Thanks for this article. I have been considering the feasibility of starting a WISP here in West Texas, so it's cool to see the beggining stages from the inside perspective. I whish I knew more about the laws on common access to equipment/lines. For example, the only cable provider locally is Suddenlink, AT&T Uverse is still on copper phone lines, and there is only one local ISP bringing fiber to residential customer…
Read about ILECs/CLECs. Understand what the cable offerings' contention model is.
Do the math.
Understand the support burdens of NAT-on-NAT.
Run the numbers of RF contention, and shared-medium bandwidth management.
Do the math.
Probably the best advice I could give here: It's very easy to do a mediocre job of all this. It's a fair bit harder to do a good job of it. And think of how much you dislike the mediocre ISPs.
