On the Limitations of Ray-Tracing for Learning-Based RF Tasks in Urban Environments
Researchers evaluated the realism of Sionna ray-tracing simulator for outdoor cellular networks in Rome using 1,664 real user equipment measurements across six base stations. The study found that while precise antenna geometry and positioning are critical for simulation accuracy, capturing urban environmental noise remains an unsolved challenge that limits the simulator's practical applicability for real-world RF learning tasks.
