Sophia Antipolis, France, 24 November 2025
The event brought together more than 180 delegates from vendors and observers, including over 100 onsite participants from 20 countries, complemented by remote attendees. With 96 testing sessions, the ETSI Plugtests™ achieved 95.5 % interoperability success rate across tested configurations. The observer programme featured presentations, roundtable discussions, and demonstrations from railway operators, regulators, and public safety agencies. Insights from these events are shared with 3GPP and ETSI technical groups to provide feedback and help improve standards.
Testing covered Mission Critical Services (MCX) over 5G networks for railway and public safety applications in line with 3GPP Rel-18 as well as railway-oriented features such as Adhoc Group Call, IP connectivity, interconnection and migration scenarios.
As with previous interoperability events, the feedback will help fine-tune and update ETSI TS 103 564.
By rigorously testing diverse implementations aligned with 3GPP, ETSI and IETF standards, these Plugtests™ contribute to the harmonisation of mission-critical communication services, essential for safe, reliable and efficient railway operations worldwide.
The next MCX Plugtests™ is planned for June 2026, and the next FRMCS Plugtests™ is scheduled for November 2026.

The event was co-funded by the European Union (EU) and the European Free Trade Association (EFTA).
