Subproject "Simulator and SDR of DECT-2020 NR" (SimSDR) as part of the collaborative project “Ultra scalable wireless access” (USWA)

Abstract

The USWA project was initiated to address the growing demand for ultra-reliable and low-latency wireless communication in industrial and media applications, where existing technologies like 5G URLLC cannot yet satisfy requirements such as sub-millisecond latency and extremely high reliability. Use cases include collaborative robotics, autonomous transport, industrial internet of things (IIoT), and immersive media. The project investigated novel 6G concepts focusing on cooperative radio operation, mesh topologies, intelligent resource utilization, and enhanced reliability based on DECT NR+. Leibniz University Hannover developed a flexible network simulator for analyzing URLLC in mesh networks and implemented a software-defined radio platform for DECT NR+ in collaboration with project partner RFmondial, providing one of the first practical research implementations of this emerging standard.
