Abstract:
1. A method comprising: determining, by a system including a processor, a set of separating hyperplanes using historical data of known timing measurements and associated location information received from a plurality of location aware mobile devices; receiving, by the system, a reported time measurement from a non-location aware device, wherein location information is not received from the non-location aware device; applying, by the system, the reported time measurement from the non-location aware device to the set of separating hyperplanes, wherein the set of separating hyperplanes divides a field of interest into ranges of geographic coordinates; and determining, by the system, a location of the non-location aware device as a function of the applying; wherein the applying comprises: receiving a collection of timing offset measures from the non-location aware device; and assigning a location value to the non-location aware ˜ device, wherein the location value comprises location information representative of a location with respect to a geographic coordinate.
