In order to utilise state-of-the-art equipment, three airports of the United Kingdom have decided to opt for Frequentis’ air traffic control communication systems. Frequentis of Austria is a leading supplier of communication and information solutions for safety-critical applications all over the world. Indian Eastern railways and Indian Coast Guards are among its clients too. The company will be replacing the existing systems of the airports with brand new installations and upgrading equipment. The airports are East Midlands, SCATSTA-Shetland and London-Southend.
