ABSTRACT

In past few years, Light-Fidelity (Li-Fi) also called Visible Light Communication (VLC) has emerged as a promising technology in the field of wireless communication. It has enabled the engineering community to envision a reliable solution to current bandwidth restrictions and open a new horizon for large capacity wireless communication. In such communication system, an optical sensor or receiver translates the data which is in the form of luminous modulation flux into an electrical signal. The receiver plays an important role in data translation. In general, the Li-Fi receivers either utilize a photovoltaic module or it based on PIN photodiode. The objective of this paper is to present a comprehensive study for implementing the visible light communication system using both photovoltaic cell and PIN diode. The paper discusses the hardware modules and implementation of VLC system. In addition, the paper also provides a comparison by using an experimental setup between the photovoltaic cell and PIN diode to receive wireless data
