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 …

Synchronization in sensor networks using time series analysis

Time synchronization is an essential building block in wireless sensor networks but is challenging due to low-precision oscillators and limited computational power of cheap devices. A novel synchronization solution for such scenarios is now proposed by Wasif Masood together with his advisors Christian Bettstetter and Jorge F. Schmidt from the University of Klagenfurt.
