Li-Fi – Light Based Wireless Technology For Internet

What is Li-Fi? Li-Fi is a bidirectional, high-speed and fully networked wireless communication technology similar to Wi-Fi. Like Wi-Fi, Li-Fi is wireless and uses similar 802.11 protocols; but it uses visible light communication (instead of radio frequency waves), which has much bigger bandwidth. How it works?
