UVA Researchers to Provide Faster Data Through LED Light

CHARLOTTESVILLE, VA (NEWSPLEX) — Wireless Internet is about to be looked at in a whole new light. One professor and a few PhD students at the University of Virginia are designing a way to use light waves to get data faster. Wi-Fi uses radio waves to transfer data to devices like smart phones and computers. This new system would use a mechanism through a light emitting diode, or LED, to send light waves that would transfer data. It would ‘pulse’ quickly to send the data, something that would be invisible to the human eye. It is all starting with a prototype desk lamp that would provide an internet connection. The system would provide an Internet connection for every user individually. Maite Brand-Pearce is an electrical engineering professor at UVa and has been working on the project with some PhD students toward getting a product that is more powerful and can be used in large rooms with multiple people. “This light that’s on top of me is providing me data but the light that’s on top of you is providing you data,” said Brand-Pearce. “So we don’t compete. So while Wi-Fi is here in this building, I share it with ten offices. I’m constantly competing for bandwidth.” The new light could be used in airplanes where Internet connection is unavailable with the overhead lamp. It could also be used in hospitals where Wi-Fi is not permitted. The technology may one day be designed for large stadiums where there is competition between users. http://www.newsplex.com/home/headlines/UVa-Researchers-to-Provide-Faster-Data-Through-LED-Light-311806601.html
