We all thought that when Wi-Fi came around, that was going to be the end all of Internet connections. It is fast, reliable, and found in a lot of public areas now. It certainly beats being stuck at the computer just to use the Internet. But now, there is a new connection in town and that is Li-Fi, or in other words a new wireless technology that transmits high-speed data using a visible light communication. It is now being tested by scientists and they are in the stages of bringing it to the forefront of connection for Internet usage.
In the lab, the connection was achieving speeds up to 224 gigabits per second, but the people behind it, believe they can get it to be even faster in the real world. That is why they have started to take it into the field, and put it to use in certain offices and businesses in Estonia. It is not being said, that in the field, it is achieving speeds that are around 100 times faster than any Wi-Fi connection around the world. If that is not some sort of innovation for the times, than you will be hard pressed to find a better one.
The concept of Li-Fi was invented in Scotland just a little over four years ago by a man named Harald Haas. The whole idea of Li-Fi uses Visible Light Communication or VLC. This is actually a medium that works to use visible light that is between 400 and 800 terahertz. To put it simply, it works almost like a more advanced form of Morse code, transmitting the data in order to connect. In a Li-Fi connection, the light flickering is so minute, the human eye cannot pick it up, therefore it is not going to end up being a nuisance if offices or homes were to use it.
While the idea is still in the infant stages, there is a lot that would have to be done in order for it to work feasibly. Much of the infrastructure in any building would need to be changed. So instead of changing everything old to fit the new connection system, all new technology going forward would be made to accept the Li-Fi connection as they are made to accept Wi-Fi networks. It is certainly doable, and this new change in technology could certainly be seen soon enough, just a few more tweaks and a new Internet connection could be on the horizon.
