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.

The FCC has proposed to adopt by reference the requirements of addressing measurement procedures used in the testing of transmitters. In a Public Notice issued April 1, 2016, the FCC formally requested public comments on its decision to incorporate the requirements of ANSI C63.26-2015, “American National Standard for Compliance Testing of Transmitters Used in License Radio Services,” as part of its effort to update and modernize its rules and procedures for the authorization of radiofrequency devices.

On April 8, 2016, the FCC published guidance documents on the FCC Pre-Approval Guidance (PAG) procedure, formerly known as the Permit But Ask (PBA) procedure. provides the current list of devices that are subject to the Pre-Approval Guidance procedure and provides the Pre-Approval Guidance procedures. The changes to the Pre-Approval Guidance List v16r02 are as follows:

  • Removed requirements to submit PAG samples for UWB devices
  • Clarified EMC simultaneous transmission requirements
  • Clarified confidentiality issues
  • Removed VoLTE HAC but kept VoWiFi
  • Removed signal boosters
  • Removed UNII-1 and Wi-Fi client peer-peer applications

On April 28, 2016, the FCC reaffirmed its decision to create the innovative  in the 3550-3700 MHz (3.5 GHz) band, and took additional steps to finalize the rules. The FCC established the 3.5 GHz band as an innovation band, where it is breaking down age-old regulatory barriers to create a space for a wide variety of users to coexist by sharing spectrum.

As a result of technological innovations and a focus on spectrum sharing, the FCC was able to open up 100 MHz of spectrum previously unavailable for commercial uses, and added it to the existing commercial spectrum, resulting in a 150 MHz contiguous band。 These new rules finalize the framework for the Citizens Broadband Radio Service, providing an opportunity to leverage these new innovations in spectrum licensing and access schemes to meet the needs of a variety of users, simultaneously。

By finalizing the rules, the stage is set for the next steps, including certifying Spectrum Access System Administrators and Environmental Sensing Capability Operators, holding a future auction, and making service in this band a reality.

FCC – New Import Waiver Guidance

Posted on February 28th 2020

On February 1, 2016, the FCC published , allowing import quantity limits to be exceeded if written approval is obtained in advance from the FCC Office of Engineering and Technology (OET). The waiver request must be submitted online to the FCC well ahead of the date of importation, in order to allow for processing and approval of the waiver if qualified; the waiver request must provide details and justification of the request.

斗地主达人At the October 2015 TCBC meeting in Baltimore, Maryland, the FCC announced that SAR assessments produced by "array sensor SAR systems" will be accepted, for test cases and under named conditions, when applied to switched Diversity Antenna phones。 Diversity antenna refers to having more than one antenna in a single mobile device。 The FCC ruling applies to multiple antennas that are not transmitting simultaneously and that are fed by identical hardware。 MIMO transmissions are not covered under the ruling。  The FCC will gather experience with "array sensor SAR systems," which some industry experts hope will lead to more favorable rulings on array sensor SAR systems。
