TETRA system and radio relay network

The TETRA system is used as a unified radio communication system to provide a communication environment for management, interaction and coordination in the Ministry of Interior as well as other government structures responsible for crisis prevention, disasters and national security issues.

With EUR 63.7 million of financing from the Recovery and Resilience Facility, this measure will help achieve national coverage of the TETRA system of the Ministry of Interior, increase the number of subscribers of the system from all state institutions and improve the capacity and quality of services. The envisaged radio coverage of the TETRA communication system shall reach 90% for portable TETRA radio terminals and 95% for mobile TETRA radio terminals on the territory of Bulgaria.

Two contracts for the development of the TETRA system were signed in 2022, following open and competitive tenders.

The implementation of this measure has been completed.
