Abstract


Free Space Optical Communication (FSOC) is a communication system where free space acts as a medium between transceivers which are in a line of sight (LOS). The transmission in FSO is dependent on the presence of meteorological parameters such as rain, fog, haze, mist, physical obstruction, atmospheric turbulence etc present in the atmosphere. With recent advances and interest in Free Space Optics (FSO) for commercial deployments, a proper understanding of optical signal propagation in different atmospheric conditions has become essential, and thus arises the need to rationalize the effects of atmospheric channels on terrestrial FSO link availability. In this paper, we survey prediction methods required for the design of free space optical links based on measurement data which are unique for a particular geographical location.
