Yeesh, I didn’t even know there were consumer grade WiFi transceivers that were strong enough to cover such a massive area. Was it a small farm or just a big property? That had to have been a pretty expensive WiFi system regardless. Did you use Ubiquiti directional access points or something?
I have a sister that runs a small family farm and she asked my brothers and me (3 of us have IT backgrounds/careers) for viable coverage solutions to their various livestock areas. We settled on just running copper to one barn from her house and broadcasting from there with a few repeaters equipped with trunk channels in order to maintain full duplex.
Not to mention using touch controls for it is brutal. At least, for me it is. Might be decent if using a controller with your phone.
