摘要： An apparatus and a method for performing a protocol that optimizes a transmission power in a network. The apparatus and the method perform a protocol that optimizes the transmission power in the network for point-to-multipoint communication (1:N). The apparatus includes a communication unit for sending and receiving a data packet through the air, and a control unit that outputs a control signal for controlling the transmission power according to connection information of the data packet received through the communication unit. The connection information includes a reception signal strength and/or link quality information. Since the transmission power is adjustable, communication is carried out among nodes of the network with an adequately minimum power consumption and a proper communication quality.

摘要： A channel selection method for reading tag information, a channel selection apparatus of an RFID reader applying the same, and an RFID reader. A channel selection apparatus of a radio frequency identification (RFID) reader equipped within a wireless communication portable terminal, includes a channel selection unit which selects a channel to read tag information stored in an RFID tag, and a channel determination unit which, when determining that the selected channel is not used by another RFID reader, determines the selected channel to be a channel to read the tag information. Accordingly, when a plurality of RFID readers reads out the tag information from the RFID tag almost at the same time, the interference among them can be avoided.

摘要： A mobile radio frequency identification (mRFID) reader having a receiving circuit is provided. The receiving circuit includes a local oscillator which generates a carrier signal at a predetermined frequency band; a mixer which mixes a tag signal received from a tag with the carrier signal, to lower a frequency of the tag signal; a phase adjusting block which adjusts a phase of the carrier signal by determining a phase of the tag signal; and a control block which processes the tag signal through a series of operations, and controls an operation of the phase adjusting block to compensate for a phase delay of the tag signal according to an output of the processed tag signal. Because the mRFID reader can be provided as small as a half size of a related art reader, a mobile communication terminal accommodating the mRFID reader can be compact-sized. Additionally, because the number of components for the receiving circuit decreases, not only the power consumption but also the unit price can be reduced.

摘要： When a reader of a Radio Frequency Identification (RF-ID) system sends out a command signal to the RF-ID tag and receives a response signal from the RF-ID tag, an End of Signal (EOS) of the received response signal is detected such that the next command signal can be transmitted within a time. Accordingly, response signal can be detected even under the environment of poor signal to noise ratio performance, and the EOS of the response signal from the RF-ID tag can be recognized with ease and speed.
