Project IEEE 802.16 Broadband Wireless Access Working Group Title Power-Law Parameters of Rain Specific Attenuation
Abstract: A fundamental quantity in the calculation of rain attenuation statistics is the specific attenuation (attenuation per unit distance). The power-law form of rain specific attenuation is very convenient and is commonly used. It is expressed as α R k ⋅ , where k and α are the power-law parameters, and R is the rain rate in mm/h. Limited number of power-law parameters were available in the technical literature for certain raindrop size distributions. Some of these parameters had reservations for rain-rate ranges. New power-law parameters for four different (gamma, lognormal, Laws and Parsons, and Marshall and Palmer) raindrop size distributions are made. For a rain temperature of 0 C, k and α with polarization dependence are presented here for rain rates from 0 to 150 mm/h over the frequency range of 100 5 − GHz.
