The shape of broadband Internet is at its evolutionary peak and the speed at which we surf the web is at a constant rate of climb. However, if there is one aspect of the broadband that seems stationary as of now, is the wireless broadband internet. The current radio spectrum that permits the wifi hotspots is getting congested day after day and the means of creating other venues of opportunity are hard to find.
However, if you pay heed to the latest developments devised in the field of wireless Internet by Jelena Vučić of the Fraunhofer Institute for Telecommunications, Heinrich-Hertz-Institute in Germany, you would find that, there is an incredible revolution waiting to happen, that will change the way we access the web without wires. Ms. Vučić and her team of researchers in Germany have successfully encoded a wireless broadband signal into the light of an LED bulb and managed to gain incredible at the rate of 100 Mbit/s and after some upgrades, their experiment is now churning out a whopping 230 Mbit/s.
The technology involves the use of visible frequency wireless, wherein the wireless signals will be created flickering the lights of a room. One of the hurdles that the team faced during the experiment was the limited bandwidth provided by the LED bulbs used in the project. To get around this anomaly, the team separated the various spectrum of light and focused entirely on the blue part of the LED spectrum. This incredible breakthrough in the field of wireless broadband connectivity will be demonstrated during the Optical Fiber Communication Conference and Exposition/National Fiber Optic Engineers Conference (OFC/NFOEC) in San Diego from March 21-25, 2010.
