I'm not sure this is the right group, but I recently read in
Scientific American that visible or infrared light would be a better
method to use to "talk" from a wired point on a wall to a room full of
computers than current WiFi or any other radio-wave solution. The
article kept stating that visible or infrared light was better because
they're made up of photons which don't interfere the way that radio
waves do. Since radio waves are also photons, this seemed like an
unreasonable explanation. Does anyone have any idea what the author
was trying to say?

Not without the full article but it's been done and it fell flat on it's
arse in the 80s, 90s and probably will do so again.

If you subscribe to Scientific American Digital, you can read the
article at http://tinyurl.com/2xmdnu . It's in the July 2007 issue if
you want to find it on paper. It's named "Broadband Room Service by
Light."
