Sometimes yes, sometimes no.
When you go down in density, your fixed cost per customer
really escalates and you simply can't afford to provision as
much as you'd like to. When you leave glass as a transport
mechanism, scaling isn't easy. When you don't have a wireline
to the customer prem, scaling isn't easy.
You might have a licensed backhaul going 10 - 20 miles to feed
a remote cluster of customers (be it wireless, copper, coax,
or glass as the last mile). Those are more or less limited to
about 1.5 gb/s. Spectrum availability can reduce that. You can
sometimes stack them, but again, spectrum availability would
be king in that decision.
You might have fixed wireless as the last mile. We're
starting to see platforms capable of multi-hundred megabit per
customer with a sector capacity of low gigabits, but again,
spectrum availability comes into play here. Those solutions
require line of sight (or close to it) and only go a few
miles. The systems that can penetrate foliage really cut your
per-sector capacity to around 100 megabit, shared amongst all
customers. Those are simply limitations of physics.
When you don't have the benefits of scale, the only viable
path forward in a managed setting is usage-based billing, with
some amount of included data.
