| Abstract | The various advanced applications of 5G based wireless communications include autonomous self-driven cars, telemedicine, smart spaces (e.g., home, office, etc.), sensor networks, high speed trains, smart cities, and many more [9]. For such data intensive wireless communications, only radio frequency (RF) based wireless systems cannot meet the desired demands because RF band is susceptible to interference, has limited capacity, and requires a heavy license fee to use the spectrum [10]. Hence, other portions of the electromagnetic (EM) spectrum and new technologies are required to be considered for fulfilling the demands of wireless communication systems in the near future. FSO, an OWe-based optical wireless communication system, is one such alternate option. Increased bandwidth demands may be met using free space optical communication or wireless optics, which are both last mile options. The FSO transmits and receives multimedia data using an LED or LASER beam as a high data rate optical link. FSO may be installed for a quarter of the cost of fibre, but communication between the transmitter and receiver must be Line of Sight (LOS). The FSO not only has many advantages but also hampered by some atmospheric conditions, which degrades the link performance. This paper reviews the FSO link design and effect of different atmospheric condition like- fog, scintillation, turbulence, rain etc. In this research paper, the simulation based on optsim to carry out the performance investigation FSO link in investigation by varying the FSO beam divergence angle is being carried out. © 2021 IEEE. |
