UWB connectivity in industrial environments

The introduction of wireless connectivity in industrial environments promises a rapid and cost-effective reconfiguration of machines and sensors. A key question in this context is: Which wireless technology is best suited for industrial settings? Many of the prevalent technologies, like WiFi and ZigBee, do not meet the requirements of certain industrial applications in terms of data rate, power consumption, and robustness. The lack of alternatives capable of achieving a good balance between these conflicting goals impedes progress. This is why researchers from the University of Klagenfurt, Airbus, and Lakeside Labs investigate the use of ultra-wideband (UWB) communications for wireless connectivity in industrial environments. Interestingly, UWB is commonly used for localization but is not yet an option for communications. Experiments with IEEE 802.15.4-2011 UWB devices were conducted in two industrial scenarios, namely a large-size aircraft assembly hangar and a medium-size production hall. These measurements are the first ones reported for off-the-shelf UWB devices in such setting and shed light on the potential of UWB to support emerging industrial applications. Jorge F. Schmidt, a senior researcher in …

UWB sensor networks in airplanes

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.
