The update of the Civil Protection analog network
Since 2004, the Emilia-Romagna Region and its Regional Authorities (Municipalities, Provinces, Unions and also the Civil Protection Agency, ARSTPC) have unified the PMR (Professional Mobile Radio) communication system for emergency and safety with the ERretre TETRA digital network. The result has been a benefit in terms of operational and maintenance costs. The TETRA digital system has since replaced a costly and dishomogeneous aggregate of analog networks for the institutional system, which were inefficient and easily subject to interference and interception.
