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.

You're assuming that an uncapped service is viable to offer. In many areas, it is. In many areas, it is not. 



It is viable for mobile services, even though I think mobile operators have taken the model a little too far. 

But for fixed line services, it is mainly used to print free money, or limit investment in the network. I'm okay with 
either model an operator chooses to take, because until someone else comes along to break capped services on fixed 
line, there isn't much anyone can do about it.
