    Communication Systems

    In the air traffic control community, Frequentis is a synonym for voice communication systems. Operators working on more than 12,000 positions across the globe rely on our technology, making us the world’s leading supplier.

    We provide civil and military communication solutions for any size of operation, from small standalone control towers to the largest networked ATM centres.

    Our voice communication systems are complemented by backup and simulation systems, voice/data recording systems, as well as intelligent voice/data gateways and network nodes.


    Information Systems

    Modern and safe air traffic control combines communication and decision technology with the information needed to support and execute quick and right decisions.

    Frequentis offers customisable information systems that deliver and display information in the most efficient and safe way for the users.

    Our solutions draw on the experience and expertise that saw a Frequentis-led team develop the world’s largest Aeronautical Information System (EAD) for EUROCONTROL.

    Tower Automation Systems

    With a growing variety of tower information flows, tasks and input systems, the possibility for human error increases accordingly. Inefficient work areas become cluttered with multiple screens and devices.

    Frequentis tower automation systems solve the problem with a set of tower and airport tools (TAPtools) covering all required systems from electronic flight strips to lighting control.

    These tools integrate with each other and third-party products through a standard user interface, designed to give control back to the operator.
