A:Answer I would test by using a WiFi tablet or phone. If you are inside the front of your pole barn and get decent signal, you could put a WiFi extender at that location to catch the signal and amplify it to the back of your barn. I have read that you need about 50% signal For this to work so keep that in mind when you are testing with a WiFi device(But I assume these have much better reception than a tablet/phone with no antenna). The other option is to get 2 WiFi extenders and place one inside your house as close to your pole barn as possible, then another inside your pole barn. Last resort is to run an Ethernet cable underground to pretty much any decent WiFi router in the center of your barn to catch all of your cameras.
