IEEE Standards Board Passes 802.16a
papason writes "Welcome the birth of the IEEE's first wireless MAN standard for broadband wireless access in bands ranging from 2GHz to 11GHz. Yes, the same group that brought you 802.11b has brought you a real
broadband wireless access standard. See wirelessman.org for more details."
Why not offer to help them out, a small 200 seat ISP probably isn't making a whole lotta moola but if it improves YOUR speed that's all that matters :)
I'd start with a nice Linux box at the front end to handle gateway, firewall and transparent squid duties, you won't need to get overly fancy, especially if you skip the cache (although it would really be in their best interests).
For a couple G in hardware you could likely save them 25% in bandwidth at the proxy, plus you could use iptables etc. for traffic shaping, throttle using iptables or squid, etc.
I've done it, I've installed 2 headend gateways for small cable/wireless ISPs here in BC, works like a dream and it does save about 25% at the proxy. Mind you, they also have the luxury of being able to throttle users at the cable modem, so they only offer 384/128 service residentially but it beats dialup, although they also own the only dialup service in town too.
