RFID READER AND RF TRANSMISSION METHOD THEREOF |
摘要 |
A radio frequency identification reader and their wireless frequency transmission method for efficiently utilizing the frequency are provided to prevent the deterioration of a reader by communication interference due to changing transmission environment according to use area of the reader. An RFID(Radio Frequency Identification) reader selects a part of all of a plurality of channels(S135,S155). The radio frequency identification reader measures the selected channel each radio frequency power(S130). According to the measurement result, the radio frequency identification reader determines the transmission environment of the radio frequency(S170,S180). The transmission environment of the radio frequency is the multiple reader environment or the congestion reader environment.
