[MaximumPC] German Scientists Create 800Mbps Wireless Network Using LEDs

If you listen to environmentalists and home building experts, the future of lighting lies in LEDs (Sorry to break it to you, CFL bulbs). But could LEDs also hold the key to the future of wireless home networking? Yeah, it sounds weird, but scientists at the Fraunhofer Institute for Telecommunications in Berlin got the bright idea to try and create a WLAN using nothing more than standard LED bulbs and "a few additional components." And you know what? It worked, and it worked well.
Shhhhh!

Crazy. There was a lot of hubbub about this a while back, but it hadn't been tested yet at that point. It was still in the hypothetical stage. Good to see some results.

In this stage you pretty much need line of sight. It said if something blocks the reception then it slows down considerably... I take this to mean that a person walking by will cripple your speed, but not kill it all together. The article also said it covered a 10m² area, so I'm guessing "no" on going through walls.

The suggestion of using this on an airplane is pretty cool, though. Put the LED in your overhead light and you have wireless without radio waves. If the plane has satellite internet, then internet for all!

So is my router (WNDR3700) is getting more annoying lights that would keep me up at night if I didn't turn it the other way? At least it's fast xD

That's actually a really good idea.

I guess hanging from a ceiling would work for a point to point line of sight system like this as something installed after the fact.. This could be interesting for some cool designs in architecture though.
