Li-Fi, a new way to connect the internet

Chinese scientists have connected four computers to a one-watt light bulb though technology known as Li-Fi – wireless communications sent through a light bulb opening doors for what may be a more cost efficient way of linking the country than current Wi-Fi systems.

Li-Fi could be the way we connect to each other and the Internet after four scientists have used light waves to create a networked, mobile, high-speed communication that operates in a similar manner as Wi-Fi through radio spectrum. The light bulbs, with embedded microchips, can transmit at speeds up to 150mbps, much higher than the average broadband speed in China.
Don’t expect Li-Fi light bulbs to be on sale in ALIBABA any time soon. There are significant practical barriers as signals are interrupted if the light sources are blocked in any manner.

We had envisioned numerous applications for Li-Fi ranging from car headlights transmitting data or using office lights as data transmitters.

"In the future you will not only have 14 billion (LED) light bulbs, you may also have 14 billion Li-Fi's deployed worldwide for a cleaner, greener, and even brighter future."
