I did a job the other day for someone who was feeding his whole village and beyond off WiFi, using his BB Sat for Uplink to the net, although I am pleased to say we got him ADSL now
I was impressed with how small the stuff on the roofs were and the range he was getting off pretty much off the shelf kit. One interesting thing he mentioned was that they weren't using a mesh style setup, this only increased overheads and they found they could the range they needed with just a couple of omni's. I think the most they needed was 2 miles, so 5 is quite amazing!
Very cool indeed, makes me wish I lived out in the sticks so I could have a play too
Cheers
Cris.
