I believe another way around this might be to limit clients from connecting below a certain signal threshold. I'm hoping for at least 3-4 miles around a tower with reliable signal and a usb dongle type interface, but I don't expect all the customers to be that way.
This is all very new to me.

Agreed. Quoting Tom DeReggi: "The secret to a successful WISP is getting the highest modulations possible so they get the most capacity." IMO, this is absolutely what makes any wireless service work well. My company offers residential wireless services on 2.5GHz spectrum. We have about 4,000 residential customers. Most are indoor NLOS, but we also have a fair number of outdoor fixed LOS customers. The indoor CPE are usually at lower modulations, and are more of a drain on the BTS RF resources than an outdoor, higher modulation CPE. This is because the schedulers in our equipment utilize throughput fairness instead of temporal fairness. It takes more RF resources to service low mod customers so the available capacity fills up quicker leading to congestion, and slow service. In our experience the aggregate throughput of a BTS with a high number of lower modulation CPE is at least half (if not more) than one with a majority of high modulation CPE. We can easily service 150-200 high modulation CPE on a single BTS compared to 40-50 low modulation CPE on the same BTS before it becomes congested. Clearwire likely has a lot of low modulation CPE out there, and has tried to make up for it by adding more base stations…at considerable cost. -- Blake Covarrubias -------------------------------------------------------------------------------- WISPA Wants You!
