Abstract
In the academic Information Infrastructure, the WiFi environment is indispensable for offering of good environment of study. In this research, we propose the effective method of WiFi intensity measurement. Although some WiFi intensity measurement tool exists, by building the original system on user's viewpoint, this system can measure and estimate actual data. Moreover, when we add an access point, we will enable it to evaluate whether it is effective if we add it. For the example, the system is evaluated for the data in center for Information Infrastructure, Shizuoka University.
