BRUSSELS — The European Critical Communication System (EUCCS) has entered its fourth preparation phase, marking another step towards establishing a robust, broadband communications foundation for authorities and organisations responsible for public safety and security across Europe.

Experts and stakeholders from across Europe are meeting in Brussels this week for the official kick-off of EUCCS Preparation Phase 4, which is planned to run for two years. The programme supports the practical, technical and operational development required to translate the EUCCS vision into a functioning cross-border communications capability.

The project proposal for Phase 4 was recently approved by the European Commission, enabling stakeholders to move forward with more detailed technical and operational consultations. Key areas of work will include the development of applications, workflows and other requirements designed around the needs of future users.

A major focus of the Brussels discussions will be the planning of the next series of EUCCS field trials. These exercises will bring together cross-border teams to simulate real-world communications between public-safety and security organisations operating across national boundaries.

During the trials, participating teams will evaluate technologies supplied by selected industrial partners under realistic operational conditions and across a range of application scenarios. The exercises are intended to provide practical insight into the interoperability, usability and operational performance required for future European critical communications.

The most recent major EUCCS field trial was conducted in March 2026 in Aschaffenburg, Germany, bringing stakeholders together to test cross-border communications capabilities in a realistic environment.

Germany, alongside other EU and Schengen countries, continues to play an active role in shaping the development of EUCCS during Phase 4. The Federal Agency for Public Safety Digital Radio (BDBOS) participates as a National Competent Authority within EUCCS and is represented at this week's Brussels kick-off to actively contribute to the programme's ongoing development.

With Phase 4 now underway, EUCCS is moving closer to its objective of providing a secure, resilient and broadband communications environment capable of supporting cross-border cooperation among Europe's public-safety and security organisations.
