Very impressive. I want one in my house.
I would think they could bypass the fog problems by using an ultraviolet light source. As I understand it, UV is less affected by atmospheric water vapor.
Not sure what the freq range is for UV but I suspect it is less. I believe that many places already use something similar to this but maybe not the same bandwidth. Alot of places already use a line of sight broadband for a building to building connection. The name of this I can't seem to remember off the top of my head but I know many places like GWU for instance have resorted to this when cabling wasn't always practical. Regardless cabling is still needed either way so atleast I am not out a job[:D]
Thats something I definatly want to play with!Cant imagine having access to that kind of speed!
2 words -- HOLY CRAP!
i found this cool website on free space opticswith informational videos.....check it out...http://freespaceoptics1.com
If this is a potential legitimate future alternative to broadband connections, I'm sure "line of sight" is merely just the easiest and cheapest way to transmit this laser beam. A hollow cable with a reflective inner body could easily reflect the beam at angles and/or curves throughout its transfer to maintain its contact with the receiver. Think of shining a flashlight into a flexing reflective paper towel roll. Obviously a weakened signal might arise from this, but that will depend largely on the strength of this light beam, the reflectiveness of your inner cable, the sensitivity of your "high sensitivity receiver," and obviously the distance at which the beam must travel.
