NO! WILL YOU FREAKING READ WHAT I'VE POSTED IN THE REST OF THIS THREAD?!?!?!?!?!?!?!?!??!?So this nanobeam is meant to point to another nanobeam, which would be wired to a computer?
It goes from one nanobeam (connected to your main router in the house) and goes to a second nanobeam. The second nanobeam goes into a switch. If you plug into that switch you will then have internet access to the switch. So you therefore get AP's to connect to the switch and mount those to the trailers.
The Nanobeams are weatherproof. You'd alsop get outdoor AP's which would also be weatherproof.
However in the end because your trailers are so spread out and the area is so large, you'd probably wind up buying way more than just another nanobeam and some outdoor AP's.
