my fixed WISP
Hmmm, $135K for the network? Perhaps its time to turn it into a fixed WISP, only keep nodes electrically on that are necessary to deliver the bandwidth to the fixed location (house is on service contract), and sell much faster tiers (since you won't have other random users coming and going on the network, you can very easily model traffic). Don't let clients associate with repeaters, and stop letting associations once the number of users contracted on that node have associated, also don't let 11B clients associate. Think of it as a p2p fixed microwave link rather than a LAN. I'm sure customers will $50-80 a month for 10mbit/s upload. Also sell access to the backhaul wireless links (10s-100s of mbit/s), thats another thing that seriously killed these muni wifis. The corporation behind each one promised to sell carrier/enterprise bandwidth over the wireless backhaul, I don't think a single one ever did.
