LED lights may be the future of broadband
German scientists say they've created a data connection that uses light produced by lamps to encode a wireless broadband signal.
The researchers, led by Jelena Vucic of the Fraunhofer Institute for Telecommunications at the Heinrich-Hertz-Institute in Berlin, say getting a broadband connection might be as simple as turning on a lamp.
Currently, most wireless connections are achieved through a radio-frequency WiFi connection. But the scientists say WiFi has limited bandwidth, and it's unclear where to find more in the already-crowded radio spectrum. By contrast, they say visible-frequency wireless has all the bandwidth one could want.
