RFID sensor array

摘要

A method of monitoring an environment in which a radio frequency identification (RFID) system tracks the movement of articles through a supply chain is disclosed. Each article having attached thereto an RFID tag. First information is received that comprises the signal strength of a detected radio frequency (RP) signal at one or more of a plurality of RFID readers (readers) that are located within the environment. The received first information is sent from one or more detecting readers that were not attempting to read any RFID tags while the RF signal was being detected. Values representing a level of interference with RFID system performance are stored into a memory device. Each stored value is based on the received first information.
