    Abstract: Article position estimation system comprises: article movement recognition part; reference point recognition part; position information generation part; and article position estimation part. Article movement recognition part generates article movement information including time point when article is taken out by mobile body or time point when article placement is completed by mobile body. Reference point recognition part recognizes reference point and generates reference point recognition information including identification information according to recognized reference point, reference point recognition time point, and information related to recognized reference point. Position information generation part generates information related to position of mobile body at reference point recognition time point based on reference point recognition information. Article position estimation part estimates position of mobile body at the time when article is moved by using at least position of mobile body at reference point recognition time point.

    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.
