I think you are automatically linking "cellular techniques" with "telcos," 
which is logically incorrect. The reason why wireless broadband will likely be 
a cellular system is that cellular provides the high density wireless links 
with credibly high bit rates. The small cells make this feasible.

And those fixed locations would also be served by cellular techniques, although 
in rural areas, the cells can be larger than in urban environments.

A matter of perspective. Femtocells are an intrinsic part of the cellular 
network. They take traffic off the outdoor macrocell and move it to a smaller 
(usually for indoor use) femtocell. But ultimately, all of these techniques 
move traffic onto a wired network, whether they be large or tiny cells, or the 
functionally equivalent WiFi local nets. So technically, all of these wireless 
techniques do exactly the same thing.
