This piece of news was written by Adam Boult for the Telegraph online newspaper on the 25th November of 2015.
Thw news is about Li-Fi, a new alternative to Wi-fi that can send data information throught the air at 1GBPs of speed, which is 100 times faster that Wi-fi. It was invented in 2011 by Professor Harald Haas of the University of Edinburgh.
The way Li-Fi works is with VLC, which stands for visible light communication. The data information travels trough light with no need of wires and through the air. In the article, the author makes a comparison with the well known fibre optic networks. The great difference between these two kinds of connections is that fibre optic networks need optic fibre wiring while Li-Fi is wireless.
Professor Harald Haas
There are a lot of projects to test this kind of connection regulated by Velmenni, mostly in industries who are looking for a faster and safer way to transmit information. An example of these industries are airlines, to improve on in-flight connectivity and others. It is also being studied for personal internet connection.
Personally, I think that this is a great progress for technology. It would change our internet connections a lot if the information we send and receive was travelling 100 faster than it is now. Not only that, but also the fact that the wiring connections would disappear after some time, because they wouldn't be needed anymore. And also, if this system works with light (like light bulbs) i wonder if we could produce the energy needed with renewable energies. On the whole, I think this is a great thing that we should all keep an eye on.
