Abstract
Disclosed is an automated item tracking method, comprising the steps of reading an RFID signal, obtaining a reported position of an RFID signal generator, measuring the strength of the read RFID signal, creating a read profile, obtaining a physical package profile, comparing the read profile to the physical package profile, and generating a weighted read profile to estimate an actual position of the RFID signal generator by comparing the weighted read profile with the physical package profile.
