I want to get the WiFi signal from the barn to a field which is about 1km away. There is a clear line of sight from the barn to the field.
I need some help with the router hardware... Un-sure if I need 2 wireless routers or 4... I think I would need Wifi grid aerials, the one I have found says from 4km - 56km, which seems a bit far!
Has anyone done this, or can point me in the right direction?
