  • Patent number: 7808957
    Abstract: The present invention makes it possible to expand wireless LAN areas without installing a plurality of LAN base stations or wireless LAN repeaters. A wireless LAN terminal has not only a wireless LAN terminal function to communicate with another wireless LAN base station, but also a wireless LAN base station function to communicates with a wireless LAN terminal. The wireless LAN terminal encapsulates a wireless LAN signal sent from another wireless LAN terminal and sends the encapsulated signal to the wireless LAN base station. The wireless LAN base station encapsulates a wireless LAN signal destined for a wireless LAN terminal and sends the encapsulated signal to another wireless LAN terminal.

  • Patent number: 7356342
    Abstract: This invention provides a wireless LAN base station capable of accommodating all of the client terminal stations if the number of client terminal stations wirelessly connected to the wireless LAN base station increases and capable of reducing power consumption if the number of wireless client terminal stations decreases. This wireless LAN base station includes at least two wireless LAN modules, each of which are capable of holding the wireless communication with at least one client terminal station, a section for detecting the number of client terminal stations that are being holding the wireless communication with the wireless LAN base station; and a section for changing the number of active wireless LAN modules according to the detected number of the client terminal stations.

  • Patent number: 7239890
    Abstract: A wireless communication terminal comprising antennas 4, 5 for receiving signals based on first and second wireless LAN standards, RF circuits 10, 13 for receiving the signals from the antennas 4, 5, a switch 16 for switching the standards of the signals received by the RF circuits to each other, reception level judging portions 12, 15 for judging the reception level of the signals in the RF circuits 10, 13 in the priority order from the highest standard to the lowest standard, and a controller 17 for judging on the basis of the judgment result of the reception level by the reception level judging portions whether it is possible to carry out the communications based on the first or second standard and control the switching operation of the switch so that the communications based on the standard having a higher priority can be carried out.
