Abstract
AeroMACS is a system currently under development to be used for airport surface communications. It is based on the IEEE802.16-2009 standard, and is developed in cooperation with the WiMAX forum. The frequency band allocated to AeroMACS is 5091-5150 MHz. When specifying the AeroMACS system, knowledge of typical propagation conditions at airports is of importance. Typical path loss models are necessary to estimate the range of a transmitter within different zones of the airport, and typical fading characteristics are used to estimate the performance of e.g. the selected coding and modulation schemes.
