Researchers have developed GeNeRT, a novel framework for wireless channel modeling that integrates physics-informed neural networks with generalizable neural ray tracing. This approach enhances accuracy and generalization by incorporating relative geometric features, scatterer semantics, and a Fresnel-inspired polarization architecture. GeNeRT employs a three-stage training strategy, including module-wise pre-training, end-to-end system training, and measurement-based fine-tuning, to capture complex ray-surface interactions and site-specific propagation characteristics. Simulations show GeNeRT significantly outperforms existing methods in both intra-scenario transferability and inter-scenario zero-shot generalization, achieving substantially lower overall and average-delay errors.
