As a US citizen my premise on any government involvement is to make it as impossible or as hard for them to regulate anything as can be. This includes EMC, immunity or any other thing. Too many fall under the idea that personal safety outweighs personal freedom. That may work in a socialist

Several issues. First, 15.123 is not the clause exempting devices it is a clause referring to labeling of digital ready devices. Clause 15.103 is for exemption of devices. So, while it may say exempt, unintentional radiator devices are still subject to 15.5 and 15.29 with ‘strong’

Actually I believe it was if it was exempt from compliance issues because of ISM under 15.103 (mistakenly referred to as 15.123. From there it went to the issue of it being a piece of test equipment that met the exemption, etc etc etc. The Class A or B came about after that discussion. But

The other issue is that, just because the FCC may consider collocated as being antennas in the same unit, does not affect the 20 cm rf exposure requirement for rf exposure in a mobile configuration. I am not, however, that the FCC only considers collocation as stated. For example,
