Abstract
Radio frequency fingerprints may be received, for a plurality of computing devices, comprising indications of detected wireless access points and signal strengths of the detected wireless access points. Access point distances between a plurality of wireless access points may be computed based on the radio frequency fingerprints. One or more neighboring wireless access point pairs may be detected, based on the radio frequency fingerprints, each including two wireless access points that are detected by a same computing device. One or more relative positions may be determined of one or more of the plurality of wireless access points relative to one or more other of the plurality of wireless access points based on the access point distances and the one or more neighboring wireless access point pairs. A location-based operation may be performed based at least in part on the one or more relative positions.
