miriam_eWow! Here is a lovely tech piece in easy-to-read language. http://www.salon.com/tech/feature/2003/03/12/spectrum/
I already knew about frequency-hopping for radio communications (patented by screen goddess Hedy Lamarr, who seems to have been as smart as she was gorgeous), but it hadn't occurred to me that frequency-hopping, packet radio, and ultra-wide band transmission can make the radio spectrum an unlimited resource.
At the moment radio frequency bands are licensed to a few ultra-rich groups and the rest of us can only tune in to listen to radio and watch TV. If the above improvements in technology were adopted we could all use the radio spectrum to communicate freely, and much more effectively than at present.
