Radio waves are not the only part of the spectrum that can deliver data. When the surf, either while in the coffee shop, take advantage of the free wifi in the meeting room, to steal the next door neighbors internet connection, you are likely to experience frustration because of the slow speed of the internet when many devices connected to a network.
The more users, the more devices that connect wirelessly to the internet, the airwaves are clogged it difficult for users to get the signal strength.
Radio waves are not the only part of the spectrum that can carry data. There are other waves that can be used to surf the Internet.
However, radio waves are not the only part of the spectrum that can carry data. There are other waves that can be used to surf the Internet.
Excerpted from Good Technology, August 9, 2011, Harald Haas, German physicist reveals a new solution he calls "data through illumination" or take fiber out of fiber optics by sending data via LED lights with varying intensity, which is much faster than the people could be arrested.
The idea with an infrared remote control. But more powerful.
Haas says his invention, which he called D-Ligth, can result in the transmission of data at speeds above 10 megabits per second which is far above the average speed of a broadband connection at this time.
According to Haas, the future data to be transmitted to laptops, smartphones, and tablets will be transmitted through the light in the room. And about security issues also so very easy. If the light is not there, the data can not be transmitted.
Haas argues, many things can be done using this technology. Starting from the public Internet access via a street lamp, until the vehicle is driven through the automatic headlights.
In addition, the data that comes through the spectrum can be seen as light bulbs could help ease fears that the electromagnetic waves that come with WiFi can damage health.
