I think you more or less just buy connections from bigger ISPs, so for example you get a 100 Gbps connection to one location and distribute it to your end users from there.

Most of the equipment you can buy, you can even get a lot of the needed things as a service. You just need to organize all those hardware and software things, and get the economic and legal part right too. And in the end it needs to tie together in a way, that your earnings are bigger then your expenses.

I think it’s not so different to opening a car repair shop for example. Just more nerdy.
