FREQUENTIS successfully tests VoIP for ATS in collaboration with DSNA and DFS

For many years, Frequentis has been a driving force behind the standardisation of voice services on IP-based transport infrastructures in civilian air traffic control. DSNA and DFS, together with Frequentis and radio manufacturers, stepped forward to assess the operational feasibility of the outcome of EUROCAE Working Group 67.
A test platform was installed and configured between the two Air Navigation Service Providers sites in Toulouse (France) and Langen (Germany). Joint field trials demonstrating IP based ATC radio and telephone communications as well as legacy system integration were successfully completed in late 2009. With a strong presence of Frequentis, the worlds market leader in voice communication systems for air traffic control, the trials confirmed the readiness of VoIP (as defined in EUROCAE WG67 specifications) for deployment in an operational environment. Gateway test illustrated that existing legacy systems can be integrated within an IP network infrastructure and most impressingly conducted: the world's first radio communication "across the continent based on IP technology which is successfully proved under several operational scenarios performed using the test platform. The test phase of the field trials involved more than 230 VoIP Air Traffic Services related tests, each performed by DSNA and DFS within a simulated operationa environment. Frequentis was a core member of the project team. The results show that:
  • EUROCAE recommendations can be implemented successfully in ATS operations,
  • IP radios will become available in the near future,
  • The natural technical limitations of the related technology pose no constraint to implementation.
