Mobile communication terminal including rfid reader and transception method thereof

Abstract

A mobile communication terminal including a Radio Frequency Identification (RFID) reader includes a base band unit to control communications, a Radio Frequency (RF) unit to transceive a signal representing voice and data communications with an external mobile communication terminal, and an RFID unit to transceive an RFID signal with a RFID transponder in a high frequency band through the RF unit. An RFID RF block may share components with the RF unit including an antenna, an antenna switch module and a high output amplifier unit to reduce circuit area consumption. The RFID signal may be transceived over a UHF band to increase an operating range of the RFID.

1 . A mobile communication terminal, comprising:
 a control unit to control the mobile communication terminal;   a radio frequency (“RF”) unit comprising an antenna, the RF unit to transceive a first signal under control of the control unit;   a radio frequency identification (“RFID”) unit to transceive a second signal with an RFID transponder under control of the control unit,   wherein the RF unit has a first position to transmit the first signal from the antenna to the control unit, and a second position to transmit the second signal from the antenna to the RFID unit, and the first position and the second position are controlled by the control unit.   
     
     
         2 . The mobile communication terminal of  claim 1 , wherein the control unit is a base band unit. 
     
     
         3 . The mobile communication terminal of  claim 1 , wherein the first signal or the second signal is transmitted and received through the antenna. 
     
     
         4 . A mobile communication terminal, comprising:
 a control unit to control the mobile communication terminal;   a radio frequency (“RF”) unit comprising:
 an antenna; 
 a path selection unit; and 
 a radio frequency identification (“RFID”) transmission selection unit; and 
   an RFID unit comprising an RFID transmission unit and an RFID receiving unit,   wherein the mobile communication terminal transceives a signal from the RF unit and a signal from the RFID unit using a cellular communication protocol through the antenna.   
     
     
         5 . The mobile communication terminal of  claim 4 , wherein the control unit is a base band unit. 
     
     
         6 . The mobile communication terminal of  claim 4 , wherein the RFID transmission unit is coupled with the RFID transmission selection unit of the RF unit. 
     
     
         7 . The mobile communication terminal of  claim 4 , wherein the RFID receiving unit is coupled with the path selection unit of the RF unit.
