We perform a study about the necessary information communication technologies and these applied methods to realize ubiquitous informational society. In the technology that is important to realize ubiquitous informational society, there is wireless LAN. As a part of this study, we are doing research in order to realize the ubiquitous health care information system using wireless LAN which can grasp one's health condition in real-time (anytime, anywhere). Therefore, in this paper, as a new communication method for putting this system in practical use, the outdoor communication method which used effectively the leakage electromagnetic wave from the wireless LAN access point (or Router) of the setup individual possession in a residence is proposed. The effectiveness of our a new proposed method is confirmed by the experiment.
