Light fidelity, or Li-Fi, is a wireless communication technology that enables secure line of sight communications, efficient connectivity in RF hostile environments, ultra-high transmission data rates, dense and reliable networks for smart cities and nations. Optics and photonics have been important research areas for next-generation communication systems, with Li-Fi being one of them. Although wi-fi is excellent for general wireless coverage, Li-Fi technology is superior for high-speed data transfer in confined areas and data transfer without radio frequency interference. In comparison to Wi-fi, it allows you to connect a lot more devices and transfer data at a much faster rate. Li-Fi offers high efficiency and also a much-secured network system. In this paper, we explored the distribution of power density using Li-Fi technology, a simulation model is described. This paper presents a mathematical analysis of the simulation model to study the variation of power density with a change in height or change in angle between transmitter and receiver. We also tried to optimize the parameters for the best performance of the Trans receiver system. Along with mathematical simulation, we have also shown the data transmission through text and audio using the Proteus Design tool. We could successfully transmit and receive text signals with multiple inputs and multiple outputs (MIMO). We have also presented a prototype for successful audio transmission using Li-Fi technology.
