Chagrin,
Achievable range is subject to a great variety of variables. Since I'm not equipped to do a range test to the applicable IEEE standards, I decided it was better to not make formal claims as to range rather than to make ones that I don't have full support for.
That said, you should see range equivalent to the base XBee module, which is about 300 ft outdoors, unobstructed. Your range may vary.
