I’m not smart enough to figure out if this guy is right, but it seems a bit far-fetched. It’s going to be a long long time before legacy receivers can be phased out, and until then, you can’t just step on their frequency bands. Interesting, nonetheless.
“Interference is a metaphor that paints an old limitation of technology as a fact of nature.” So says David P. Reed, electrical engineer, computer scientist, and one of the architects of the Internet. If he’s right, then spectrum isn’t a resource to be divvied up like gold or parceled out like land. It’s not even a set of pipes with their capacity limited by how wide they are or an aerial highway with white lines to maintain order.
