DFS selects Frequentis’ market-leading VCS3020X system for nine towers at German airports

Frequentis has been selected to provide its voice communication system VCS3020X for the German air navigation service provider, DFS, for nine airport towers including Frankfurt, Leipzig, and Berlin. The project to modernise voice communication systems will be ready to support ED-137 VoIP technology.

DFS has put its trust in Frequentis VCS for three decades and has selected it for the next phase of technology advances again.

“We have awarded the supply of voice communication systems to Frequentis and are confident that their technology and expertise fulfil the demands required of this tower project. Over the next five years nine DFS towers will be equipped with Frequentis VCS allowing us to provide continued safe and efficient tower services across Germany.” states Robert Schickling, COO, DFS.

DFS required a standard off-the-shelf product implementation for the tower voice communication modernisation project, and the application includes integrated ATIS backup and new cyber security functions, including threat detection and domain security. The system can be centrally monitored and remotely upgraded to provide the lowest total cost of ownership for DFS.

“Selecting our IP voice solution for this important multi-tower project characterises the trust and confidence DFS has in our expertise and our technology. We are pleased to be supporting such an important project that demands forward-thinking solutions for a range of demands”, says Hannu Juurakko, Vice President ATM Civil, Frequentis.
