A display apparatus includes a plurality of surfaces, and a display device provided on at least one surface among the plurality of surfaces. A plurality of communication sections are arranged to correspond to at least two or more side surfaces with respect to the surface on which the display device is provided among the plurality of surfaces and configured to perform communication within a predetermined distance, each of the plurality of communication sections including different identification information. A control section is configured to perform control of the plurality of communication sections and the display device. When another display apparatus is connected to the display apparatus, the control section periodically performs time synchronization to synchronize an image displayed on the display device with an image displayed on a display device provided in the other display apparatus.

Display apparatus and display system

A radio communication method stores a plurality MAC frames for each of a plurality of destinations. The method decides the longest transmission time of transmission times needed to transmit the plurality of MAC frames to each of the plurality of destinations within a fixed period. The method generates a plurality of physical frames for the plurality of destinations to transmit them at the same time by connecting the plurality of MAC frames and adding additional information to each connected MAC frame so as to be a frame length equivalent to a transmission time equal to the longest transmission time.

Radio communication device, method, and program that calculate transmission time based on data rate

A physical frame is constructed, the physical frame including a medium access control super-frame payload which in turn includes a plurality of medium access control frames. With respect to the constructed physical frame, virtual carrier sense information is set in the plurality of medium access control frame so that a result of carrier sense is identical to another by virtual carrier sense based on the plurality of medium access control frames in the medium access control super-frame payload. The physical frame in which the virtual carrier sense information has been set is transmitted to a destined communication apparatus.

Communication apparatus, communication method, and communication system

According to an embodiment, a display block is a display apparatus including a plurality of surfaces. The display block includes a display device, a plurality of transmitting/receiving sections that perform communication within a predetermined distance, and a control section. The display device is provided on at least one surface of the plurality of surfaces. The plurality of transmitting/receiving sections are arranged to correspond to at least two or more side surfaces with respect to the surface on which the display device is provided among the plurality of surfaces. The control section performs control of the plurality of transmitting/receiving sections and the display device.

A wireless communication apparatus is connected to a wireless network, and is capable of functioning as a wireless network base station or as a wireless network terminal. The wireless apparatus comprises a connection control unit configured to, while the wireless communication apparatus functions as a wireless network base station, receive a configuration change request. In response to receiving said request, the connection control unit reconfigures the wireless communication apparatus to stop functioning as a wireless network base station and to start functioning as a wireless network terminal.

Wireless communication apparatus and user equipment

A wireless apparatus that periodically sends notification signals, including: a determining module that determines, before sending the notification signal, whether a wireless channel is being used by a wireless device; a sending module that sends the notification signal if the wireless channel is not used throughout a first period; a receiving module; a controller that controls the receiving module to be able to receive a signal until a lapse of a second period after transmission of the notification signal; and a suspending module that suspends supply of power to the receiving module if a signal is not received in the second period and the number of wireless devices that can communicate with the apparatus is zero. If the receiving module receives a signal in the second period, the controller controls the receiving module to be able to receive a signal after a lapse of the second period.

Wireless apparatus capable of reducing receiver power

Broadcast data is divided into a plurality of broadcast channels. Any of the plurality of broadcast channels is placed on a predetermined subcarrier in each of a plurality of main bands such that the placed broadcast channels differ from each other in a same frame and are consecutive in a predetermined order in a frame direction. The subcarriers are converted into a transmit RF signal and the transmit RF signal is transmitted.

Wireless communication device

According to an embodiment, a semiconductor device includes a wireless station selection unit configured to select a connection destination wireless station from among a plurality of wireless stations. The wireless station selection unit includes a power calculation processing unit, a storage unit, a table update processing unit, and a power variation range detection processing unit. The power calculation processing unit is configured to calculate power of each receiving signal from each of the wireless stations. The storage unit is configured to store a table, and the power of each receiving signal equal to or more than a predetermined threshold is recorded in the table in association with each of the wireless stations. The table update processing unit is configured to update the table at a predetermined timing interval. The power variation range detection processing unit is configured to detect a variation range of the power for each of the wireless stations with reference to the table and configured to set the wireless station in which the variation range is within a predetermined range as a priority candidate of the connection destination wireless station.
