  • 15,000th Air‑to‑Ground Protocol Converter (APC) produced for the FAA’s Brand-New Air
    Traffic Control System (BNATCS)
  • Milestone supports the world’s largest aviation communications modernisation programme,
    spanning thousands of network endpoints across the US National Airspace System
  • The APC gateways enable large-scale TDM-to-VoIP conversion across the FAA’s
    BNATCS programme

Frequentis has completed the production of the 15,000th Air-to-Ground Protocol Converter (APC) for the
DOT’s Brand-New Air Traffic Control System (BNATCS) modernisation programme. The APC enables
FAA (Federal Aviation Administration) to safely migrate radios and the Voice Communication System (VCS) to modern IP-based systems.

Frequentis USA was awarded the APC contract in 2024 as part of Phase One of the FAA’s Voice over
IP Communication Enterprise (VoICE) programme. VoICE is a modernisation effort to replace ageing air
traffic control voice systems with advanced, networked Voice over Internet Protocol (VoIP)
technologies, improving safety, reliability, and operational flexibility across the National Airspace
System. The programme scope includes both APC deployments and subsequent voice switch deliveries.

The production of 15,000 APC units represents a major milestone of the FAA’s VoICE programme.

Frequentis relied on its decade-long partner ComSonics, Inc. – a Virginia-based company specialising in fully automated electronic manufacturing – to produce the APC units in the accelerated
timeline. The existing partnership with ComSonics to manufacture electronics components for critical
FAA systems in the US was a critical success factor.

In the next phase of the programme, Frequentis will begin delivering its latest voice communication
system, the Frequentis X10 VoICE. The company is currently building the first 63 X10 systems, with
deliveries scheduled to be completed in early 2027.

“Frequentis is proud to support the DOT’s BNATCS programme,” said Dieter Eier, president of Frequentis USA. “Our team moved mountains to accelerate delivery of the 15,000 APC systems, from the original eight‑year rollout plan to just 12 months, helping the FAA modernise air traffic control communications at unprecedented speed.”
