Disclosed herein are systems, methods, and machine readable media that enable object localization with an RFID infrastructure. Localization is performed by modeling the distance-decaying behavior of received signal strength. Selection of optimally performing tag types and the use of uniformly sensitive tags of those optimal tag types further enhances localization accuracy. When these components are combined, RFID becomes a feasible way to locate moving and stationary objects in a 3D environment that includes other objects, as well as noise and signal pollution.

Real-time RFID localization using uniform, high-performance tags and related method thereof

Object localization with an radio-frequency identification (RFID) infrastructure is described. A plurality of transmission power levels established by an RFID reader can be searched to determine a measurement power level corresponding to a target. A region that includes the target can then be determined using information about a physical relationship between the RFID reader and a reference location via correlating the measurement power level to a reference power level corresponding to the reference location.
