Could Luxor-hotel light deliver more bandwidth than fiber optic?

Last night I met an interesting inventor. He’s been involved in the invention of WiMAX, among many other things and is the founder and chief technical officer of CeLight.

But last night he showed me a laser system that could provide a community with much more bandwidth than even a fibre optic line (he claims his system will bring four to five times more bandwidth).

It’s not a point-to-point laser, either. Instead of aiming the laser at a sensor across the land, he saw the light at the top of the Luxor hotel and thought that is actually an interesting way to bring bandwidth to a community.

Last night he showed me how it works. A purple laser which is almost invisible to the human eye and which is inexpensive to buy (they are the lasers inside every Blu-Ray disk player — the lasers are actually purple light, the “blu” in the name is marketing) is aimed at the sky and an array of sensors reads data from the beam of light. Readable due to scattering of light due to the atmosphere. He showed me how this works: you aim a laser at the sky and everyone can see the beam. If your human eye can see it, sensors can see it too and due to some tricks can get massive amounts of bandwidth out of the laser.

I was fortunate enough to meet Isaac and here he explains how it works.

Why is this important? Because aiming a laser at the sky is a LOT cheaper than digging and laying down fiber. So, this might be how lots of areas get high-capacity backhaul capabilities. Translation: we’ll all get cheaper broadband that we’ll need to keep up with future HDTV and 3DTV.
