Li-Fi :
LiFi is a wireless optical networking technology comprises of light-emitting diodes (LED's) for data transmission.LiFi is designed to use LED light bulbs similar to those currently in use in many energy-conscious homes and offices. ... Benefits of LiFi: Higher speeds than Wi-Fi. 10000 times the frequency spectrum of radio.

What is the difference between Lifi and WIFI?
We know that Li-Fi is the short form of Light Fidelity and Wi-Fi is the short form of Wireless Fidelity. LiFi uses light for data transmission while WiFi uses electro-magnetic waves at radio frequencies for data transmission

Summary:

I think LiFi is the future as it has a lot of Apps :

1. In traffic light.
2. In Public internet Hotspot.
3. Under Sea.

Conclusion:
The possiblities are numerous and can be explored further. I think if this technology can be put into practical use, every bulb can be used something like Wifi-Hotspot for the transmission of wireless Data.
