Light Fidelity that is! It is the new wireless data transmission technology made popular by Harald Haas at TED 2011. A parisian company, Oledcomm, said that they will have Li-Fi implemented devices on the consumer market next year.
Alright, Li-Fi is nothing like our current WiFI radio. Li-Fi uses light to transfer data instead of radio waves. The way it work is pretty much like your old, old phone uses the IR port to transfer data, as any obstructions in between or even slightly misalignment will have the data transfer end up in a catastrophe. Li-Fi’s light beam is pulsates to represent data in binaries. The data beam are actually visible.
Because of how this data is focused or directed to the intended recipient, this may make your data connection more secure as they will have to be in the path of the beam to intercept your visible data. Just imagine a light bulb, they will not only illuminate the environment but it also contains data!
If you are still having a hard time to imagine this, here is a video of that data in light beam in action.
What’s even more amazing about this technology is that it is faster than Wi-Fi. WAY FASTER! So far, Oledcomm claimed that it can achieve 3 Gbps in their lab and expecting to break the 10 Gbps.It is like fiber optic technology but without those fiber optic cables. Just like how Wi-Fi is without the copper cable. Well, not literally since we know that copper cables transmit electrical pulse and Wi-Fi emanates electromagnetic waves.
I can see that we can now hide data in light beams 😀 Imagine pointing that Li-Fi sensor of yours at a random light source and getting hidden data that somebody want you to find it. Soon, LED will stand for Light Emitting Data 😀
