You might want to consider hybrid RF modules.  I'm not sure about the
US, but the UK has parts of 418 MHz, 433 MHz, and 458 MHz allocated
for low power devices.  You can get approved modules (by the DTI in
the UK) which do not require a license.

Some of these quote a 100m range, whicle others quote 1000m.  The bit
rates vary between 2 Kbps to 10Kbps.

Hope this is of some help.

Cheers, Ian.
