<P>PROBLEM TO BE SOLVED: To provide a technique for communicating with a LAN via a wireless connection. <P>SOLUTION: Whether a first short-range, high-speed, wireless communication path is available is determined, and the LAN is connected using a longer range, lower speed wireless communication path if the short-range, high-speed wireless communication path is not available. The low-range, high-speed wireless communication path is a wireless connection such as an IEEE 802.11-compliant wireless LAN, and a long-range, low-speed wireless communication mode is a cellular CDMA-type connection. Whether the first IEEE 802.11 mode is available can be determined by detecting a beacon signal, or by transmitting a probe request message and detecting a probe response message in response to the probe request, indicating the presence or availability of the short-range, high-speed wireless communication path. Alternatively, the availability of short-range, high-speed wireless communication path can be detected by simply detecting activity of the path. <P>COPYRIGHT: (C)2010,JPO&INPIT |
