LOCAL POSITIONING SYSTEM METHOD AND APPARATUS

Title:

LOCAL POSITIONING SYSTEM METHOD AND APPARATUS

Document Type and Number:

WIPO Patent Application WO/2014/176494

Kind Code:

A3

Abstract:

A local positioning system uses a power delivery network throughout a facility to easily deploy inexpensive electromagnetic receivers for capturing location fingerprints from the transmission of wireless devices. These captured fingerprints are then compared with a database of similar fingerprints compiled from a facility surveying process. Location of the wireless device is inferred from the known location corresponding to that survey-derived fingerprint that is most highly correlated with the fingerprint derived from the wireless device. The known location may then be used to provide a logical mapping of the wireless device within facility floor plans or the like.
