RoFSO- Theoretical Study and Review

---

Abstract

Radio frequency (RF) communication technology is facing challenges in fulfilling the transmission medium demand of this IOTs (Internet of things) world due to exponential growth of wirelessly communicating electronic devices. Everybody and everything need some wireless spectrum to transmit information, but RF spectrum is limited. Speed of increasing data hungry devices is much more than emerging technologies trying to keep pace with growing demand for wireless channels. Free space optics (FSO) is one of such technologies working towards fulfilling spectrum demand till the last mile connectivity point in collaboration with existing RF technology. This paper presents review of basic RoFSO (Radio over Free Space Optics) link designing factors such as weather adaptive channel modelling, different techniques to compensate link attenuation factors and their possible outcomes along with their mathematical equations for different kinds of environmental attenuations.
