FIBER AND INTEGRATED OPTICS, cilt.42, sa.2, ss.53-92, 2023 (SCI-Expanded)
In this study, predictions by leading network technology com-panies and current literature on 5 G technologies have been investigated to shed a light on the foreseeable future of the developing communication systems infrastructure. Research has been carried out on the new-generation optical communi-cation infrastructure, which is developing in parallel with the requirements of 5 G and beyond mobile communication sys-tems, and optical-wireless communication (OWC), free-space optical communication (FSOC), visible-light communication (VLC), and optical-camera communication (OCC) is presented. Also, there is information about fiber-wireless (FiWi) and radio- over fiber (RoF) transmission systems and FSO system integra-tion (RoFSO), which finds use as an infrastructure component in the next-generation high-frequency communication.
