In 2009, EUROCAE Working Group 67 (WG-67) released its specifications for VoIP (Voice over IP) in air traffic management (ATM) communications. Frequentis has contributed significantly to these standardisation activities. Given its continuing position as a leader in communications technologies for ATM, the company has now also joined the EUROCONTROL's VOTE (VoIP in ATM Implementation and Transition Expert) Group.
February 2009 saw the official release of three major EUROCAE WG-67 specifications (ED-136 to ED-138). Through its research and development activities, Frequentis has contributed significantly to these documents. The aim of EUROCAE WG-67s activities is to harmonise interoperability of VoIPbased voice communication systems in ATM communications across the globe. This will contribute to increased flight safety and reduce the costs of the next generation of ATM programs and initiatives, such as SESAR in Europe and NEXTGEN in the United States. In late 2009, successful field trials held by the French (DNSA) and German (DFS) air navigation service providers confirmed the maturity of the EUROCAE WG-67 specifications for VoIP in ATM, as regards deployment in an operational environment. Frequentis participated in the tests with its latest VoIP-based VCS 3020 voice communication system, as did other major ATM radio manufacturers. Leading next generation voice communications for air traffic control In late 2009, Frequentis joined the newly-formed VOTE subgroup (VoIP in ATM Implementation and Transition Expert Group) established by the EUROCONTROL Communication Team. The VOTE group will address validation, transition and deployment related issues related to VoIP-based communication services in ATM. The group will identify solutions and deliver recommendations to interested parties, like ANSPs, the industry, TELCOs, and standardisation bodies.
