Is there a possibility to create a wireless point-to-point link ?
If you want something more or less weather proof, you can get microwave P2P links that run in licensed bands and you don't get any signal interference from similar nearby antennas.
Both WiFi and Microwave equipment act just like bridges and you can connect them to a switch or router.
I recently tried AT&T fixed wireless which runs over the mobile network but it seems too congested to offer high speeds so ended up back with Comcast.
