The aeronautical mobile airport communication system (AeroMACS) is the new-generation airport datalink to help airlines, airport authorities and Air Navigation Service Providers (ANSP) cope with increased volumes of data exchange at busy airport surfaces. AeroMACS is an international standard, operating in the aeronautical C-band (5 GHz) for short-range and high-data rate communications. It is based on the commercial 4G technology using the WiMAX standard (IEEE 802.16). It offers a broadband IP datalink with worldwide interoperability, enabling integration of critical communications for air traffic services, airline operational communication and airport authority communications.
In Europe, AeroMACS, is currently operationally deployed at Lisbon airport. Ongoing implementation activities are also taking place in other regions, including US, Japan, China and Brazil, in close coordination with the WiMAX Forum®.
