SESAR validation trials have demonstrated the high performance capabilities of the FREQUENTIS VoIP network solution

- Madrid/Vienna

SESAR validation trials, recently conducted by several European Air Navigation Service Providers (ANSPs) and industry partners, have successfully demonstrated the seamless integration of Frequentis VoIP equipment with 3rd party networks. These trials also provided an excellent opportunity to validate the suitability of the Pan-European Network Service (PENS) in terms of network quality.

Several ANSPs and industry partners validated the Voice over IP (VoIP) applications in the context of SESAR validation trials conducted during November 2012. The aim was to verify the suitability of Air Traffic Management (ATM) VoIP applications over the Pan-European Network Service (PENS). PENS is the ground communication infrastructure interconnecting regional ANSP networks and, as such, is the European backbone for future voice and data applications in ATM. The Frequentis VCX-IP network solution is one of the main building blocks of the legacy voice application in PENS. A major validation criteria during the trials was the integration capability of multiple systems, in accordance with the standard for the use of Voice over IP (VoIP) in ATM, EUROCAE ED-137.

The Frequentis VCX-IP integrates seamlessly with the participating ANSP networks. During the validation it successfully demonstrated its ability to provide the required performance and functional capabilities. VCX-IP provides gateway and routing capabilities for legacy interfaces and protocols typically used in safety-critical voice and data applications in ATM. It allows a step-wise migration of legacy voice services to the future-proof VoIP-based EUROCAE standard. The SESAR (Single European Sky ATM Research) Programme is the technological pillar of the Single European Sky (SES) initiative. SESAR contributes to the implementation of the SES by developing technology and procedures for a new-generation of ATM systems aiming to enhance performance by tripling the current capacity while improving safety by a factor of 10. SES goals include halving ATM financial costs and reducing the impact on the environment by 10% per flight. Frequentis is an active member of SESAR and the EUROCAE ED-137 standardisation committee.
