Rain Rate Statistical Conversion for the Prediction of Rain Attenuation for Terrestrial Links in Bangladesh
Rain is a dominant source of attenuation at higher frequencies and consequently degrades the system performance in tropical and subtropical regions. The knowledge of rain fade and its performance is essential in order to optimize system capacity and meet quality and reliability. The rain intensity data for Bangladesh is not available since it has not been measured so far. In this paper, one-minute integration time rain intensity is derived from measured annual rainfall statistics from long term rainfall data collected from 34 meteorological stations for last thirteen years which can be used to design microwave systems in any parts of Bangladesh. The converted rain intensity data and ITU-R recommended rain intensity are compared to estimate rain fades at C, Ku and Ka-bands. The deviations are found to be small at lower frequency bands and are significantly higher at higher frequency bands.
