    摘要: Disclosed is a method for identifying a plurality of moving tags by using a plurality of Radio Frequency Identification (RFID) readers. The technology of the present invention efficiently identifies multiple moving tags to thereby improve the identification rate and reading speed of an RFID system and increase the throughput of the RFID system. The method for identifying a plurality of moving tags by using a plurality of Radio Frequency Identification (RFID) readers includes the steps of: a) grouping the multiple tags into a predetermined number of tag groups; b) allocating the tag groups to the RFID readers respectively; and c) identifying tags of each allocated tag group in each RFID reader.

    摘要: Provided are a media access method and a reader for performing the media access method in a dense reader environment. The media access method divides an air time between the reader and a tag into a plurality of time slots, and operates in each of the plurality of time slots by using a listen before talking (LBT) technique. The plurality of time slots form a frame. Thus, the media access method can control the reader by performing channel scheduling between each of a plurality of readers and can efficiently recognize tags.
