Radio-frequency identification (RFID) locationing systems and methods for locating one or more items positioned within a defined space

Abstract:

Radio-Frequency identification (RFID) locationing systems and methods for locating one or more items positioned within a defined space are disclosed herein. An example embodiment includes energizing, by an RFID reader having an RFID antenna, an RFID tag corresponding to an item positioned within a defined space. Each of a first signal strength and a second signal strength of the RFID tag is detected, respectively, by a first RFID receiver node of a first node channel and a second RFID receiver node of a second node channel. A controller alternates a multiplexor to receive at the multiplexor each of first signal strength data from the first RFID receiver node and second signal strength data from the second RFID receiver node. The first signal strength data and the second signal strength data is provided to the RFID reader and combined to determine a location of the item positioned within the defined space.
