Abstract:Accurate RF-based ranging is critical for location-aware wireless systems, yet no open platform exists for fair, reproducible comparison across protocols under realistic hardware impairments. Existing simulators target communication-layer metrics and lack ranging algorithms, impairment models, and positioning-specific evaluation. We present RadioRange, an open-source, positioning-first digital twin that unifies UWB, Wi-Fi, and 5G NR on identical ray-traced physical channels. The platform models eleven independently toggleable hardware impairments across three injection stages, spanning antenna-level offsets, RF circuit non-idealities, and post-compensation CSI residuals, each with documented physical models and protocol-specific defaults. Five first-path ranging detectors and three multipath identification algorithms are provided within a protocol-specific evaluation framework, enabling controlled Monte Carlo benchmarking and systematic ablation studies. The simulator is validated against real-world UWB and Wi-Fi measurements, demonstrating that the channel model captures geometry-dependent multipath bias. RadioRange-Sim is publicly available at this https URL.
