Radio over FSO System for 5G Wireless Communication

Abstract

Radio over Free Space Optical (RoFSO) communication is a wireless communication system that uses a highly directed beam of light to transport radio frequency (RF) signals from one point to another. The never-ending demand for faster data rates has prompted researchers to concentrate their efforts on developing new types of networks (5G) that can serve a growing number of users. Integration of millimeter (mm) wave with RoFSO is proposed to handle such traffic. Extremely high-speed communication, large-scale communication, and ultra-reliable service with minimal latency are expected to be among the many advantages of the 5G RoFSO communication system. Attenuation caused by atmospheric conditions is a dominant element, which leads to a fall in the system performance. The performance of the RoFSO communication model system varies depending on the weather conditions of a certain location or area. The major goal of this simulation is to investigate the effects of different weather conditions on RoFSO and, as a result, to assess the RoFSO system’s performance under various weather circumstances. The Q Factor of the RoFSO communication model is found to be quite low during heavy rain. However, for a given weather state, increasing the power of the laser source and the receiver aperture diameter helps in enhancing the performance RoFSO.
