Abstract: This modern Li-Fi (Light Fidelity) technology refers to 5 G Visible Light Communication systems that use light emitting diodes in a similar way to Wi-Fi as a medium to high speed communication. In the days when the Internet is a challenging area, people are searching for Wi-Fi hotspots. In wireless networking Li-Fi or New Life data connectivity is a great alternative to Wi-Fi. Li-Fi has a speed thousand times faster than Wi-Fi and provides safety as the visible light cannot pass through the walls. These technologies have put the future of connectivity not only greener but healthier and cheaper.

Keywords:  Li-Fi, Wi-Fi, LED, D-Light (Data Light), Visible Light Communication (VLC).
