Statistic properties of rainfall in Tokyo for millimeter-wave wireless network — Rain duration analysis

Statistic properties of rainfall in Tokyo are presented in this paper. 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 and maximum duration were 20 sec. and 335 sec., respectively. It was found that even in the campus within 1 km, rain rate is different at each site and rain rate is 40%–70 % at another site in case of strong rain.
