According to one embodiment, a file transmission/reception device includes a communication direction managing unit and an application unit. The communication direction managing unit, in near field communication, cuts off a connection with an opposing device in a case where a conflict occurs with the opposing device, and, after being reconnected to the opposing device, switches the file transmission/reception device to any one mode of a master mode and a slave mode. The application unit performs transmission, reception, or transmission/reception of a file between the opposing device and the file transmission/reception device in the master mode or the slave mode in accordance with a mode specified by the communication direction managing unit.

File transmission/reception device and control method of file transmission/reception device

According to one embodiment, there is provided a memory system including a proximity wireless interface, a memory, and a controller. The proximity wireless interface can communicate with a correspondent device. In the memory, a file having an extension is stored. The controller specifies, if device information related to an attribution of the correspondent device is received in the proximity wireless interface from the correspondent device, at least one of an extension recognizable in the correspondent device and an extension unrecognizable therein based on the device information and that performs first transmission control according to a specified result. The first transmission control includes at least one of selectively transmitting a file having the recognizable extension from the proximity wireless interface to the correspondent device and not transmitting a file having the unrecognizable extension from the proximity wireless interface to the correspondent device.

Memory system

According to one embodiment, a power transmission and reception system includes a power transmitter and a power receiver. The power transmitter includes a power transmission module configured to wireless-transmit power to the power receiver; and a first wireless communication module configured to perform wireless communication of data frame having data with the power receiver. The power receiver includes a power reception module configured to receive the power transmitted from the power transmission module; and a second wireless communication module configured to perform wireless communication of the data frame with the first wireless communication module using the received power. The second wireless communication module is configured to perform wireless communication while the power reception module is not receiving the power.

Power transmitter, power receiver and power transmission and reception system

According to an embodiment, a wireless communication device includes a first wireless communication section, a wireless power receiving section and a wireless control section. The first wireless communication section is configured to transmit and receive a first wireless signal. The wireless power receiving section is configured to receive power by a second wireless signal. The wireless control section is configured to control the first wireless communication section according to a wireless power reception state of the wireless power receiving section. The wireless control section activates the first wireless communication section after wireless power reception by the wireless power receiving section is started.

Wireless communication device and wireless communication system

According to one embodiment, a power transmission and reception system includes a power transmitter and a power receiver. The power transmitter includes: a power transmission module configured to wireless-transmit power to the power receiver; and a first wireless communication module configured to perform wireless communication with the power receiver. The power receiver includes: a power reception module configured to receive the power transmitted from the power transmission module; and a second wireless communication module configured to perform wireless communication with the first wireless communication module using the received power. The second wireless communication module is configured to perform wireless communication while the power reception module is receiving the power.

A client terminal for conducting wireless communications with an access point apparatus having apparatus unique information. The client terminal includes: an acceptance unit that accepts entry of the apparatus unique information; a conversion unit that converts the apparatus unique information entered through the acceptance unit into temporary connection information; a temporary connection establishing unit that establishes temporary connection with the access point apparatus to acquire main connection information required for main connection with the access point apparatus based on the temporary connection information; a reception unit that receives the main connection information from the access point apparatus; and a main connection establishing unit that establishes main connection with the access point apparatus based on the main connection information.

Client terminal having a temporary connection establishing unit

A wireless communication apparatus includes: a communication unit that communicates with a communication equipment on a wireless network; and a control unit that controls the communication unit to transmit a beacon frame of a radio signal carrying at least equipment identification information to the communication equipment and to transmit content information to the communication equipment when a connection request is received from the communication equipment.

Wireless communication apparatus and wireless communication method

In the disclosed information delivery scheme for delivering WWW information provided by information servers on the Internet to mobile computers connected to the Internet through a wireless network, a plurality of cache servers capable of caching WWW information provided by the information servers are provided in association with the wireless network. The cache servers can be managed by receiving a message indicating at least a connected location of a mobile computer in the wireless network from the mobile computer, selecting one or more cache servers located nearby the mobile computer according to the message, and controlling these one or more cache servers to cache selected WWW information selected for the mobile computer, so as to enable faster accesses to the selected WWW information by the mobile computer. Also, the cache servers can be managed by selecting one or more cache servers located within a geographic range defined for an information provider who provides WWW information from an information server, and controlling these one or more cache servers to cache selected WWW information selected for the information provider, so as to enable faster accesses to the selected WWW information by the mobile computer.
