Federal Communications Commission FCC 07-78
STATEMENT OF 
COMMISSIONER MICHAEL J. COPPS
CONCURRING
Re: Establishment of an Interference Temperature Metric to Quantify and Manage Interference and 
to Expand Available Unlicensed Operation in Certain Fixed, Mobile, and Satellite Frequency Bands,
Order (ET Docket No. 03-237)
I have concerns about today’s decision ending our consideration of the “interference temperature” 
concept.  As I stated when we opened this NOI and NPRM, the interference temperature method of 
managing interference holds promise in improving the Commission’s ability to carry out its statutory duty 
to encourage more efficient uses of the radio spectrum.  I believe that the record in this proceeding, as 
well as academic commentary, indicate that the Commission’s ongoing consideration of the issue would 
be useful.1  
Today’s item does not foreclose the Commission from considering interference temperature, 
either in a particular band or generally, in a future NOI or NPRM.  Accordingly, I hope that today’s 
decision does not represent the end of the Commission’s work in this important area.
