摘要： A signal transmitted to an STA 200a from a communication device AP is also received by an STA 200b. Upon reception, the STA 200b measures an RSSI. The STA 200b then creates a state notice frame which includes the measured RSSI, and transmits it to the AP 100. In accordance with the received state notice frame, the AP 100 determines and updates a PHY rate for transmission to the STA 200b. This allows to increase the determination and update frequency of PHY rates than before, resulting in an improved possibility of coping with rapid changes in channel environments.

摘要： A relay device receives transfer data from a transfer-source terminal and transfers the received transfer data to a transfer-destination terminal via relaying performed by another relay device. When the transfer data is received, the relay device establishes a direct communication with the other relay device, if information regarding the other relay device is attached to the received transfer data. If information regarding the other relay device is not attached, then the relay device attaches information regarding itself to the transfer data and transfers the resulting transfer data to a wireless control station.

摘要： The present invention can prevent a fuzzy image, which is caused due to insufficient bandwidth when the bandwidth necessary for transmitting a content cannot be secured, to be displayed on a display device. When a relay apparatus (100) receives, from a DNS server, a DNS response packet regarding a domain name of a server which transmits a content, a condition judging section (210) in the relay apparatus (100) judges whether a required bandwidth for the content corresponding to the domain name can be secured in a communication path connecting to another relay apparatus (100). If the condition judging section (210) judges that the required bandwidth cannot be secured, a DNS modifying section (250) in the relay apparatus (100) rewrites a reply IP address included in the DNS response packet to an IP address of the relay apparatus (100).
