Li-Fi (Light Fidelity) Technology

This latest Technology LI-FI describes transmission of “data through illumination” taking the fibre out of fibre optic by sending data through an LED light bulb that varies in intensity faster than the human eye can follow. It’s the same idea band behind infrared remote controls but far more powerful. 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. It envisions a future where data for laptops, smart phones, and tablets is transmitted through the light in a room. And security would be snap-if you can’t see the light, you can’t access the data.
