  • Patent number: 9763202
    Abstract: To suitably perform information transfer, while suppressing interference to other terminal stations, and preventing a reduction of a transmission opportunity of other terminal stations. A terminal station estimates a distance of another terminal station (within a receivable range), from an MCS or RSSI, for example, and controls a transmission power of itself, in accordance with a value weighted with respect to distance. For example, in the case where it is estimated that a number of terminal stations with a far distance has increased, from the value weighted with respect to distance, a transmission power of itself is lowered. As a result of this, transmission by multi-hop is explicitly performed, and it is possible to suppress electric wave interference of a multi-hop destination.

    Abstract: Efficient data transfer over a public network is achieved. A terminal searching unit searches for a neighboring terminal device. A display unit displays a list of terminal devices discovered by the terminal searching unit. A terminal selecting unit selects a predetermined terminal device included in the list based on the list displayed on the display unit. A data transmission unit transmits data using the predetermined terminal device selected by the terminal selecting unit as a relay. The list of neighboring terminal devices discovered by the search is displayed and a predetermined terminal device is selected using the list and is used for relay transfer, which allows the user to easily select a predetermined terminal device to be used for the relay transfer.
