WiWorld-Real is a real-world multimodal wireless dataset for wireless world model research. The dataset was collected through large-scale continuous measurements along 36 routes on the campus of Beijing University of Posts and Telecommunications. It synchronously records multi-view images, panoramic images, LiDAR point clouds, millimeter-wave radar data, GNSS trajectories, and wireless channel impulse responses at two industry-relevant frequencies: 3.7 GHz and 6.775 GHz. WiWorld-Real features real-world measurements, rich modalities, broad scenario coverage, and large-scale data. With unified timestamps, spatial information, and file indexing, it enables sample-level alignment and standardized organization of multimodal data. The dataset can provide a data foundation for wireless world models and foundation models, channel prediction, network planning and optimization, integrated sensing and communication, digital twins, and simulation-based testing and validation.
