That depends in part on the amount of data being sent.  Hence on the image 
resolution,
number of frames per second, and data compression.

Range is a function of transmitter power, receiver sensitivity, and 
wavelength.  In the US amateur television has far greater operational range 
than wireless webcam, but requires the operator to have an FCC license.

All, next amateur radio Field Day, why not visit with your local amateur 
radio club and see what they're doing?
