The LTE-450 rollout by Bayernwerk Netz GmbH reaches even the most remote locations: on the Zugspitze, Germany’s highest mountain, a local substation was recently upgraded with cutting-edge technology for remote monitoring and control. The retrofit solution will allow real-time access to operating data and make it possible to track voltage and power values in the future.

At almost 3,000 meters, the Zugspitze substation is the highest power grid in Bayernwerk´s service area, supplying electricity to the Zugspitzbahn railway, the German Weather Service station and the Max Planck Society research facility, among others.

At the core of the retrofit installation is a rugged industrial router from Garderos, supporting both conventional public cellular and LTE-450 connectivity. This combination ensures secure and highly available data transmission – even under harsh alpine conditions.

Applications that Strengthen the Grid

• Remote control technology: enabling real-time monitoring and management of grid assets
• Power quality management: capturing and analyzing data on voltage and network stability
• Future-ready design: The Zugspitze project showcases today’s digital ONS capabilities. Garderos routers also support advanced features such as virtual RTUs (vRTU) for upcoming use cases

Partnership for critical infrastructure

By choosing LTE-450 and Garderos’ router as well as router configuration server, Bayernwerk Netz ensures that even remote and exposed sites are seamlessly integrated into the digital power grid. This is a vital step toward greater resilience, security of supply, and transparency in energy networks.

As one of Germany’s largest utilities, Bayernwerk Netz is a long-standing customer of Garderos. Together, the two are driving the digitalization of the energy sector – from the lowlands all the way up to the highest peaks.

Energy suppliers and KRITIS operators can officially use Garderos routers on the 450connect network. Our routers have been approved for operation in the 450 MHz frequency band, which serves as the nationwide mobile communications network for critical infrastructures. This achievement is the result of over ten years of experience developing products in the 450 MHz range, demonstrating our dedication to meeting the unique needs of German energy suppliers and KRITIS operators.

The whitelist contains voice and machine-to-machine (M2M) communication hardware tested by 450connect for interoperability and LTE450 interface quality. This hardware has been found to comply with the necessary requirements. Only devices on the whitelist are approved for operation on the 450 MHz network. This ensures maximum security, interoperability, and long-term investment protection. Garderos is proud to contribute to this effort with its industrial routers for critical infrastructures.

Full flexibility for the communications architecture

Since early 2022, our LTE- and LTE-450-enabled router portfolio has been in use with great success. Currently, over 35,000 of these dual-mode routers are securing communications for the energy industry and other critical infrastructure sectors in Germany and around the world.

In addition to 450 MHz radio modules, Garderos routers can be equipped with 3G, 4G, 5G (RedCap), DSL, and fiber optic (LWL) interfaces. These interfaces enable redundant, highly available network connections tailored for critical applications.

Furthermore, the routers can be used immediately and converted later, as soon as the 450connect network becomes available at the respective location. This process is simple and straightforward via remote maintenance. Garderos is a pioneer in remote router management with more than ten years of experience.

Strong Solutions – Strong Partnerships

As an active member of the 450 MHz Alliance, the 450 Utility Alliance, and the EUTC, we contribute our expertise in developing secure communication solutions for network operators.

Our value-added partners CANCOM, m2m Germany, Wireless Logic, mdex, and BeEnergy SG help bring our router portfolio to KRITIS customers. We greatly appreciate their support.

The Enlit Europe 2024 in Milan was a complete success for Garderos GmbH! We would like to thank all visitors for their great interest in our solutions for critical infrastructures and the diverse application possibilities of our ruggedized routers.

Great interest in durable and flexible network solutions

Our routers with a product lifespan of up to 15 years, which are characterized by high reliability, cybersecurity and easy implementation, were particularly in demand. Our visitors were impressed by the user-friendly commissioning as well as our router management server, which enables efficient, centralized management of large networks.

Another highlight was our virtual RTU (Remote Terminal Unit), which runs in a software container on our routers. It allows seamless integration of Modbus devices and forwarding of data via MQTT or IEC-104 – a solution that is of particular interest to energy suppliers, smart grids and Industry 4.0 applications.

Thanks to the organizers and our visitors

A big thank you goes to the organizing team of Synergy BV and Fiera Milano SpA who ensured a professional and smooth trade fair experience. Without their support, such a successful event would not have been possible.

See you soon in Essen!

We are pleased to announce that Garderos GmbH has successfully achieved ISO 27001 certification! This is a significant step in our ongoing commitment to the highest security standards in the development and production of our router hardware and software solutions.

What does ISO 27001 mean?

ISO 27001 is an internationally recognized standard for information security management systems (ISMS). It defines clear requirements for companies to systematically manage and protect sensitive data. This includes

• Identification and assessment of security risks
• Measures for risk mitigation and continuous improvement
• Protection of confidential information of customers, partners and employees

The certification means that our customers can be sure that our IT processes, products and services meet the highest data protection and security requirements.

Why is ISO 27001 so important to Garderos?

Garderos has always focused on the security of our router software and hardware. We have been integrating strict security measures into our business processes for years. The ISO 27001 certification is now official confirmation that we guarantee information security at the highest level.

• Trust protection – protection of sensitive customer data and network infrastructures
• Cybersecurity – protection against attacks and unauthorized access to critical systems
• Compliance – meeting legal and regulatory requirements for critical infrastructures

This certification is particularly important for customers in the critical national infrastructure (CNI) sector. It ensures that our routers and network software meet the strict requirements of energy supply, telecommunications and industrial applications.

A strong team for the highest security standards

Our success would not have been possible without the exceptional commitment of our team. Special thanks go to Alfons Puhl and Stephan Wermuth, who were instrumental in implementing the certification requirements.

However, this certification is not an end point, but a further step on our journey to continuously improve our security measures. We will continue to invest in cyber security to provide our customers with innovative, powerful and secure network solutions.

Garderos – your reliable partner for secure network solutions

With the ISO 27001 certification, we reaffirm our commitment for data protection, cyber security and quality. Our customers benefit from a reliable and certified infrastructure specifically designed to protect critical communication networks.
