Wireless data from every light bulb: Harald Haas on TED.com
02 August 2011
The Video Presentation Duration 12:52 - highly recommended! He covers how and why it makes sense to implement using them with real-world data.

Wireless data from every light bulb: Harald Haas on TED.com
02 August 2011
What if every light bulb in the world could also transmit data? At TEDGlobal, Harald Haas demonstrates, for the first time, a device that could do exactly that. By flickering the light from a single LED, a change too quick to for the human eye to detect, he can transmit far more data than a cellular tower — and do it in a way that’s more efficient, secure and widespread. (Recorded at TEDGlobal 2011, July 2011, in Edinburgh, Scotland. Duration: 12:52.)

You can also turn the lightbulb "off" and still transmit data. (The secret is: it's not actually off! Our eyes are just really not all that sensitive.)
For super extra bonus points, this method of data transmission is extremely energy efficient, even putting aside the inherent efficiency of LEDs.

Anything that goes over cell towers now, but it'll be more secure, faster, and better coverage! Light bulbs are everywhere in homes, and even cars, cell towers are not - look at all the dead zones in the mountains! Cool huh?!

And how can we be assured that they aren't really just a bug in our house?

I can explain it to you but I can't understand it for you.

Very interesting. The only hitch I can see is that this is a line of sight technology, if something interrupts the beam of light then there is no data. Conversely, this technology could be a huge boon to clandestine users who need/want to capture information in support of Law Enforcement, National Intelligence reasons, or the black hat that wants to import or export (or both) data from a target's information systems.
It also occurs to me that the long haul technologies won't benefit from the short haul increased speeds, the bottle neck will be reversed. No longer would the last mile be the slowest.

Yes, that is both a pro (for security) and a con (limits range/application), but there has to be more to it (he mentioned semi-conduction?). I guess they won't completely erase the need for other types of wireless transmission, but they can help in certain situations very well (I liked the speaker's examples of hospitals and airplanes as being opened up for transmission - if being used on an airplane, it has to go through the cabin walls and out into space somehow, right?).
