Remote site, no infrastructure, high reliability required, etc. We started with bare rock on the side of a channel on the northern BC coast. The only viable option to survive rain fade was C band. So now you're dealing with a 2.4m dish. Operational requirements called for 3Mb of symmetrical bandwidth which needs a 40W BUC. Leads nicely into the next point; power. How are you going to feed this beast? We elected to go with 4KW diesel engines, in a redundant configuration. Don't forget shelters for all this as well. It cost around $15k just to get all of the equipment to the site. Another $13k for fuel to keep it running for 6 months. The hardware was $265k, and 3Mb from Telesat is $35k/mo.
Are there other options? Absolutely. Hughes DirecWay, XPLORnet, Shaw Direct, etc. But they're all consumer grade, unmanaged, asymmetrical, and Ku band which is highly susceptible to rain fade.
As with most things, you get what you pay for.
