Abstract (in Japanese) (See Japanese page) 
(in English) Statistic properties of rainfall in Tokyo are presented in this report. Average rain duration as a function of rain rate is analyzed for future route switching technique to increase network availability. In case of strong rain (>100 mm/h), minimum, maximum and average durations were 20 sec., 335 sec. and 71 sec., respectively. It was found that even in the campus within 1 km, rain rate is different at each site and rain rate becomes 40 %-70 % at another site in case of strong rain. Maximum, minimum and average of non-simultaneous link down ratios become 100 %, 9 % and 65 %, respectively, for two links of 600 m with the same receive level -68 dBm.
