The assessment of the variability of rainfall characteristics in the equatorial regions is a key problem in estimating adequate fade margin due to rain attenuation in satellite communication systems. Based on one year of disdrometer data that have been collected in Kuala Lumpur, Malaysia, this paper investigates the general characteristics of the raindrop size distribution (DSD) and the dependence...
This paper presents a physically-based methodology for the prediction of the intersystem radio interference due to hydrometeor scattering. Local precipitation phenomena are modelled through a set of synthetic rain fields generated by the MultiEXCELL model, whose ensemble correctly reproduce the local rainfall statistics and rain rate spatial distribution. The coupling-by-scattering mechanism relies...
Free space optics (FSO) is getting increased popularity during last few years due to its increased power efficiency for reasonably longer distances. Moreover, it provides data rates that can cater for our future broadband telecommunication requirements besides resolving the last mile access bottleneck. But FSO links are subjected to various kinds of signal deteriorations and attenuations due to different...
Interest in free space optics (FSO) has gained enormous popularity over the last few years, mainly due to two reasons, firstly delivering data rates that can meet future broadband telecommunication requirements and secondly as an alternate technology to solve the last mile access gap. However, optical signal transmitted in free space is subjected to deterioration while propagating due to its interactions...
Free space optics (FSO) links in the troposphere are highly dependent on different atmospheric effects, which vary according to different climatic conditions. For terrestrial FSO links, fog is the most critical of all atmospheric effects causing optical signal attenuations up to 480 dB/km in dense maritime fog environments and 130 dB/km in moderate continental fog environments. In this paper a brief...
