RFID READER AND METHOD FOR IDENTIFYING RFID TAG THEREOF AND APPARATUS FOR ANALYZING RECEPTION POWER PATTERN

摘要

PURPOSE: An RFID reader, an RFID recognition method thereof and a receiving power pattern analysis apparatus for improving the recognition rate of an RFID tag are provided to reduce the recognition rate of an RFID tag which the receiving power pattern analysis apparatus does not desire. CONSTITUTION: A tag signal transmitted from an RFID(Radio Frequency Identification System) tag is received(S710). The received power is extracted from a tag signal(S730). A power pattern is generated by using the received power(S740). It determines whether the RFID tag transmitting the tag signal is recognized by using the power pattern(S760). The tag information is stored from the tag signal.
