THE FCC’S OFFICE OF ENGINEERING AND TECHNOLOGY RELEASES REPORT 
ON TESTS OF PROTOTYPE TV WHITE SPACE DEVICES
ET Docket No. 04-186
The Federal Communication Commission’s Office of Engineering and Technology (OET) today 
released a report entitled Evaluation of the Performance of Prototype TV-Band White Space 
Devices.  The report includes detailed results of laboratory and field interference tests of several 
prototype TV band white space devices.   The report also makes a number of general 
observations about the overall results.  
The Commission conducted laboratory and field tests of prototype white spaces devices as part 
of the above captioned rule making to consider authorizing the operation of new low power 
devices in the TV broadcast spectrum at locations where individual channels/frequencies are not 
being used for authorized services (TV white spaces) (ET Docket Nos. 04-186 and 02-380).   
The testing was open to the public.  The test plan was initially released on January 17, 2008. See

The report has been inserted into the record for the above-captioned proceeding.  Parties may
