A new technology based on IEEE 802.16e should be applied for airport data link applications. To determine the most adequate parameters for the physical layer system design, it is important to consider the propagation channel characteristics. The paper presents results of the channel measurement campaign at Munich airport, in the C band. Using a test signal of 120 MHz bandwidth, large number of channel transfer functions were recorded and the channel characteristics evaluated in terms of number of uncorrelated multipath components, delay spread, total Doppler spread, coherence bandwidth and time. Section II describes the channel measurements and in Section III the channel parameters are evaluated for one of the measurement scenarios - a typical AC movement between parking position and taxiway. Section IV summarises statistical results obtained for the apron area (APRON), parking positions (PARK), taxi-ways (TXWY) and runways (RWY) in view of redundancy needed for an equalisation. Section V concludes the paper.
