Wireless sensors and the corresponding wireless data communication networks will play an important role in future aircraft cabin technology. Several applications are of great scientific and practical interest. Wireless data communication networks are able to provide more comfort to the passengers, reduce the wiring harness, lower the maintenance costs and reduce system weight. Furthermore, they allow a more flexible and efficient cabin design. Such network may consist of up to a thousand of individual sensors. Thus the coordination and organization of such a wireless cabin data communication network is a challenging task. In this paper, two different system concepts are proposed and discussed. They both provide a reliable access to the radio channel but operate differently in interference situations, which will occur while the aircraft is on ground. CONCLUSION This paper introduced two concepts for radio channel access of a wireless cabin data communication network and discussed their benefits. Besides many other challenging tasks the design of a suitable radio channel access method for such a network is one of the most challenging ones. Two methods for radio channel access have been proposed. Both proposals fulfill the basic requirements of the individual applications and on the overall system reliability. However, they differ in complexity and show a different behavior in the interference situations. While the hierarchical approach offers simple complexity and an almost deterministic behavior, it has the disadvantages in interference situations. The self-organizing approach offers an almost immediate reaction toward interference but is overall a more complex approach as all the sensors have to operate autonomously. In general the wireless cabin data communication network has to work properly during all possible environment conditions, whether it is up in the air or down on the ground. Therefore the self-organizing approach is a more suitable solution since it offers high flexibility and a better performance in interference situations.
