A Survey of Wireless LAN Usage Trend in Kyoto Women s University MIYASHITA Kensuke Abstract The era of portable infomation devices has begun in the late 199s and smart devices have spreaded explosively in the late 2s. The local area networks in university campus are being developed in accordance with the trend. In Kyoto Women s University, wireless LAN service has begun in the year 21 and grows steadily into that about 15 wireless access points are deployed in the half of the campus in 214.
