Use of a Trained Classifier to Predict Distance Based on a Pair of Wireless Scans

摘要

The present disclosure describes methods, systems, and apparatuses for determining the distance between two wireless scans of a mobile computing device. The distance is determined by scanning for wireless networks with a computing device. The scanning includes a receiving a plurality of network attributes for each wireless networks within the range of the mobile computing device. Further, the distance is determined by comparing the plurality of network attributes from the scanning with a reference set of network attributes. The comparing of network attributes is used to determine an attribute comparison. Finally, the distance between a position associated with the reference set of network attributes and the computing device, based on the attribute comparison, determines a position associated with the network.

主权项

1. A method comprising:
receiving information related to a scan for wireless networks performed with a computing device, wherein the information includes a plurality of network attributes for a plurality of wireless networks, wherein the network attributes include data related to a received power of a radio signal from a wireless base station for respective wireless networks of the plurality of wireless networks and a unique identification for respective wireless networks of the plurality of wireless networks; comparing the plurality of network attributes with a reference set of network attributes to determine an attribute comparison, wherein the reference set of network attributes comprises a reference received power for respective reference wireless networks of a plurality of reference wireless networks and a unique identification for respective reference wireless networks of the plurality of reference wireless networks; and determining a distance between a position from which the reference set of network attributes were obtained and a position from which the plurality of network attributes were obtained, wherein the determining is based on a correlation between the attribute comparison and a set of previously-captured attribute comparisons, wherein the set of previously-captured attribute comparisons is based on a plurality of previously-captured wireless scans.
