    摘要: Provided is a power control method for a mobile Radio Frequency Identification (RFID) reader and an RFID reader using the same. The RFID reader includes: an RFID reader transmission/reception control unit for creating a message to be transmitted to an RFID tag and transmitting RFID tag information to a terminal control unit; a reader transmitting unit for encoding and modulating the created message; a power amplifier for amplifying an output signal; a reader receiving unit for demodulating and decoding the signal and transmitting the signal to the RFID reader transmission/reception control unit; and an RFID reader power control unit for controlling power, wherein when the RFID reader transmission/reception control unit receives a command for acquiring the RFID tag information, the RFID reader power control unit applies power to the power amplifier.

    摘要: Provided are a method for processing reception calls during mobile RFID service processing, and a wireless terminal employing the method. The terminal provides mobile RFID service by receiving tag information from the RFID reader, requesting the object directory server for CS position information based on the tag information, requesting service contents based on the tag information and CS position information. The present invention prevents collision between reception call processing and mobile RFID service processing in the wireless terminal by processing reception call appropriately to each duration of mobile RFID service processing. For example, when a call is received before read command is transmitted to the RFID reader, the RFID reader is turned off and the reception call is processed. When a call is received before CS position information is requested, the CS position information is requested after the reception call is processed.

    摘要: Provided are an RFID reader and a method for suppressing transmission leakage signals thereof. The RFID reader includes a first loop, a second loop, and a digital signal processor. The first loop suppresses a first transmission leakage signal of an RX signal in response to a first leakage control signal. The second loop suppresses a second transmission leakage signal of the RX signal, received through the first loop, in response to a second leakage control signal. The digital signal processor generates the first leakage control signal and the second leakage control signal. The digital signal processor generates the first leakage control signal until the level of the first transmission leakage signal becomes equal to or lower than the level of a first reference transmission leakage signal.
