Li-Fi - Visible Spectrum Wireless Networking

Brian's recent article about LED lightbulb cameras reminded me of this strange relatively new networking technology, Li-Fi. Which is like WiFi but with light instead of radio waves.

Presented here only so you don't have to act surprised if you here it somewhere else, and can instantly launch into a damning critique on the spot. ;)

Here's the pitch:

pureLiFi, the home of Li-Fi, is recognised as the leader in the field – the use of the visible light spectrum instead of radio frequencies to enable wireless data communication. pureLiFi provides ubiquitous high-speed wireless access that offers substantially greater security, safety and data densities than Wi-Fi along with inherent properties that eliminate unwanted external network intrusion. In addition, the integration of illumination and data services generates a measurable reduction in both infrastructure complexity and energy consumption.

Here's the obligatory TED video:

And here's my advice to any bubble generation entrepreneurs:

Build a prototype LiFi Camera hybrid, make an amazingly shallow but slick video, kickstart it followed by some decent A Round funding, and cash out! [sarcasm]
