Abstract:
Embodiments of the present invention include radio frequency identification location systems and methods. In one embodiment, RF signals are transmitted from one or more RFID readers, and in accordance therewith, backscattered signals are received from a tag to be located. A plurality of measured position parameters are used to determine a location of the tag. In one embodiment, one reader may transmit and three readers may receive signals to determine the position of a tag. In other embodiments, multiple readers may transmit and receive. In another embodiment, one reader may transmit from different positions to locate a tag. Embodiments of the invention may be used to track a moving tag. A reader's position may be determined using GPS, reference tags, or the reader may be positioned in a known location. A map may be provided to a user to display the location or movement of a tag or a corresponding item.

Claim (Index 70):
A device for locating radio frequency identification tags comprising:\n an RF signal transmitter for transmitting one or more RF signals to a tag; a backscattering receiver for receiving one or more backscattered signals from said tag; a position parameter measurement unit for extracting one or more measured position parameters from each backscattered signal; and a communication unit for establishing a data communication link between said device and an external system, wherein measured position parameters obtained from at least three backscattering signals from said tag from at least three different positions are used to determine the location of said tag.
