Short summary
Free Space Optics (FSO) offers high-bandwidth, license-free communication using air or space as a medium, but transmission is significantly degraded by atmospheric conditions like fog and rain.
AI-generated from the title and abstract; the full text is not read.
Key points
- FSO systems use free space (air, outer space, vacuum) as the communication medium.
- Successful transmission requires a line-of-sight between transceivers.
- Key advantages include high bandwidth and no spectrum licensing requirements.
- Performance is negatively impacted by atmospheric conditions (rain, fog, haze) and physical obstructions.

Abstract
FSO is a communication system where free space acts as medium between transceivers and they should be in LOS for successful transmission of optical signal. Medium can be air, outer space, or vacuum. This system can be used for communication purpose in hours and in lesser economy. There are many advantages of FSO like high bandwidth and no spectrum license. The transmission in FSO is dependent on the medium because the presence of foreign elements like rain, fog, and haze, physical obstruction, scattering, and atmospheric turbulence are some of these factors. Different studies on weather conditions and techniques employed to mitigate their effect are discussed in this paper.
