An RFID interrogator device has a transmission section for transmitting a command to an RFID tag and a reception section for receiving an RF signal from the RFID tag and is configured to perform backscatter radio communication with the RFID tag. The RFID interrogator device comprises a time window setting section configured to set a time window at timing of receiving preamble data added to a head of response data transmitted from the RFID tag in response to the command, and an identifying data storage section storing preamble identifying data. The RFID interrogator device compares the data received within the time window, with preamble identifying data stored in the identifying data storage section, thereby determining whether the data received is identical to the preamble data transmitted from the RFID tag.
An RFID interrogator device which transmits a command to an RFID tag and receives response data at a sampling cycle corresponding to a transmission rate of the response data from the RFID tag, the RFID interrogator comprising:
A radio communication method for transmitting a command to an RFID tag and receiving response data at a sampling cycle corresponding to a transmission rate of the response data from the RFID tag, the method comprising:
