FCC

Recently, our lab was asked about the FCC frequency stability requirements for 902 - 928 MHz wireless transmitters.  We advised our client that transmitters that operate within the 902 - 928 MHz band are subject to FCC . The wireless transmitter carrier’s 20 dB bandwidth must be within the 902 - 928 MHz frequency band where operation is permitted under all conditions including modulation, frequency sweeping, hopping and stability, the frequency tolerance of the carrier, and over variation in temperature.

The frequency accuracy of your wireless transmitter carrier’s signal must be within ±0.001% of the operating frequency over a temperature variation of −20 degrees to +50 degrees C at normal supply voltage, as well as for variation in the primary supply voltage from 85% to 115% of the rated supply voltage at a temperature of 20 degrees C. If your wireless transmitter is battery operated, it must be tested using a new battery.

Our test lab had a customer inquiry this week and the question was as follows:
Does the FCC allow us to certify equipment that was initially verified? And what exactly are the differences between a verification, a certification, and a declaration of conformity (DoC)?
 
Our reply to this question is: No, you cannot.

The FCC does not allow certification for a device that is subject to verification. The difference between a verification, certification and DoC are as follows:

  • Verification - is a procedure where the manufacturer makes measurements or takes the necessary steps to insure that the equipment complies with the appropriate technical standards.  Verification attaches to all items subsequently marketed by the manufacturer or importer which are identical as defined in 47CF§2.908 to the sample tested and found acceptable by the manufacturer.  Products subject to verification are typically intended for industrial and/or commercial use.
  • Certification - is an equipment authorization issued by, or on behalf of, the FCC based on representations and test data submitted by an applicant.
  • Declaration of Conformity -  is a procedure where the responsible party as defined in 47CFR§2.909 makes measurements or takes other necessary steps to insure that the equipment complies with the appropriate technical standards.  The DoC attaches to all items subsequently marketed by the responsible party which are identical, as defined in 47CFR§2.908, to the sample tested and found acceptable by the responsible party.  Products subject to DoC are typically intended for consumer use.

On December 12, 2012, the FCC proposed to make available 100 megahertz of shared spectrum in the 3。5 GHz Band (3550-3650 MHz) using small cell and database technologies。 The Notice of Proposed Rulemaking (NPRM) broadly reflects the innovative thinking of the President’s Council of Advisors on Science and Technology (PCAST), which issued a report this summer recommending spectrum sharing and small cell use in the 3。5 GHz Band。 It also builds upon the FCC’s previous work to free up spectrum by promoting spectrum sharing and enabling innovative licensing techniques。

On November 21, 2012, FCC Chairman Julius Genachowski announced the following items will be on the tentative agenda for the next open meeting (December 12, 2012):

FCC Chairman Julius Genachowski announced that the following item will be on the tentative agenda for the next open meeting scheduled for Friday, November 30, 2012:

On October 17, 2012, the FCC adopted revised rules to enable Wireless Communications Service (WCS) licensees’ to use a total of 30 megahertz of underutilized spectrum in the 2。3 GHz band for wireless broadband services, while protecting the adjacent Satellite Digital Audio Radio Service (SDARS) operator Sirius XM Radio Inc。 (Sirius XM) against harmful interference。 This action continues the FCC’s efforts to remove the regulatory barriers that are limiting the flexible use of spectrum for broadband services。

On October 19, 2012, the Organisation for Economic Co-operation and Development (OECD) launched an online portal to give consumers, businesses and governments quick and easy access to the latest information on products recalled from the market in Australia, Canada, Europe and the United States。

On October 15, 2012, The United States Trade Representative (USTR) announced that the governments of the United States and Israel signed a Mutual Recognition Agreement (MRA) for the Conformity Assessment of Telecommunications Equipment. The intent of the MRA is to ease burdens on U.S. companies, especially smaller manufacturers, seeking to export telecommunications products to Israel, while maintaining the United States’ high technical standards and facilitating cross-border trade.
