I would stick to line of sight and reduce this if there are physical obstructions between the transmitter and the reciever. The denser the obstruction, the less the range.. Inverse square law and all that sort of stuff
Line of site. Obstacles in the real world: tinted glass, concrete, trees, hills, metal, wood, anything. I don't know how they can claim the outrageous range on their packages. Give a more specific real world example and I'll try to estimate your range. FRS channels are 0.5 watts, GMRS channels are 2.0 watts, but require an FCC License.
