Is this really what we want? Let's say AT&T decides to go the author's suggested route, and let's also pretend that I'm a paying AT&T customer. I travel to an area where AT&T is delivering their data through WiFi, but several shop owners in the same area have set up WiFi access points and have overrun the available WiFi spectrum in the area. The quality of my data connection suffers significantly, and I get upset at AT&T for providing poor service. Does anyone really think this is in AT&T's best interest? By using licensed spectrum, wireless providers gain tighter control over the engineering of their networks. Yes, it's a double-edged sword, but I don't see an opportunity for improvment by moving to unlicensed spectrum.
