    摘要: A transmission terminal includes an information generation unit, a transmission unit, a delivery management unit, and a reception unit. The information generation unit generates information that is to be transmitted to a destination reception terminal. The transmission unit transmits information that the information generation unit has generated. The delivery management unit manages transmission of information. The reception unit receives information that the destination reception terminal transmits. Furthermore, the information generation unit generates or receives transmission information that is to be transmitted to the destination reception terminal and generates redundant information for the destination reception terminal to restore the transmission information. The delivery management unit causes the information generation unit to generate, and causes the transmission unit to retransmit, the redundant information when the reception unit has not received a successful reception reply from the destination reception terminal.

    摘要: An object of this invention is to avoid interfering from a radio LAN transmission unit and being interfered. This invention relates a radio transmission unit for transmitting according to a second radio transmission system which transmits/receives data signal under the same frequency band as first radio transmission system in which prior to transmitting of the data signal, a transmitting station transmits a transmission request signal while a reception station receiving this RTS sends back a reception preparation completion signal. This radio transmission unit comprises CTS transmitting means for transmitting CTS according to the first radio transmission system and a duration setting circuit for setting a duration time to be overlaid on the CTS, and prior to transmitting according to the second radio transmission system, the duration time set by the duration setting circuit is overlaid on the reception preparation completion signal according to the first radio transmission system.

    摘要: A position estimating system capable of accurately estimating the position assumed by a target terminal user based upon measurement of wireless reception signal levels of signals from a target terminal is provided. The position estimating system includes a target terminal that wirelessly transmits a position estimation request, a plurality of reference terminals disposed at specific positions which, measure the signal strength of wireless signals from the target terminal and a position estimating server that estimates the position of the target terminal based upon the reception signal levels measured in correspondence to each of the reference terminals. The reference terminals each include a reception signal level utilization OK/NG judgment unit that makes a judgment as to whether or not the reception signal level value having been measured is to be used in position estimation based upon an index indicating the level of reliability of the reception signal.
