The FCC has Experimental Radio Station Licenses.
We (Robotics Insitute, CMU) have a license for our mobile robot
work that cover 2 2Watt UHF channels, a 1 Watt 2GHz microwave channel and
2 duplex 30Watt radio channels. This kind of power is more than sufficient for
a half mile or more. Pittsburgh's terrain is rougher than most so with
less hilly areas you should get pretty good distances.

You might call your local FCC field office to get the info you need 
to get such a license.
