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.
