How important is line of sight? There aren't any massive obstacles like hills or big office buildings in the way, it'd be from rooftop to rooftop, though there are a few trees and a couple of buildings in the way (though the buildings are roughly the same height or not too much higher i think).
How powerful will the antennas have to be at either end? Is it even possible with a few obstacles in the way?
I took a few photos but the trees somewhat block the view so they arent much use.
I assume 5.8ghz Wireless N would help in terms of minimizing interference?
This is just an idea atm, wondering if its feasable at all.
