摘要： According to one embodiment, a wireless communication apparatus includes a wireless unit and a control unit. The wireless unit is configured to set, for each period, a transmit state including a first period for transmitting a connection request to establish connection or a receive state including a second period for receiving a connection request and to transmit or receive a signal, both lengths of the first period and the second period being equal. The control unit is configured to control the wireless unit to operate in one of a transmit mode, a receive mode and a transceive mode. The control unit causes the wireless unit to operate in the receive mode or the transceive mode before a trigger signal is externally input, and to operate in the transmit mode if the trigger signal is input.
