  • Publication number: 20100245931
    Abstract: An image transmission system including an image processing device and a communicating device which are communicable with each other through an access point in an infrastructure mode through an “m” channel, wherein upon a communication failure in the infrastructure mode, the communication mode is switched from the infrastructure mode to an ad hoc mode in which the two devices are directly communicable with each other through an “n” channel. During the communication in the ad hoc mode, the “m” channel is scanned to detect the access point at a predetermined time interval, and upon detection of the access point through the “m” channel, the communication mode is switched back to the infrastructure mode.

  • Publication number: 20100034184
    Abstract: A communication system comprises a main communication device including a first communication unit executing wireless communication by a first method (mainly for voice data communication) and a second communication unit executing wireless communication by a second method (for communication of data other than voice data at a higher transfer rate) and an auxiliary communication device (operating on a secondary battery) including first and second auxiliary communication units executing wireless communication with the first and second communication units by the first and second methods, respectively. Whether communication of data (except voice data) should be executed by the first method or by the second method is determined based on the amount of the data. When the first method is selected, the data is segmented in prescribed data units and the communication of the segmented data is executed by the first communication unit and the first auxiliary communication unit by the first method.
