Internet connection via Led light
Radio waves are not the only part of the spectrum that can deliver data. When surfing, a good time at the coffee shop, take advantage of free wifi in the conference room, to steal internet connection next door neighbor, you are likely to experience frustration due to slow internet speeds when many devices are connected to one network.
The more users, more devices, which connect to the internet wirelessly, which clogged the airwaves will be difficult for users to get the signal strength.

However, radio waves are not the only part of the spectrum that can carry data. There is another wave that can be used to surf the Internet.
Excerpted from Good Technology, August 9, 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 to transmit data via LED lights with varying intensity which is much faster than could man was arrested.
The idea is similar to imfra red remote control. But more powerful.
Haas said the findings, which he called D-ligth, can result in data transmission at speeds above 10 megabits per second which is far above the average speed of broadband connections at this time.
According to Haas, the future of data to be transmitted to a laptop, smartphone, and the tablet will be transmitted through the light in the room. And the problem about security as well so it’s very easy. If there are no lights, no data can be transmitted.
Haas argues, many things can be done using this technology. Ranging from public Internet access through a street lamp, until the vehicle is driven automatically by headlights.
In addition, the present data that can be seen through the spectrum such as light bulbs can help allay fears that the electromagnetic waves that come with WiFi can damage health.
