Effect of Rainfall on Millimeter Wavelength Radio in Gough and Marion IslandsP. A. Owolawi, Thomas J. Afullo, and S. B. Malinga doi:10.2529/PIERS080906044944 Downloads: 428 Abstract:With the increasing in spectrum occupancy and demand for high bandwidth for evolution of complex radio access network, the need to explore the advantages of millimetric wave band has become imperative. The advantages of the band are: large spectrum availability, high frequency re-used potential, small antenna and equipment size. In this paper, a new-hybrid approach is used to convert rainfall from five-minute integration time to one-minute integration time for the calculation of rain attenuation. The paper also provides information on cumulative distributions, seasonal variability, and worst month of rainfall rate for the islands. Consequently, relationship between average year (AY) and average worst month (AWM) are obtained.References:1. Marcus, M. and B.
