This particular article was written by me, but published some place else, since I don’t own the rights to it as a ghostwriter, but here are my thoughts on this very interesting topic.
We live in a century, where technology advances in the blink of an eye. We use the wireless computer technology (Wi-Fi) everywhere we go. Wireless communications have become a utility like water and electricity. We use it in our home environment, in our business environment, or anywhere around us. Wi-Fi is the easiest, fastest and found in a lot of public areas now internet connection, but all of this is about to change! There is a new technology waiting patiently in line to make her breakthrough and this technology is called Light Fidelity or also known as Li-Fi.
Li-Fi technology is a ground-breaking light-based communication technology, which makes use of light waves instead of radio technology to deliver data, or in more simple terms, it is a Wi-Fi using light instead of radio waves. Li-Fi uses the light waves from ordinary LED light bulbs to deliver internet connectivity that is more secure, cheaper and 100 times faster than your usual broadband internet. It seems too good to be true though. This technology, as any other, has its limitations. The connectivity is sent via overhead lights, which means you won’t be able to use your Li-Fi outdoors. This leads straight to the point that Wi-Fi won’t be completely replaced, because you will need the Wi-Fi hotspots in public.
As Radwan Mah, the COO of Great News Magazine wrote in an article about it, the tech company Velmini in Estonia, is the first one to test visible light communication technology in a real-world scenario, using Li-Fi equipped LED lights. The Li-Fi lab simulations recorded speeds up to 224 Gbps! The project was invented in Scotland in 2011, by a man named Harald Haas. The idea of Haas is that the availability is big, because everywhere in a day there is light. Everywhere around us. Our smartphones also have an LED flashlight, and all of those are potential sources for high-speed data transmission. Not only that, but the entire concept of security – you have a light in your room, but no one on the other side of this room through this wall, would be able to read that data. There’s only data where there is light.
Not to get way too excited, because Li-Fi will become available in our lives after 3-4 years from now. Just like Harald Haas said: “And in the future, you will not only have 14 billion light bulbs, you may have 14 billion Li-Fis, deployed worldwide – for a cleaner, a greener, and even a brighter future!
