If in recent years, the data transmitted via radio waves, so in this technology the data is transmitted using light waves. Yes, radio waves are not the only electromagnetic waves that can transmit data. Light wave is also one of the electromagnetic waves that can deliver the data. Examples of application of this simple technology can be seen on the television remote, but more powerful.
Quoted from vivanews.com (21 August 2011), Harald Haas, the German physicist reveals a new solution that he calls "the data through the illumination 'or carrying out of the fiber optic fiber by sending data through LED light has an intensity that varies much faster than man who could be arrested. D-Light, Haas called for the finding, claiming that these findings could result in data transmission at speeds above 10 megabits per second which is far above the average speed of current broadband connections.
According to Haas, the future data to be transmitted to laptops, smartphones, and tablets will be transmitted through the lights in the room. And the issue about security is also so very easy. If the lights do not exist, the data can not be transmitted.
Haas argues, many things can be done using this technology. Start of public internet access via a street lamp, until the vehicle is driven automatically by headlights.
In addition, the data comes through the spectrum that could be seen as the lights can help ease fears that the electromagnetic waves that come with WiFi can damage health.
