Oh yes, one big difference. If you must reuse the same set of frequencies every 10 miles rather than every 250 miles, it takes a whole lot more towers to get the job done.

You seem to have a hard time wrapping your head around the concept that the small cells of a cell network are mandated PRIMARILY by the need to support many local two-way unicast links, to provide access to the wired network infrastructure. It's an entirely different problem, Craig.

And you cannot grasp the fact that cellular can do this thanks to highly efficient spectral reuse.

You also conveniently ignore the fact that there are options between 10 miles and 250.

I have frequently noted that most markets can be covered with 4-5 transmitters on existing buildings and towers. There is no need to use the density of cellular networks - hell, there are enough radio towers out there to get the job done.
