Re: I may be missing something
@ Mycho: Probably this will involve Satellite uplinks a couple of hundred meters from the church itself.
We have to hope not. Why introduce significant latency if a conventional SHF link from a nearby location can be engineered? (See Duncan Macdonald's post just before yours.) Admittedly even with > 500 Mb/s capability a lot of simultaneous users in our sample village would result in a reduced bandwidth to each, but using satellite links has to be the last ditch choice.
Having said that providing a link from another site can only work if that site has spare bandwidth available on its backhaul, and that may or may not be the case.
