Claim Text:
1. A method comprising: receiving, by a server computer: estimating, by the server computer, the location of the first wireless terminal based on the evidence of the location of the first wireless terminal; estimating, by the server computer, a first spatial displacement between the first wireless terminal and the first base station, based on the estimated location of the first wireless terminal; generating, by the server computer, a statistic by applying a corresponding, predetermined statistical algorithm to a data set, wherein a first value in the data set is based on i) the first spatial displacement and ii) a first calibrated value for the first propagation-time measurement, the first calibrated value resulting from removing, from the first propagation-time measurement, propagation delay that is attributed to equipment of the first base station, and wherein a second value in the data set is based on a second calibrated value for the second propagation-time measurement; estimating, by the server computer and based on the statistic, a multipath characteristic of a wireless coverage area served by the first base station, resulting in a multipath characteristic estimate; and transmitting, by the server computer, the multipath characteristic estimate to an application engine.
