CARD FOR WIRELESS NETWORK COMMUNICATION, DEVICE WITH INCORPORATED CARD, DEVICE FOR SUPPORTING WIRELESS NETWORK COMMUNICATION AND METHOD FOR DETECTING ACCESS POINT FOR WIRELESS NETWORK COMMUNICATION

摘要

PROBLEM TO BE SOLVED: To detect a wireless access point from a mobile computer such as a note PC, a PDA and the like without using a special device for detecting access points.

SOLUTION: The card for wireless network communication includes an access point detecting circuit which detects wireless access points via a wireless antenna. The access point detecting circuit is provided with an electric power inflow path which supplies electric power in response to a request for access point detection from a user, when the power of a device is off or suspended to which the card for wireless network communication is attached. The card for communication allows the access point detecting circuit to operate in response to power supply from the electric power inflow path. When the access point detecting circuit detects a wireless access point in response to the instruction, access point detection signals are transmitted to a detection indicator or a detection voice output device. In this way, wireless access points can be detected without starting up the above device.
