<P>PROBLEM TO BE SOLVED: To continue stable communication by copying with a change in communication environment real time in an RFID communication system. <P>SOLUTION: A reception radio wave strength measuring part 1e measures reception radio wave strength from a wireless tag 3, and a communication parameter adjusting part 1g determines optimum values about communication parameters, such as read data length during reading from the wireless tag 3 and write data length during writing to the wireless tag 3 with reference to a communication parameter optimum value table stored in a communication parameter optimum value storing part 1h based on the measured reception radio wave strength, and uses the determined communication parameters to communicate with the wireless tag 3. <P>COPYRIGHT: (C)2009,JPO&INPIT |
