Could be quite expensive. Where I live (40kms from Perth, WA, in a semi-rural area) we use this Motorola wireless technology, and the prices are astronomical - $80 for 3GB on peak and 5GB off peak. When we first signed up, we also had major stability issues (connection constantly dropping out, connection hijacked by a hacker for a few months, etc.), although things are looking better now.
No idea. This is a really bad ISP who seem to get nothing but complaints - they assume that all their users are really dumb, so their technical FAQ (http://oceanbroadband.net/info/faq.html) states only that they use a proprietary system from Motorola Canopy Wireless. As for the distance from the exchange, I think we are about 10kms away, but once again I'm not entirely sure.
