Abstract: A computer-implemented method for determining position of a mobile device using magnetic beacons including detecting, by a sensor in the mobile device, a magnetic signal having a unique signature associated with a given magnetic beacon; storing location and an associated signature for each of a plurality of magnetic beacons in a data store of the mobile device, where each of the magnetic beacons is assigned a different signature; extracting the unique signature from the magnetic signal; comparing the extracted signature to each of the signatures stored in the data store; identifying a given magnetic beacon from the plurality of magnetic beacons, where signature for the given beacon matches the extracted signature; and retrieving the location for the given magnetic beacon for the data store and correlating location of the mobile device with the location of the given magnetic beacon.
