Hi, Based on what the markets currently offers and what your potential customers need, you can figure out the packages that you could to sell (Internet, voip, vpn, guaranteed bandwidth...). This would give you the resources that should be considered per customer. It would also give you a hint to select the CPE (wifi, POTS, firewall...) Then, it is necessary to locate, physically the area with the greatest potential of getting customers. This would give an idea of where should the base stations be located, how many customers would be aggregated at one Base Station (having in mind how many customers will be connected concurrently) and how much downlink traffic is to be expected. In case you go for a model where the ASN-GW is centralized, all the traffic has to go from each base station to the ASN-GW. The backhauling could be done using Ethernet RF point-to-point link, re-using the mast where the Wimax antenna is. The ASN site, aggregates all the backhaul links into a switch, which then connects to the ASN-GW (BRAS like). This is where the AAA, (DHCP), DNS, NTP, NMS/EMS are also located. In my opinion, the critical point really resides on the radio part (license, authorization, legal complains, interferences...).

That's what I thought, but my friend out on the sheep farm in the next county says he gets 3Mb just like I do in the village three blocks from the CO. (Yes, he knows what he's talking about.) They must spend a lot on repeaters and concentrators.
