Location tracking of a wireless device.

A computer-implemented method for tracking a communication device moving through an indoor environment; the method includes: i) obtaining channel impulse responses, CIRs, between the communication device and anchor devices along multiple propagation paths; ii) determining an a priori distribution of the location of the communication device within the environment; iii) determining from the channel impulse responses conditional distributions of the range-related measurements conditioned on a range between a potential location of the communication device within the a priori distribution and the respective anchor devices along respective line of sight, LoS, and first order propagation paths; and iv) estimating the location of the communication device as the potential location for which a combination of the a priori distribution and the conditional distributions is maximized.
