Methods and apparatus for calibrating RFID readers and related RFID locationing systems

Abstract:

A radio frequency (RF) identification (RFID) reader calibration system for use with a venue includes an RFID reader having a primary identifier and a plurality of secondary identifiers. The primary identifier and each of the plurality of secondary identifiers having a respective unobstructed line of sight to a point on the floor of the venue. The RFID reader calibration system also includes a data capture device configured to be aimed at the primary identifier and the plurality of secondary identifiers and to capture respective coordinates of the primary identifier and each of the plurality of secondary identifiers. The RFID reader calibration system also includes a controller configured to determine: a location of the RFID reader based on the coordinates of the primary identifier; and an orientation of the RFID reader based on the respective coordinates of the primary identifier and each of the plurality of secondary identifiers.
