Light-Fidelity (Li-Fi) is an emerging technology which would essentially move the Internet out of your router, and into your light fixtures. In mobility scenario, high mobility and limited bandwidth in wireless communication lead to poor quality. So in running metro trains, it is difficult to give the facility of fast Internet. A cost-effective solution is light-fidelity (Li-Fi) communication. Visible light will provide the communication and illumination, both in metro. Which consume less power compare to the existing fluorescent light sources in metro. We propose the idea of Li-Fi as a new Wi-Fi for metro and give the designing of metro saloon with minimum number of LEDs. We analyze interference and illumination with passenger position inside metro saloon and we consider the dimensions and required illumination level used by Delhi Metro Rail Corporation (DMRC) for metro train for fixing the light-emitting diode(LED) inside the metro saloon.
