800Mbps Wireless Network Made With LED Light Bulbs

Posted by CmdrTaco on from the don't-blink-or-you'll-miss-it dept.

Mark.JUK writes "German scientists working at Berlin's Fraunhofer Institute for Telecommunications have set a new world record for Visible Light Communication technology after they succeeded in using regular red, blue, green and white LED light bulbs as the basis for building a new 800Mbps capable ultrafast Wireless Local Area Network. Dr. Anagnostis Paraskevopoulos explained: 'With the aid of a special component, the modulator, we turn the LEDs off and on in very rapid succession and transfer the information as ones and zeros. The modulation of the light is imperceptible to the human eye. A simple photo diode on the laptop acts as a receiver. The diode catches the light, electronics decode the information and translate it into electrical impulses, meaning the language of the computer.' The solution, which could be installed on ceilings and would cover approximately 10 square meters, would be ideal for HD video streaming and inside Hospitals or Aircraft where traditional Wi-Fi is often banned. However visible light signals can easily be blocked, such as when a hand is passed in front of the transmitter."

    Seriously, does anyone here on Slashdot need their summary dumbed down that far?

      Have you read some of the comments on stories lately? I fear it may not be simplified enough.

      At least it's technically accurate and well-written in addition to being dumbed down. I'll take that over your average mystery summary, which is misleading (either in the name of sensationalism or promotion), contains several typos, and at least one meaningless buzzword.

    The storm has LED some to believe that it is one bit of a self-propelled message that is transferred over thousands of miles. While working on solar energy, transfer of this information goes on during the night, preventing the thread to be derailed by Slashdot's nuclear proponents.

    There is currently discussion whether the storm is a one (as seen from the side) or a zero (seen from top).

    Hey, I tried to keep bring it back on topic.

    Eventually, someone will figure out an even more private method, like some kind of wire.

    I bet they had something to read the modulator signals on the other side.. an Anti-Modulator perhaps?
    They could come up with some cool acronym for this system.. MOAMO ? noo.. i'm sure there's something better..
