PRAGUE, CZECH REPUBLIC, November 2026 — European emergency services and technology providers have taken another step towards strengthening cross-border interoperability, following a major European Union Critical Communications System (EUCCS) pilot trial held in Prague this November.

Organised by NAKIT, in cooperation with BRK and PSCE, the exercise brought together approximately 130 participants from 22 countries, including public safety practitioners, government representatives, European institutions and leading Mission Critical Communications (MCX) technology providers.

The trial was designed around a realistic emergency scenario involving the disappearance of an eight-year-old girl near the German-Czech border. The scenario was based on an actual incident faced by German and Czech police in 2021, highlighting the operational challenges that arise when emergency responders from different countries need to coordinate their actions across national borders.

By recreating this scenario, the EUCCS pilot trial provided a practical environment to assess European cross-border communications interoperability and demonstrate how different MCX systems can support coordinated emergency response operations.

Multi-Vendor MCX Interoperability Under Realistic Conditions

A key element of the exercise was the participation of multiple MCX technology providers, including Leonardo, Frequentis, Airbus and Teltronic.

The trial was conducted across two configurations, with communications tested between all interconnected testbeds. This enabled participants to evaluate interoperability across different technology environments and assess the ability of emergency services to maintain coordinated communications regardless of the underlying vendor platform.

The operational exercise involved 33 practitioners from 11 countries, representing police, fire and rescue, ambulance services and mountain rescue organisations. Their participation helped ensure that the trial reflected the practical communications requirements of frontline emergency responders.

In addition to operational participants, approximately 30 VIP representatives attended, including delegates from the European Commission's DG ECHO and DG HOME, the European Parliament, Europol, the European Union Agency for the Space Programme (EUSPA), the GSMA and national authorities.

Cross-Border Interoperability: A Critical Requirement for European Public Safety

The Prague exercise underlined a fundamental requirement for Europe's evolving mission-critical communications landscape: emergency responders must be able to communicate and coordinate effectively across national borders, organisations and technology platforms.

As European public safety agencies continue their transition towards broadband-based Mission Critical Services (MCX), interoperability between different national systems and vendors will be essential to supporting large-scale emergencies, cross-border incidents and multinational operational cooperation.

The EUCCS pilot trial demonstrated the importance of validating these capabilities through realistic operational exercises, bringing technology providers, public safety practitioners and European stakeholders together in a shared testing environment.

When lives are at stake, communication failures and technology fragmentation must never become obstacles to emergency response.

The organisers expressed their appreciation to all participating organisations and practitioners, with particular recognition for NAKIT and the partners involved in delivering the exercise.

Further video footage and photographs from the Prague trial are expected to be released shortly.
