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?
