Light Fidelity (LI-FI)-A Comprehensive Study?

This latest technology Li-Fi (Light Fidelity) refers to 5G Visible Light Communication systems using light-emitting diodes as a medium to high-speed communication in a similar manner as Wi-Fi.Harald Haas says his invention, which he calls D-LIGHT, can produce data rates faster than 10 megabits per second, which is speedier than your average broadband connection. In the days where internet has become a major demand people are in a search for Wi-Fi hotspots. Li-Fi or New Life of data communication is a better alternative to Wi- Fi in wireless communication. Li-Fi has thousand times greater speed than Wi-Fi and provides security as the visible light is unable to penetrate through the walls, which propose a new era of wireless communication. Such technology has brought not only greener but safer and cheaper future of communication.
