Patent Images
1. A mobile communication terminal, comprising:
- a first transceiver that selectively transmits and receives signals;
an RFID transceiver that selectively transmits and receives signals;
a controller that halts an operation of the first transceiver while said mobile communication terminal is performing a signal communication, and activates the RFID transceiver; and
a duplexer that alternately connects an antenna to the first transceiver and the RFID transceiver,wherein the controller deactivates the RFID transceiver while the mobile communication terminal is in an idle mode, and activates the RFID transceiver for a predetermined time slot period when the mobile communication terminal is in a sleep mode.
