A study on instantaneous degradetion of 12GHz BS link at Kagoshima

Abstract

When the climate of Kagoshima compare with some other area, it never rains but it pours through the year. I thought that it was much influence on availability of BS link. We understood rain characteristic at Kagoshima and we investigated that it was influence on availability of BS link. As a result, we could understand that 0.1% of rain time happened instantaneous degradation and availability of BS link cound not keep above 99.99% even if it use a big diameter antenna at 1993(worst year of last three years).
