ABSTRACT:
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.
