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.

摘要： According to one embodiment, a communication device includes a first wireless device configured to transmit a signal and a second wireless device configured to transmit a positive acknowledge when reception of the signal is successful. In the first wireless device, a first controller controls a first transmission module to change a first frequency channel based on a change order stored in a first storage when the positive acknowledge is not received even after the time measured by a first timer exceeds a first period. In the second wireless device, a second controller controls a second reception module to change the first frequency channel based on the change order stored in a second storage when the positive acknowledge is not transmitted even after the time measured by a second timer exceeds the first period.
