We agree. The "gray area" arises from the fact that "residential" is not strictly defined. When the distinction was first made in subpart B, it hinged on whether equipment was sold for use in the home, not whether it was installed close to a home or farther away.
I take the position that the need may be defined by whether the field strength from a class A device would be above the Class B limit at or inside a residential property. Whether Class B is enough is debatable. It is certainly not enough to protect non-broadcast communications, where received signals may be less than 20 dBuV/m.
