A location and tracking system has wireless base stations, an input interface, and a processor. It receives initial physical environment inputs for an environment, with default signal attenuation values for wall and obstacle segments. An initial channel parameters fingerprint of projected signal strengths in the environment is generated according to the initial physical environment model. The processor simulates motion of the node along a htrajectory to create a corresponding fitness function describing how similar the channel parameters estimated along the htrajectory by the prediction model are to gathered channel parameters by the mobile node along its trajectory. The model and the fingerprint are subsequently modified in iterations as possible mobile node trajectories are determined to perform location error estimation which takes into account the re-calculated fingerprint and gathered channel parameters and the htrajectory as a ground truth.
