12,000 (square) mile wifi!

Exactly what I wondered about, since most of the spectrum is already used and bought by companies.

And 22 Mbps isn't that much, especially when you're thinking about the amount of bursts and collisions on that range (300 microsecond delay from just the speed of light.). If you have more than, say, 10 people on that network, you'll not have that much broadband for each of them.

I think that they would be able to have quite a few different "channels," in the in-between, as well as above and below. Given that I have a channel 1500 or something on my TV, but I only have around 900 actual channels, there's a lot of space, especially in the higher regions.
