Abstract: According to one embodiment, a storage device includes a wireless communication circuit, a storage, and a controller circuit. The wireless communication circuit is configured to connect to an external first device by wireless communication. The storage has a storage region. The controller circuit is configured to correct first information on the basis of a first capacity which is a free space of the storage region of the storage. The first information is numerical information indicating quality of the wireless communication with the first device. The controller circuit obtains second information being the corrected first information.

Abstract: According to one embodiment, a communication device includes a first interface, a wireless communication unit, and a memory unit. The memory unit includes a first region used for first access from the first interface and a second region used for second access from the wireless communication unit. Writing to the second region by the first access and writing to the first region by the second access are inhibited.

Abstract: A wireless communication method includes receiving a first frame requesting to start a registration protocol in Wi-Fi protected setup (WPS) of wireless LAN security standards, transmitting, after receiving the first frame, a second frame containing security types and encryption keys for the respective security types, and transmitting a third frame, after transmitting the second frame, the third frame instructing to terminate WPS. The security types include at least one of Wi-Fi protected access (WPA), WPA2 and WEP.

Abstract: A wireless communication equipment system which performs wireless communication among one master station and more than one slave station is configured so that each of the slave stations requests the master station to reply acknowledgement frames so as to perform transmission acknowledgement to broadcast frames or multicast frames transmitted from the master station. The master station is configured to decide order of replies of the acknowledgement frames of the slave stations which have requested the replies of the acknowledgement frames and to notify the order of the replies of the acknowledgement frames.

Abstract: When a communication is performed between an access point and a wireless terminal according to the IEEE 802.11 of a wireless LAN communication, a MAC layer block of a wireless communication apparatus used as the access point adds an identifier showing a support of aggregated transmission of a MAC layer management frame or upper layer several frames to a body of a beacon frame.

Abstract: An access point transmits data frames to a plurality of wireless terminals by MC or BC communication. When the data frames are transmitted, data to identify the presence of the return of an ACK frame as affirmative acknowledgment with respect to transmitted contents is applied to an MAC header. In a case where a Block ACK frame is requested as affirmative acknowledgment with respect to the transmission of a plurality of frames in the MC or BC communication, the plurality of wireless terminals return the Block ACK frame to the access point and the wireless terminals other than the wireless terminal itself by the MC or BC communication.

Abstract: Wireless communication is performed between an access point and a plurality of wireless terminals pursuant to standard of wireless LAN communication. The access point transmits a plurality of data frames to the plurality of wireless terminals by one communication of multicast communication and broadcast communication and designates some of the plurality of wireless terminals to return Block Acknowledgement frames as an acknowledgement response. The designated wireless terminals produce the Block Acknowledgement frames and return them to the access point when required to return the Block Acknowledgement frames from the access point.
