Internet every day becomes so necessary that hundreds of thousands of people work daily in the world for the better. Same with their distribution channels.
This is the case of Harald Haas, a British scholar from the University of Edinburgh since 2012 working on a new Internet channel to one hundred times faster than “wi FI “, this is called” li-fi “.
Wifi, also known as wireless (WLAN) today provides the ability to connect to the Internet with a speed according to the capacity of payment (bandwidth) in space including intramural closed circuit according to the power of the server.
While “li-fi” that comes from light (light), is a technology that is based on LEDs (light-emitting diode light-emitting diode, or in Spanish) that turn on and off at an impossible speed detected by the human eye. This signal would allow the user to download a nevegación or a hundred times greater than today.
In fact, it was found that this system, which is under prueba-, can be transmitted to a gigabit per second. To cite an example, you could download an entire movie in under a minute.
Of course, being even a test pilot, he has a disadvantage (although it works for your solution). Transmission wi-fi is very similar to radio waves amplitude modulated, ie, these are expanding, by allowing you somehow have a signal range that crosses walls.
While li-fi, is more upright and waves fall directly into a beam of light, so it can not pass walls by now. However, the advantage is that it could represent a significant energy savings for the world.
Another advantage is that in future all public lamps cities could pass under the same Internet protocol, which allow greater connectivity.
