    摘要: Provided are a mobile RFID reader and a control method thereof. The mobile RFID reader includes: a reader controller for beginning a reader operation to communicate with a tag in response to a command of a terminal controller of the wireless communication terminal; an anti-collision state machine for controlling collision among a plurality of tags, and transferring the result of communication with the tag to the reader controller; a reader transmitter for generating a reader command message decided at the anti-collision state machine, and coding and modulating the generated reader command message; a reader receiver for demodulating and decoding a tag signal received through an antenna, and reporting a tag response state to the anti-collision state machine; and a channel controller for selecting a channel to use to communicate with a tag in response to a command of the reader controller.

    摘要: Provided is a Radio Frequency Identification (RFID) reader that can minimize collision among RFID readers in an environment where there are a plurality of RFID readers within a limited operating environment by making each RFID reader select a channel at different delay time based on a random value, and a method for controlling operation of the RFID reader. The RFID reader includes a random value generating unit; a reader control unit for adaptively deciding a counter value for generating the random value; an anti-collision unit for preventing collision among a plurality of tags; a reader transmitting unit for generating a reader command message determined by the anti-collision unit, encoding the reader command message, and modulating the reader command message; a reader receiving unit for demodulating and decoding a tag signal; and a channel operation control unit for selecting a channel to be used for the communication with the tag.

    摘要: Provided are a reader-tag integrated RFID apparatus and a method for controlling the same. The apparatus includes a tag unit for communicating with an external reader, and transmitting a response signal and data corresponding to a signal transmitted from the external reader to the external reader, a reader unit for selecting a channel between other reader and the reader-tag integrated RFID apparatus with a different delay time, and communicating with an external tag using a random value to minimize collision; and a controller for selectively activating one of the tag unit and the reader unit if it necessary.
