Abstract

The use of wireless and networked devices is rising exponentially, making the current radio frequency spectrum overcrowded. In view of this, this paper presents an investigative analysis of using Light Fidelity (Li-Fi) as an alternative to Wireless Fidelity (Wi-Fi) in 2-dimensional and 3-dimensional image transmission. A Li-Fi transmitter and receiver circuit diagram were developed and implemented for the purpose of the transmission. A program interface for the Li-Fi circuitry was implemented using MATLAB 2016b software. The conversion of the input image was achieved using the image processing toolbox in the MATLAB software. Therefore, it can be concluded that the channel provides high security due to the fact that light rays do not penetrate walls as well as the reasonable bandwidth required to carry both compressed and uncompressed images (2D/3D). Thus, making it suitable for image transmission.
