sites will fall outside the current footprint. This does not mean LTE450 hardware is premature for those sites.

Most whitelist-approved LTE450 routers also support standard LTE and dual SIM operation. A device installed today can operate on standard LTE where 450connect coverage is not yet established and switch automatically to LTE450 once coverage reaches the site – without hardware replacement. This is the configuration INSYS icom specifically recommends for MRX LTE450 deployments during the rollout phase.

The practical approach for a new deployment at an uncovered site:

• Confirm whether commercial LTE coverage exists at the location
• Deploy a dual-SIM LTE450 router configured to use standard LTE as primary
• Install a combination antenna covering both 450 MHz and standard LTE frequencies
• Register with 450connect (or ArgoNET) and obtain an LTE450 SIM ready for activation
• When 450connect coverage arrives at the site, switch the primary SIM without changing hardware

This means procurement decisions do not need to wait for coverage to catch up. The hardware investment is protected regardless of the rollout timeline at any given location.

See the antenna guide for guidance on combination antennas that cover both frequency ranges without separate installations.
