Abstract
A terminal device (1) frame-length-modulates an identifier of the radio apparatus (3) to generate a plurality of frames having a plurality of frame lengths, and transmits the generated plurality of frames to an access point (2) over wire or wireless communication. The access point (2) transfers the plurality of frames transmitted by the terminal device (1) to the radio apparatus (3) in the IP or MAC layer. The radio apparatus (3) detects the plurality of frame lengths of the plurality of frames received from the access point (2) and decodes the detected plurality of frame lengths to obtain an identifier. If the obtained identifier matches the identifier of the radio apparatus (3), the radio apparatus (3) transitions to active mode.
