Talk at Gdansk University, “Digital Twin for Reliable Vehicular Wireless Links”

Stefan Zelenbaba presented his work on wireless digital twins. The stringent reliability and latency constraints imposed by URLLC require the development of affordable and repeatable testing and verification methodologies. Stefan Zelenbaba explained: „We built an SDR-based multi-node wireless channel sounder to collect measurement data in complex vehicular communication scenarios. The measurement data is used to calibrate a realistic geometry-based stochastic channel model, that simulates the measured scenario. By combining our realistic channel model with the AIT real-time wireless channel emulator, we create a site-specific digital twin for testing reliable vehicular links using transmitter and receiver modems in the loop.“
