An attractive application scenario for wearable computing is the maintenance of airplanes. In this scenario, wearable computers need wireless communication with high data rates to enable mobile workers to communicate with remote assistants or to obtain video manuals from remote servers. This paper describes experiments and results of measurements with IEEE 802.11 wireless technologies in an airplane maintenance scenario. The highest throughput was achieved with IEEE 802.11g/n devices in infrastructure mode. Generally, the results are better than previously expected, as with systems operating in 2.4 GHz frequency band, communication was even possible inside the cabin without additional relay stations at the door. Among the tested technologies, IEEE 802.11g/n clearly has shown the best performance, with more than 7 Mbit/s throughput in infrastructure mode - nearly independent of the receiver's position. This data rate is sufficient for high definition video communication. Hence, the recommendation at this stage is to use IEEE 802.11g/n in infrastructure mode for communication of the mobile workers. In further work the optimal number and positions of access points for the support of multiple workers needs to be identified.
