We are happy to share that our colleague Maximilian Schuh recently attended the prestigious ACM SenSys 2024 conference, a flagship event in the field of networked sensing systems, where he had the honor to present our paper entitled "Understanding Concurrent Transmissions over Ultra-Wideband Complex Channels".

The research presented in this paper, conducted in cooperation with the Technology Innovation Institute, focuses on characterizing and improving the performance of concurrent transmissions over ultra-wideband (UWB) complex channels, which were previously known to be unreliable. The paper's results unlock solutions to the growing scarcity of available UWB channels and pave the way for highly-scalable UWB systems.

Max and his colleagues have conducted a large-scale experimental campaign to explore the root causes of packet loss during concurrent transmissions across different complex channels. Their findings highlight methods to significantly improve reliability (i.e., sustaining more than eight concurrent UWB transmissions on the same frequencies with a packet reception rate above 99%) while preserving the excellent ranging capabilities that make UWB technology so promising.

Congratulations to Max and his colleagues for this remarkable contribution to advancing UWB technology and for representing our institute on such an important global stage!
