When communication must never become a weak point
A reliable and stable energy and water supply are essential foundations of a functioning society and economy.
Power and water networks are becoming increasingly decentralised, digital and automated. Renewable energy sources feed in intermittently, e-mobility increases consumption, and more and more installations need to be monitored and controlled remotely.
This makes a reliable communication infrastructure even more important.
At the same time, many installations are located where conventional cellular networks are difficult to reach. And if a primary connection such as DSL or fibre fails, communication still has to continue.
LTE450 provides an additional, robust communication option for precisely this purpose.
As an expert in the energy and water supply segment, we are committed to mastering these challenges with our intelligent and powerful hardware and software solutions.
Cellular reimagined. For critical infrastructure.
Decades of experience meet the opportunities of LTE450.
“For decades, I’ve been closely involved in the development of cellular devices — today as a product manager. What I find particularly exciting is Germany’s current pioneering role in LTE450, helping to rapidly digitalize critical infrastructure and make it more resilient in times of crisis.”

Use cases of LTE450
Better penetration to hard-to-reach locations
LTE450 offers excellent mobile network coverage due to the frequency bands in the 450 MHz range. These long-wave frequencies have a much wider propagation and increased penetration of obstacles than the much shorter radio waves of standard mobile communications. This is particularly helpful for locations that are difficult to reach by radio and often enables radio coverage underground, in basements or shafts. Even installations in rural areas with previously insufficient standard network coverage can be reached by LTE450. Since these conditions often apply to facilities in the energy and water industry, the use of this frequency band is well tailored to the requirements of critical infrastructure.
Fallback when DSL or fibre connection is cut
More often than one might suspect, lines are cut, especially by excavation work, which interrupts the connection. In this case, systems in critical infrastructures have a failover function so that uninterrupted communication can be guaranteed. In the event of a line disconnection, the system automatically connects to the mobile network.
Secure even in times of crisis
The LTE450 networks are designed to ensure a secure radio connection even in times of crisis. Also in the event of nationwide power failures (blackouts or load shedding), LTE450 continues to be available through emergency power supplies. Even flood scenarios are covered by prudent siting of the radio masts and a flood-proof communication link. To rule out congestion in an emergency, there is well-considered network planning for each radio cell and, if necessary, prioritisation of applications with high criticality.
Secure. A flexible solution.
LTE450 does not have to be used as the sole connection. The modular MRX routers allow the technology to be combined flexibly with other access technologies – and adapted precisely to the requirements of your installation.
One solution, multiple connections
LTE450, standard LTE, DSL or fibre: The modular MRX routers allow different access technologies to be combined. If one connection fails, an alternative connection can take over. This allows the communication infrastructure to be designed redundantly and availability to be increased.
Easily retrofit LTE450
Already using an MRX router?
The MRcard PL450 makes it easy to retrofit LTE450. Existing hardware can continue to be used and expanded with an additional access technology.
Combine LTE450 and standard LTE
Two networks, greater flexibility: LTE450 and standard LTE can be used together. LTE450 can be used for critical communication tasks, while standard LTE is available, for example, for applications with higher data volumes. Dual SIM allows switching between the connections depending on the application and requirements. This allows you to combine the high availability of LTE450 with the flexibility of the standard LTE network.

Membership of the Versorger-Allianz 450
The Versorger-Allianz 450 Beteiligungs GmbH & Co. KG is an association of more than 200 energy and water utilities. As a shareholder of 450connect, it is driving forward a crisis-resilient 450 MHz mobile network for critical infrastructures.
Since 2025, INSYS icom has been a member of the Versorger-Allianz to engage in a joint dialogue on 450 MHz technology, installations and best practices, and to advance LTE450 technology.
German provider for our LTE450 solution
The provider 450connect is expanding the fail-safe and highly available 450 MHz radio network. It offers operators of critical infrastructures comprehensive security of supply and smooth operation. Thanks to the good propagation characteristics of the 450 MHz frequency band, comparatively few antenna sites are required, enabling rapid expansion.
Since early 2025, INSYS icom has been listed on the 450connect whitelist* with its modular MRX LTE450 router, making it one of the first three industrial router manufacturers to be officially approved by the German network provider for the 450 MHz radio network for critical infrastructure.

LTE450 – Frequently asked questions
What is the availability of the LTE450 network in Germany and Austria?
The German provider 450connect has achieved over 90% network coverage since December 2025. Complete nationwide coverage is planned for 2026. The Austrian provider ArgoNET offers coverage in many parts of the country and is also working on further expansion.
I need to modernise, but LTE450 is not yet rolled out at my location – what can I do?
If there is other mobile coverage at the planned location, this can be used to operate with the LTE450 router. Our LTE450 devices additionally support the existing mobile radio technologies and also offer a switching option by using two SIM cards. When alternately using LTE450 and standard mobile radio, make sure to use a combination antenna that supports the higher standard LTE frequencies in addition to LTE450.
How can I integrate LTE450 into our existing infrastructure?
The modular router MRX is easily expandable with the MRcard PL450 and can be combined with common access technologies such as DSL and fibre.
Do I have to use LTE450?
So far there are no obligations to use LTE450. However, it is becoming apparent that LTE450 will become a de facto standard for critical installations in the energy and water sectors. There is also the possibility that the associations operating there will then issue recommendations for action regarding the use of LTE450.
Are LTE450 SIM cards available to everyone?
LTE450 SIM cards are only available for players in the critical infrastructure sector. In Germany these are distributed by the provider 450connect and in Austria by ArgoNET. INSYS cannot distribute the cards further, but can carry out a pre-installation of the SIM card if required when the routers are delivered.
Is LTE450 another new hype that will die out in a few years?
No! Although many different radio standards have appeared and partially disappeared in the IoT sector in the last decade, this does not apply to LTE450. The radio service for critical infrastructures is designed by the provider 450connect for a minimum availability until 2040.
The technology is new, does INSYS already have enough experience with it?
LTE450 is based on the well-known LTE technology, so there is no risk of major “teething problems”. Our proven suppliers are already using LTE450 abroad and we are in close exchange with European providers and key customers, some of whom have several years of experience through test installations.
The LTE450 network is not yet available everywhere, but I need to equip installations soon. How can I avoid buying devices twice within a short period of time?
INSYS LTE450 routers also support standard cellular communication and can therefore already be operated on standard cellular networks before LTE450 network coverage is available. While you will not initially benefit from the advantages of LTE450, you will already be well prepared for the future and have made a long-term, sustainable investment.
Do I need a special antenna for LTE450?
Yes, because the frequency bands used by LTE450 at 450 MHz are significantly lower than the standard mobile radio frequency bands, which are in the 700 … 2600 MHz range. Depending on the application, either a pure 450 MHz antenna can be used or a combination antenna that also supports the frequency bands of the public mobile radio networks.
Why is LTE450 using a 4G standard, why not 5G?
5G technology has other objectives, such as very high data rates or lowest latency, which do not offer any added value for critical infrastructure applications. Therefore, the proven LTE technology is used worldwide for the implementation of crisis-proof radio networks.
Which frequency bands are used in the 450 MHz frequency range?
LTE450 uses the LTE bands 31 and 72. In Germany and Austria band 72 is currently used, in some other countries band 31. The bands consist of separate areas for uplink and downlink. Band 31: 452.5 – 457.5 MHz (UL) and 462.5 – 467.5 MHz (DL). Band 72: 451 – 456 MHz (UL) and 461 – 466 MHz (DL).
Why is the 450 MHz radio frequency so important for the energy industry?
The low 450 MHz radio frequency offers significantly better propagation compared to all other higher mobile radio frequencies and also reaches previously inaccessible installations. LTE450 thus ensures optimal radio coverage and is therefore used proprietarily for critical infrastructure in many countries. Due to the decentralised power generation through renewable energies, the energy industry is currently working on the digital transformation of its networks and therefore needs many new communication connections. LTE450 plays a key role in this.
