An information processing apparatus includes a radio module which wirelessly transmits and receives a packet through synchronous communication to and from another apparatus and a first controller. The first controller determines whether or not the packet transmitted from the radio module has been received by another apparatus, and selects, when reception of a previously transmitted packet by the another apparatus is not confirmed, between retransmission processing for retransmitting the previously transmitted packet and non-retransmission processing for transmitting another packet instead of the previously transmitted packet depending on a content of the previously transmitted packet.

A receiver has an ID that includes three signal detection intervals (S, S, S). The three signal detection intervals (S, S, S) are detected as the receiver detects a signal consisting of a value larger than a threshold at each of the detection timings (DTto DT). The transmitter transmits four radio frames (FRto FR) such that each of the radio frames straddles the corresponding one of the detection timings (DTto DT) in the receiver.

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