In reply to snoop6060:
Easy with a high gain directional antenna at each end. You do need to put some effort in to antenna pointing. Eg a TP-Link CPE210.
If it’s a high gain directional antenna at one end and a mobile phone or laptop at the other, it might work. Clear line of site and a quiet radio spectrum locally and it should. Only one way to find out. The CPE210 has a spectrum analyser to help you find a quiet channel.
Edit: If you’re mounting it outside, make sure to get the EMP / lightning protection correct. You’ll be sticking a conductive unit on a high pole somewhere and connecting it to your network and your ring main.
EMP grounding is one of those things you really want to research and get right rather than making it up as you go along. My building proximal surge unit grounds to the domestic earth, with an additional ground spike close to the unit. The power over ethernet injector and connected network switch gear is also inside a metal rack that’s grounded and with another surge device on its power feed and on the network cable to the house network. Redundancy is my friend.
