Re: AT&T is in for a rude awakening.. AT&T and Verizon are buying up spectrum... with wires, it's at least possible to run new ones, but you can't create a wireless service without spectrum. Lightsquared was going to lease a bunch of spectrum to new competitors, but they took a huge risk on cheap near-GPS spectrum and got burned.
Google tried to get conditions attached to new spectrum leases by bluffing $5 billion dollars, but that only goes so far when Powell was the chairman.
You could build out the wireless without buying the spectrum. You could even do what Clear did before, and lease it. If you know what you're doing a wireless network would work in most cities.
