After several years of development and a rigorous testing programme carried out by Cassidian and the Romanian Ministry of Administration and Interior, fully-certified interoperability has become a reality between two TETRA systems in Romania. Information can now be shared in real time between the country’s border police and its security forces during joint operations.

An Inter-System Interface (ISI) developed by Cassidian in accordance with the TETRA interoperability standards offers extended coverage for users on both the Cassidian and Motorola (PHARE) networks. This includes access over the TETRA national platform to all locally available functions (air interface encryption, authentication, packet data services, short data messaging), as well as cross-system communications (individual calls, PABX calls and short data services between terminals connected to different networks).

Through the radio terminals’ automatic roaming feature, visiting the other network requires no action by the user. The ISI is also a key component for the integration of the Border Police automatic vehicle location system, enabling positional information to be shared with security forces using the national TETRA platform.
