METHOD AND APPARATUS FOR DETERMINING LOCATIONS OF ACCESS POINTS

摘要

Methods and apparatuses for determining locations of a plurality of access points (APs) are presented. In some embodiments, the method includes obtaining measurements from at least 3 measurement points using a mobile device, wherein the locations of the at least 3 measurement points are unknown and are at different locations. The method may also include computing distance measurements from the mobile device to each of the plurality of APs, at each of the at least 3 measurement points, using the measurements, computing a set of mutual distance values in a matrix of mutual distances between each of the plurality of APs, using the distance measurements, and determining the locations of the plurality of APs using the computed matrix of mutual distances, relative to the at least 3 measurement points.
