That's what I've been trying to figure out as well. The use case of 
seamless handoff across large regions is fairly niche imo. Sure that was 
the original motivation for cell phones, but smartphones are about as 
statically located as laptops and nobody is rushing to get their laptops 
seamless handoff capabilites. That handoff capability comes at a 
tremendous cost in both spectrum and coverage.

Since everybody has their own wifi it seems that federating all of them 
for pretty good coverage by a provider and charging a nominal fee to 
manage it would suit a lot of people needs. It doesn't need expensive 
spectrum and the real estate is "free". Basically a federation of 
"guestnets".
