Optical wireless communication (OWC) covering an ultra-wide range ofunlicensed spectrum has emerged as an extent efficient solution to mitigateconventional RF spectrum scarcity ranging from communication distances from nmto several kilometers. Free space optical (FSO) systems operating near IR (NIR)band in OWC links has received substantial attention for enormous datatransmission between fixed transceivers covering few kilometers path distancedue to high optical bandwidth and higher bit rate as well. Despite thepotential benefits of FSO technology, its widespread link reliability suffersespecially in the long-range deployment due to atmospheric turbulence, cloudinduced fading, some other environmental factors such as fog, aerosol,temperature variations, storms, heavy rain, cloud, pointing error, andscintillation. FSO has the potential to offloading massive traffic demands fromRF networks, consequently the combined application of FSO/RF and radio over FSO(RoFSO) systems is regarded as an excellent solution to support 5G and beyondfor improving the limitations of an individual system. This survey presents theoverview of several key technologies and implications of state-of-the-artcriteria in terms of spectrum reuse, classification, architecture andapplications are described for understanding FSO. This paper providesprinciple, significance, demonstration, and recent technological development ofFSO technology among different appealing optical wireless technologies. Theopportunities in the near future, the potential challenges that need to beaddressed to realize the successful deployment of FSO schemes are outlined.
