If you do go on, I'll happily link to it in the article. There's no way I could have done everything, but I could have done a better job nodding to what's missing.
Yeah, things like CDMA and some of the other multiplexing signal techniques are incredibly cool. When I discovered that CDMA is just more or less a giant XOR with a mask in signal space it blew my mind. Being able to simultaneously share a frequency at the same time is a pretty nifty thing.
