LI-FI IT WORKS LIKE WIFI ( 100 times faster than WiFi Internet speed up to 10Gbps)

This brilliant idea was first showcased by Harald Haas from university of Edinburgh, UK, in his TED Global talk on VLC i,e visible light communication.

Future Internet:
Li-fi technology enables faster internet speed and most reliable connection. even when the demand for data usage has outgrown the available supply from technologies. Such as 4G, LTE and wifi. It will not replace these technologies, but will work seamlessly along side them.

   

Visible light communications (VLC) works by switching the current to the LEDs off and on at a very high rate.



Both Wi-Fi and Li-Fi transmit data over the electromagnetic spectrum, but whereas Wi-Fi utilizes radio waves, Li-Fi uses visible light
