Interesting, but so much left out. This quote:-

>Through some digital gymnastics that would take entirely too long to explain, suddenly my wife’s phone shoots a 279-byte information packet containing “I love you” at the speed of light in every direction, eventually fizzling into nothing after about 30 miles.

is the biggest understatement in the whole article. It omits the entire baseband!

Within the baseband, even the channel coding process itself is insanely complex, involving convolutional codes, CRCs, weird interleaving schemes... and then there's the modulation, and all the L1 signalling to support it all... I could go on.

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.

How about making collaborative article (github?), so that everyone can write his own two cents from his field he knows?
