Attenuation due to rain is primary cause of communication impairment on satelite-earth paths, especially above 10 GHz. Since heavy rain is spatially inhomogeneous, the use of two or more separate receiving sites, i.e. site diversity is an effective means of ameliorating attenuation to overcome severe rain fading in any climate. This paper present the scenario performance evaluation of MAN-based site diversity for VSAT networks in urban areas by using spatial-temporal rainfall modeling. Our simulation shows, that linking VSAT in this way will not only provide an interactive network for user, but also enable substantially higher availability than one VSAT operates in isolation during rain periods.
