Abstract: According to one embodiment, a wireless communication apparatus includes a wireless unit and a MAC processor. The wireless unit transmits a beacon via a wireless communication. The MAC processor controls a period at which the beacon is transmitted. The MAC processor includes a determination unit and a controller. The determination unit determines that a process of connection to a terminal starts upon receiving a response signal to the beacon to output a start signal upon receiving a response signal to the beacon. The controller transmits the beacon at a first period before the start signal is output and switches the period of transmission of the beacon from the first period to a second period when the start signal is output.

Abstract: According to one embodiment, device includes first unit, second unit, managing unit, and determining unit. The device is connected with terminals via a wireless line and delivers content to the terminals. The first unit performs connection process with respect to the terminal. The second unit performs communication with the external device. The managing unit identifies each of the terminals, and stores and manages terminal information representing a delivery status of the content to the each of the terminals. The determining unit determines, from among terminals in which terminal information is managed in the managing unit and to which the content has not been delivered, a terminal that is to perform the connection process through the first unit based on an estimation value of a remaining time in which each of the terminals is able to stay in a communication area connectable via the wireless line.
