Personal Space
It is fair to say that the field area covered by a Part 15 compliant radio transmission is very close to the same area normally reached by ordinary speech.
On a normal day a person is likely to be heard speaking up to 200-feet away. To be heard farther one might yell.
The Carl Blare Think Tank tends to suppose that the FCC had in mind this matching of radio space to acoustic space as measured by the "footprint" of an ordinary person's "personal space" when formulating the Part 15 Rules.
With this picture in mind we must ask... under what circumstances would it seem reasonable to extend an unlicensed signal farther than one's own "footprint".
Of course it helps to understand we are not referring to shoe-size in this proposition.
