If you pick up apples from your side of the fence, OK, but climb that tree to get to the apples at the top, have you trespassed? If you intercept and read their mail, that is one thing. You are "listening" to their transmissions. But, when you send your Wi-Fi signal to their receiver, on their property, and use their waves crossing their property threshold, I believe you may be crossing a point there. I can look through your open gate at what is going on in your yard. As soon as I cross that property threshold into your yard, I have committed a trespass.
