Modern airplanes are equipped with hundreds of embedded sensors and actuators necessary for structural health monitoring, aircraft control, and passenger and crew assistance. These devices are typically interconnected by wires. Using wireless connections instead of wires improves flexibility of installations and reduces the airplane’s weight. Researchers from Airbus Group Innovations have been working on this topic for several years. An ongoing joint project with the University of Klagenfurt and Lakeside Labs develops and tests such in-cabin networks with focus on their robustness against undesired interference.
