Background/Objectives: Light Fidelity is popularly known as Li-Fi. This is a most recent technology that was driven by German physicist Harald Haas (1) in 2011. The technology was proposed during a global talk on Technology Entertainment Design on VLC communications. Visible light communications are optical ways of communication that network the LED for data transmission. The term Li-Fi uses VLC communication for the high-end communication that can be an alternative to Wi-Fi. The proposal of Harald Haas is comparable with IEEE 802.15.7 that is the fully dual directional and networked standard built for 802.11. Li-Fi applications are featured for their comparison with other technologies like Wireless fidelity and their general use for LAN. Materials and methods: However, the optimality of the proposed Li-Fi is within highly dense areas where Wi-Fi faces interfaces and radio interferences are no good for complimentary performance goals of the communication standard. Li-Fi proves to be better in bandwidth, connectivity and secure when the higher speeds above 1Gbps are achieved. Finding/novelty : This study outlines the characteristics of Li-Fi and describes its potential use in a smart traffic net. The smart traffic net is the future of the transport system that is based on Li-Fi. Therefore, this is called Li-Net in this article. Li-Net is a modified VaNet that uses Li-Fi for V2V and V2I communication. The leveraging of Low cost LEDs and other lighting units have lots of opportunities that can help the Li-Fi to get over Wi-Fi.
