Do you mean -120 dBm? How do you measure that? At what point is the
radiated power measured? How do you connect to a device to measure it?
Besides, why stop there? Why not simply make it *undetectable*? As in,
nothing known, no matter how it's connected, can detect if the system is
operating?
Well, put simply, nothing will pass such a test. A level of -120 dBm is
around the MDS for many receivers at the input terminals. I still say
that if we *insist* on a standardized limit, someone will inevitably get
screwed because you can bet your sweet bippy it won't be -120 dBm no
matter how it's measured.

How about just making it very, very low.?? -120dB at one meter from mHz
(1/100th of 1 Hertz) upward is adequate, should keep everyone, and
everything happy, and not unreasonable for equipment that shouldn't be
spewing interference anyway.
This allows for a wide range of very poor design, without negative
affects.
We have RFI because its allowed, why not flip it from "fine, within
these levels", to "knock that crap off"?
