Abstract:
1. A method comprising: receiving, by a server computer, a plurality of propagation-time measurements of first signals transmitted between i) one or more wireless terminals and ii) a base station, wherein the first signals propagate through at least a portion of an antenna system that is communicatively coupled to the base station, and wherein the antenna system is a distributed antenna system; generating a statistic, by the server computer, by applying a predetermined statistical algorithm to a data set, wherein the data set comprises data points that are based on the plurality of propagation-time measurements; estimating, by the server computer, a first characteristic of the antenna system based on the statistic, wherein the first characteristic is cable delay between a first antenna node in the distributed antenna system and a predetermined component of the base station, and wherein the estimating of the first characteristic is based on the position of a first local maximum in the data set; and transmitting the first characteristic, by the server computer, to an application engine.
