> The FCC and the ITU agree that the DC to 60 GHz+ 
> wide-spectrum background noise floor is 
> increasing as more and more unregulated 
> electronic devices are used by more consumers in more ways every day.
> While it is true that large numbers of these

> unregulated devices have been open for so long? 
> Is this an impossible task? I believe the answer is an emphatic â??no.â??
> On June 15, 2016, the FCC Office of Engineering 
> and Technology Technical Advisory Council opened 
> a noise floor technical inquiry in the form of 
> ET Docket No. 16-191 to seek answers to the following basic questions:
> 1. Is there a noise problem?
>
> 2. Where does the problem exist? Spectrally? Spatially? Temporally?
>
> 3. Is there quantitative evidence of the overall 
> increase in the total integrated noise floor 
> across various segments of the radio frequency spectrum?
> 4. How should a noise study be performed?
>
> The most prominent responses were from the 
> American Radio Relay League, the Society of 
> Broadcast Engineers, the NAB, the National 
> Public Safety Telecommunications Council, the 
> National Electrical Manufacturers Association, 
> the State of California Governorâ??s Office of 
> Emergency Services Public Safety Communications, Verizon and AT&T.
> Unfortunately, most were anecdotal, not 
> accompanied with measured quantitative data. 
> This is largely because the responders did not 
> have the instrumentation resources nor the 
> budget to provide the quantitative evidence being sought.
> Despite the scarcity of quantitative data 
> submissions, one clear outcome of this TAC 
> technical inquiry is an unmistakable consensus 
> among the responders: A noise floor study is not only needed but overdue.
