Estimation of FSO link availability using climatic data

Free Space Optical (FSO) communication systems are being adapted increasingly to provide high speed data transmission. The transmission performance of a free space optical link could be severely degraded due to atmospheric conditions, which causes the temporal and spatial fluctuations of light intensity. Before establishing a FSO link, the meteorological condition of the given geographical area should be studied so that a better availability can be achieved. In this paper, we present a feasibility study of FSO link for four different cities of India representing different topological conditions as a case study.
