Wireless works in a similar manner to someone using a sprinkler on their lawn (this sprinkler just happens to shoot about 400 feet in every direction). What you are doing is like putting your potted plants in the path of the water.

Yes it's a service someone else paid for. The service they paid for happens to extend WAAAY beyond their property. Your using it doesn't diminish from their ability to use it.

If you still feel bad about it, go find out who it is and ask permission. At least it's a way of meeting a new neighbor.
