Claim:
A channel selection apparatus of a first radio frequency identification (RFID) reader within a wireless communication portable terminal, the channel selection apparatus comprising: a channel selection unit which selects a channel to read tag information stored in an RFID tag; and a channel determination unit which determines whether the selected channel is used by a second RFID reader by measuring a number of reception times of a received signal for a certain unit time period with respect to the selected channel, and if the channel determination unit determines that the selected channel is not used by the second RFID reader, determines the selected channel to be a channel to read the tag information, wherein the channel determination unit compares the number of reception times measured for the certain unit time period with a first reference value, and determines that the selected channel is not used by the second RFID reader if the number of reception times measured for the certain unit time period equals the first reference value, and, wherein if the number of reception times measured for the certain unit time period does not equal the first reference value, the channel determination unit further compares the number of reception times measured for the certain unit time period with a second reference value to determine whether the selected channel is used by the second RFID reader.
