    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.

    摘要： Provided are a radio frequency identification (RFID) tag and a wake-up method thereof. The RFID tag includes: a power source that supplies a driving voltage; a continuous wave detector that receives the driving voltage from the power supply so as to detect a continuous wave in a signal received from an RFID tag reader; a command detector that selectively receives the driving voltage and detects a command in the signal; and a controller that executes the command detected by the command detector by supplying the driving voltage to the command detector if the continuous wave is detected, and stops the driving voltage from being supplied to the command detector if no command is received from the command detector for a predetermined time period.
