Abstract
For the CCIR 14-rain climatic zones of the globe, we present a simplified hop length versus fade margin analysis with link reliability as a parameter. The analysis uses Laws-Parsons values for the a and b parameters of A(dB/Km) = a R super(b)(mm/hr), and considers the two cases of (i) limited rain-cell and (ii) "entire hop in rain". The result is a family of fade margin vs. hop length curves for various reliability objectives, obtained for each of the 14-rain zones at a frequency of 50 GHz.
