<p>To estimate a tag read status of a passive RFID system in an actual operation environment. A method for estimating, by simulation, a tag read status of an RFID system comprises the steps of calculating the power supply activation status of each of one or more tags having IDs within a range in which the tag moves; and analyzing the operation of a collision avoidance protocol provided in the RFID system. The tag has a state parameter representative of the state of the tag. For a command signal in conformance with the collision avoidance protocol, the operation and state parameter of the tag are changed in accordance with the power supply activation status when the command signal is being processed in the tag.</p> |
