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： According to the present invention, the apparatus receives a radio frequency (RF) signal transmitted from the Radio Frequency Identification (RFID) reader, measures the strength of the received RF signal, and controls the power supplied from the power supply unit included in the tag or the power excited by the RF signal to be supplied to the tag according to whether the power excited by the received RF signal exceeds a level necessary to operate the tag based on the measured strength of the RF signal. Thus, efficiency of power consumption of the tag and the RFID transmission/reception system can be maximized and the amount of data is reduced to the extent that the set of commands is not needed, thereby simplifying a data process.

摘要： A battery-powered RFID tag capable of reducing power consumption and a method of waking up the RFID tag are provided. The battery-powered RFID tag has an activated mode where a general command is detected by decoding a signal received from an RFID tag reader and the general command is executed and a standby mode where the general command is not detected. If a voltage of a continuous wave detected from the signal is equal to or higher than a predetermined voltage or if a wake-up command is detected from the signal, the state of the RFID tag is changed from the standby mode to the activated mode. In addition, the RFID tag is driven by a higher one between the voltage of the continuous wave and a voltage of a built-in battery.
