Abstract
Features are disclosed for collecting wireless identifier signals such as from RFID tags to accurately determine the location of items associated with the wireless identifier. Carefully coordinating when to begin and end collection of the signals and analysis of the signals and signal characteristics (e.g., received signal strength) allow a carried item to be identified and its location determined. Additional features are described to further validate the location of the item.
