Estimation of Rain Attenuation at C, Ka, Ku and V Bands for Satellite Links in South Africa
Despite the fact that over 20 fibre optic cable networks have been rolled out in Africa,satellite infrastructures continue to fulfil an important role in providing communication access to rural,remote and inland areas across the globe.The fast growth in telecommunications,increased demand for bandwidth,congestion in lower frequency bands and miniaturization of communication equipment have forced the designers to employ higher frequency bands such as the C(4 to 8GHz),Ka(26.5 to 40GHz),Ku(12 to 18GHz)and V(40 to 75GHz)bands.Rain is the most deleterious to signal propagation in these bands.The contribution of rain attenuation to the quality of signal in these bands,especially in the tropical and subtropical bands in which South Africa is located,needs to be studied.The aims of this paper are to estimate the magnitude of rain attenuation using the ITU-R model,carry out link performance analysis,and then propose reasonable,adequate fade margins that need to be applied for all provinces in South Africa.
