Typical range between devices is about a mile if they're both on the ground or very near it. If there's a router up on a tower, your device can be significantly farther away from it. Here in my area, for example, before our router died about a week ago, it was 200 feet up on a tower, and another person with a node had their solar node up 30 feet on a flagpole, and they were 17 miles apart and able to communicate.
