Bridging Visual and Wireless Sensing via a Unified Radiation Field for 3D Radio Map Construction

ArXi:2601.19216v2 Announce Type: replace-cross The emerging applications of next-generation wireless networks demand high-fidelity environmental intelligence. 3D radio maps bridge physical environments and electromagnetic propagation for spectrum planning and environment-aware sensing. However, most existing methods treat visual and wireless data as independent modalities and fail to leverage shared electromagnetic propagation principles.
