I would like to connect two buildings together (house/shop). They are about 400-500 feet apart. To my knowledge, this would require some pro-sumer or pro level gear to accomplish this. A directional antennae on both sides is a obvious choice, but what size/power of one do I need? What is the max speed I could accomplish? This would be a bridge type of setup. Prices seem to be all over the place when you move out of standard home gear.
Because this is dealing with potentially pro level gear, I think SF would have many more knowledgeable people in this area. This would fall under wireless bridges of close buildings or other outdoor setups.
I saw this, but it seem to be for any distance. Wireless network between buildings

And discussed on MSO: https://meta.stackexchange.com/questions/19102/is-su-the-best-place-for-this-outdoor-wireless-connection-question
EDIT: It would be very nice to have a POE type setup to eliminate having to run external power to the antennae.
