InnoTrans 2026: Ericsson Shows the Way to a 5G Rail Network

<p>From September 22 to 25, 2026, Berlin Messe opens its doors for InnoTrans, the world's leading trade fair for rail technology. At the center of Ericsson's presence is a topic that has occupied the European rail industry for years: the transition from the proven but technologically outdated GSM-R standard to the 5G-based Future Railway Mobile Communication System (FRMCS). Ericsson wants to show at the fair how this transformation is not only theoretically possible but practically feasible.</p>

<h2>One Standard Replaces the Next</h2> <p>FRMCS is considered the successor to GSM-R, the standard currently used especially in Europe for train radio. Development is coordinated by the International Union of Railways (UIC), together with major rail infrastructure companies and telecommunications solution providers. Unlike its predecessor, FRMCS is based on the 5G-3GPP standard and thus does not create a separate, rail-specific radio technology – a decisive advantage for interoperability and scalability.</p> <p>For rail operators, this means: Instead of an isolated radio network for rail traffic, there is the possibility of using a single, standards-based 5G network for both safety-critical train control and operational communications, trackside applications, and broadband provisioning to passengers – with predictable performance, resilience, and security.</p>

<h2>The Practical Path from Testing to Rollout</h2> <p>At the Ericsson stand, the individual building blocks of an end-to-end rollout will be made visible: from radio network and antenna planning through coverage testing and optimization to device, interoperability, and field tests along real rail routes. In doing so, the company wants to demonstrate that the path from validation to actual commissioning is not merely a theoretical construct but is concretely understandable.</p> <p>Torsten Hunte, Head of Mission-Critical Networks Rail at Ericsson, puts the industry's challenge succinctly: "Rail operators know the goal – FRMCS – but need a clear path to get there. At InnoTrans, we show how European interoperability tests and experience from real deployments can help rail operators move forward with a secure 5G network for mission-critical operations and passenger services. Beyond Europe, there are also opportunities in markets like India and Australia."</p>

<h2>More Than Just Train Radio: The Benefits of 5G in Rail Operations</h2> <p>The switch to a 5G-based network opens up the rail industry to much more than just a technical exchange of radio technology. A fully digitalized rail operation enables, among other things:</p> <ul> <li><strong>Automated Train Operation (ATO):</strong> 5G increasingly supports automated control processes and thus increases capacity on existing rail networks.</li> <li><strong>Internet-of-Things Applications:</strong> Smart, predictive maintenance of vehicles and infrastructure becomes economically viable through continuous connectivity.</li> <li><strong>Video-based Monitoring:</strong> Route monitoring and obstacle detection along the tracks benefit from powerful, low-latency data transmission.</li> <li><strong>Better Passenger Information:</strong> More precise real-time data and customized onboard services improve service quality for travelers and commuters.</li> </ul> <p>In total, these effects can allow more trains to run on the same routes than today – an argument that carries considerable weight given growing passenger numbers and limited route capacity in many European countries.</p>

<h2>Outlook: Interoperability as the Key to Success</h2> <p>The transition from GSM-R to FRMCS is a Europe-wide endeavor that requires close coordination between rail operators, infrastructure companies, and telecommunications providers. This is precisely where Ericsson's presence at InnoTrans 2026 comes in: Interoperability tests and practical rollout experience are intended to give rail operators confidence in their migration journey. The fact that, according to Ericsson, market opportunities for FRMCS-based solutions are also emerging outside Europe, such as in India and Australia, underscores the potential reach of this technological change beyond the European continent.</p> <p>For the rail industry, InnoTrans 2026 should thus be another important milestone on the long road to a uniform, future-proof communications standard – a path that brings not only technological but also organizational and regulatory challenges, but at the same time lays the foundation for safer, more efficient, and more digital rail transport in Europe and beyond.</p>
