Can't recall. It's miles I think. The Everything Xbee thread has all the info you need and if you can't find it, no one here knows more about them than @NoWon. I know it's long, but if you just go to the thread, and then go to the Edit menu of your browser, you can use Find and enter keywords for things you're looking for like "range". Makes it a lot faster to find info you need.
Oops. Sorry about that. I've update my post, but here is it too.
