Li-Fi stands for Light-Fidelity which is a new era of wireless communication and data sharing. There is an increase in internet users exponentially, but the Radio Spectrum is congested. Moreover, the demand for wireless data double each year. This paper focuses on developing a Li-Fi based system and analyzes its performance with respect to existing technology. LI-Fi technology also introduces the LUXIM LIFI technology and describes its integration into projection display systems. Wi-Fi is great for general wireless coverage within buildings, whereas Li-Fi is ideal for high density wireless data coverage in confined areas and for relieving radio interference issues.
