Researchers have developed GLocFM, a novel foundation model designed for 3D indoor wireless localization. This model uniquely integrates scene geometry, represented as a 3D point cloud, with Wi-Fi measurements to improve localization accuracy. GLocFM formulates localization as a maximum-likelihood estimation problem, using a learned scoring function to match observed wireless signals against predicted spectra for candidate transmitter positions. The framework demonstrated a significant reduction in mean 3D localization error, outperforming state-of-the-art baselines by approximately 49% on both synthetic and real-world datasets. AI
