| Summary: | Dust storms are meteorological phenomena which occur for a percentage of time in
arid and semi arid areas especially at African Sahara and Middle East. Measurements at
existing microwave links have showed dust storms can potentially result in serious attenuation
in signal level especially at Ku band and higher frequencies with direct impact on
telecommunications system performance. Only a limited amount of research has been carried
out and the available data was very scarce. Few prediction models have been developed to
estimate microwave signal attenuation during the dust storm based on scattering theory and
approximation of dust properties. However, real dust storm is a complex phenomenon which is
difficult to be described by theoretical physical or mathematical models [5-6]. In this paper, an
evaluation of the existing attenuation prediction models has been done based on the measured
dust storm properties and measured attenuation in Sudan |
