There appears to be no available data in the United States that show what the trends have been with regard to ambient radio noise or data that show how much of the noise present is due to unlicensed intentional emitters or any other specific types of source.[1] This is no generally accepted methodology for measuring ambient noise levels and format for recording such information.[1] The UEWG believes that the absence of such data may serve to prolong the controversy on this topic and that therefore there would be tangible benefits for the FCC to cooperate with spectrum users to develop a long-term spectrum monitoring program to observe trends in ambient noise levels. Moreover, such data are necessary for implementing Spectrum Policy Task Force recommendations, most specifically the interference temperature recommendation. The UEWG believes that a well-designed multi-year program would have significant benefits and improve spectrum management in general.

SUMMARY: The Commission will consider a Notice of Inquiry and Notice of Proposed Rulemaking concerning the development and use of the interference temperature metric and for managing the transition from the current transmitter-based approach for interference management to the new interference temperature paradigm. The Commission will address interference temperature limits and procedures for assessing the interference for expanded unlicensed operation.
