SYSTEMS AND METHODS FOR GEOGRAPHIC POSITIONING USING RADIO SPECTRUM SIGNATURES

摘要

Methods, radios, components thereof, and other devices for localizing a geographic position of a radio receiver are provided. A current radio signature is obtained. The current radio signature comprises a plurality of measured signal qualities that collectively represent a frequency spectrum. Each measured signal quality in the plurality of measured signal qualities corresponds to a portion of the frequency spectrum. The current radio signature is compared with a plurality of reference radio signatures. Each reference radio signature in the plurality of reference radio signatures is associated with a global position. When the comparing identifies a unique match between the current radio signature and a reference radio signature in the plurality of reference radio signatures, the radio receiver is deemed to be localized to the global position associated with the reference radio signature.
