VIRVE

VIRVE is the Finnish national public safety radio network. It is a TETRA (Terrestrial Trunked Radio) based system designed to provide secure and reliable communication for emergency services and other authorities. The network is operated by Suomen Virveverkko Oy, a company owned by the Finnish state.

The primary users of VIRVE include the police, rescue services, ambulance services, and border guards. It allows these organizations to communicate with each other directly or through dispatch centers, ensuring efficient coordination during critical incidents. The system supports voice calls, group calls, and data services, enabling the transmission of information such as text messages and location data.

Security is a key feature of VIRVE, with encryption protocols implemented to protect sensitive communications. This ensures that only authorized personnel can access the network and its transmissions. The network is designed for high availability and resilience, meaning it can continue to operate even in challenging conditions or during widespread network outages affecting commercial telecommunications.

VIRVE also facilitates interoperability between different public safety agencies. This is crucial for coordinated responses to major events, natural disasters, or cross-border incidents. The network is continuously updated and maintained to meet the evolving needs of its users and to incorporate technological advancements in public safety communication.
