Abstract
We refer to a technology stack employing DECT NR+ for vehicular communication as D-V2X, emphasizing that DECT NR+ is compatible with (and exploits features of) 5G NR of Cellular Vehicle-to-Everything (C-V2X), but – unlike C-V2X – it was designed to operate in unlicensed spectrum and without infrastructure support in a true ad-hoc manner. Yet, despite its promising characteristics, DECT NR+ remains unexplored for vehicular communication. Our system-level simulation study demonstrates that DECT NR+ can be a viable basis for vehicular communication, achieving communication windows of approximately 10 s for relative speeds of 120 km/h. Our work also reveals many open research questions that require investigation. We also describe the design and validation of the underlying first publicly available open-source physical/MAC layer model of DECT NR+. We based it on the well-established Veins framework for vehicular network simulation, enabling researchers to evaluate DECT NR+ performance in realistic traffic scenarios. We validate the model through both analytical comparison with the standard and experimentally using real hardware.
