Abstract
Results of concurrent measurements of both attenuation due to rain at different frequencies on terrestrial line-of-sight paths and rain intensity measured in many countries all over the world are included i the data bank of the Study Group 3 ITU-R. These data can be accepted for the testing of various methods presented occasionally in professional journals and conferences for the calculation of rain attenuation distribution from measured rain intensity data. At TESTCOM, software was developed which can be used for choosing the best method for rain attenuation distribution calculation. Data from 62 terrestrial line-of-sight paths collected in 16 countries were used for 36 testing methods. Statistical parameters of testing procedure were calculated and encountered risks are described. The real proposal of cumulative distributions of attenuation due to rain at 19 GHz frequency band in the Czech Republic based on both the 5-year results of observation at TESTCOM and the above mentioned software is shown in detail and discussed. Rain attenuation calculation methods based on measured propagation and rain intensity data are of fundamental importance for the realistic calculation of new both the Point-to-Point and the Point-to-Multipoint systems.
