Abstract
Embodiments herein describe aggregating RFID events before determining a location of an RFID tagged item. For example, a warehouse may be divided into different zones in which the RFID tagged item is tracked. An inventory tracking system may require that at least one RFID reader detect the RFID tagged item a threshold number of times before determining that the item is at the location corresponding to the reader. Thus, even if RFID readers at neighboring locations in the zone also detect the RFID tagged item, the inventory tracking system determines the location with the most RFID events is the most likely location of the package. By aggregating RFID events, the inventory tracking system can provide a more accurate location of the RFID tagged item in a noisy environment or an environment with a high density of RFID readers.
