FCC Confidentiality Requests
Question: We manufacture Ultra Wide Band (UWB) sensor devices and have proprietary information that we would like withheld from the public when we apply for FCC certification. What is the procedure to make such a request?
Answer: The FCC has published four Knowledge Database (KDB) documents on equipment authorization confidentiality which include specific information about short-term and permanent confidentiality, and we encourage you to review them:
726920 D01 Exhibit Confidentiality Table v01
726920 D02 Confidentiality Procedures Detail v02
726920 D03 Confidentiality FCC Submitted Apps v02
726920 D04 Confidentiality TCB Submitted Apps v02
The following summarizes confidentiality for pending and granted applications:
Confidentiality for Pending Application Exhibits
When you submit an application to the FCC or your Telecommunications Certification Body (TCB), all of the information pertaining to it while it is pending and under review is held confidential. During the application review process, only the applicant, the applicant’s agent (when applicable), the FCC, or the TCB, have access to the information, and the information can only be accessed using the FCC ID and the randomly generated FCC 731 Confirmation Number assigned when the 731 Form and application were submitted for review.
When the equipment application is approved and the FCC grant of authorization is issued, all exhibits will be publicly available via the FCC web site, unless confidentiality is requested for the eligible exhibit types in the manner described in the KDB documents.
If you filed your application with the FCC and requested a Deferral of the Grant of Authorization (see Records not routinely available for public inspection, ), your pending application information will not be made available to the public until your requested deferred grant date.
Confidentiality for Granted Application Exhibits
When you apply for equipment authorization, there are two types of confidentiality, short-term and permanent, that you can request for certain exhibits within the application using 47CFR §0.457(d), which protects trade secrets and , which requests that materials or information submitted to the FCC be withheld from public inspection. Short-term confidentiality allows you to prepare the marketing of your device without disclosing your proprietary information to the public prior to the actual sale date; permanent confidentiality ensures that proprietary information is never disclosed. The above link, 726920 D01 Exhibit Confidentiality Table v01, contains a confidential exhibit table that describes document requests that are accepted by the FCC for both permanent and short-term confidentiality.
If your request for confidentiality is denied, exhibits are immediately viewable on the Office of Engineering and Technology (OET) equipment authorization web site as soon as the FCC grant is issued.
If you file your application directly with the FCC, only one confidentiality fee is assessed, regardless of the number of exhibits to be held confidential, or the length of time, i.e. short-term or permanent. If you file your application with a TCB and request confidentiality, there is no fee assessed.
Question: We are a manufacturer of electric vehicle battery chargers; we are currently designing a charger for an electric vehicle battery to be used while the vehicle is parked connected to the electric power utility in a residential or commercial space. What FCC rules and regulations would apply to our product?
Answer: Electric vehicle chargers that charge their batteries while parked in a residential or commercial space connected to the electric power utility are subject to conducted and radiated emissions testing.
斗地主达人When a vehicle is moving, the FCC considers the potential for interference to be low, however when a vehicle is stationary, parked in a residential garage or driveway and connected to the electric power utility, the FCC deems the potential for conducted or radiated emissions to be high。 Thus, your electric battery charger (switching power supply), including the associated electronics (digital electronics) of the electric vehicle’s onboard charger, must adhere to the FCC’s equipment authorization procedure under Class B limits or verification procedure under Class A limits (industrial) as an unintentional radiator。
Though states in part: “A digital device utilized exclusively in any transportation vehicle including motor vehicles and aircraft”, and suggests perhaps that electric vehicle chargers are exempt from the FCC’s rules and regulations, they are not. In this case, the exemption applies to on-board digital devices that operate only when the vehicle is mobile, that is, moving on a road or highway.
It should be noted that while 47CFR§15。103(a) provides exemption for some digital devices used in vehicles and aircraft, the exemption is only from the specific technical rule part that applies to the device。 , the General condition for operation, and , Inspection by the Commission, still applies for such exempted devices, and as such, the operator of the exempted device would be required to stop operation of the device if it were found that the device causes harmful interference。
Question: We recently added a Spread Spectrum Clock (SSC) to one of our digital designs in order to reduce the amplitude of our fundamental clock and its harmonics. However, we see very little difference between the non-SSC mode and the SSC mode during radiated emissions testing. Can you give us your opinion?
Answer: If you configured the SSC properly, it should produce lower spectral peaks of the fundamental frequency and harmonics than the spectral peaks of the fundamental frequency and harmonics in the non-SSC mode when measured using a peak detector. The reduction in the level is dependent on the manufacturer of the SSC, the modulating waveform profile, the modulation rate used to modulate the fundamental clock frequency in the SSC mode, and the spreading rate style used (down-spreading, center-spreading or up-spreading).
When evaluating and configuring SSC in a design, it is important that you properly tailor the following timing parameters that are critical for your design to function properly and to see a reduction of your fundamental clock and its harmonics in the SSC mode:
Peak-to Peak jitter: The total percentage of spreading divided by the fundamental frequency.
Cycle-to cycle jitter: The variation in time per cycle, dependent on the waveform profile and modulated frequency.
Set-up and hold times: Care must be taken when configuring the SSC so that its configuration can support the digital design. Designs that require tighter tolerances in their set and hold time margins typically tend to use down-spreading SSC.
If you’re not seeing the expected results, we suggest that you contact the SSC manufacturer and seek guidance for proper SSC parameters including application notes. In the meantime, the link here, Spread Spectrum Clock (SSC) on Commercially Available Off-The-Shelf (COTS) Products & MIL-STD-461F Testing, should provide further guidance on the topic of SSC.
FCC Requirement for Antenna Calibration
Question: We recently had discussions with our test laboratory about the FCC requirement for antenna calibration. What is the FCC’s requirement for antenna calibration?
Answer: The FCC accepts antennas calibrated in accordance with ANSI C63.5-2006, American National Standard Electromagnetic Compatibility-Radiated Emission Measurements in Electromagnetic Interference (EMI) Control-Calibration of Antennas (9 kHz to 40 GHz). All test laboratories performing radiated emission measurements and Normalized Site Attenuation (NSA) measurements required by the FCC’s rules and regulations should use this standard, notwithstanding the FCC’s cross-references to multiple standards in its rules, regulations and public policy documents, namely:
- General compliance procedure
- Site Attenuation data to be taken pursuant to procedures in ANSI C63.4-2001
DA 09-2478 - Public Notice Pending future rulemaking to update its rules, the Commission stated it will accept test data for radiated emissions and NSA performed using ANSI C63.4-2009
Please click the link, 822428 D01 Antenna Calibration Procedure v01 for further information on the use of ANSI C63.5-2006 for calibration of antennas used to perform radiated emission measurements and NSA.

India –2012 SAR Requirements for Mobile Phones
On January 25, 2012, India’s Ministry of Communications and Department of Telecommunications published Memorandum No。 18-10/2OO8-IP stating that the Indian Government adopted International Commission on Non-Ionizing Radiation Protection (ICNIRP) Guidelines for mobile phones。 Additionally, India’s Inter-Ministerial Committee has additional concerns regarding the effect of EMF radiation from mobile phones and base stations。 Based on these concerns, India has adopted the following requirements for mobile phones or handsets:
SAR levels are limited to 1.6 Watt/kg, averaged over a mass of 1 gram of human tissue.
SAR levels must be listed on the device.
Compliance with relevant BIS standards is required. Must be “hands free” devices.
SAR levels must be available to the consumer at the point of sale. Additionally, SAR levels must be listed on the manufacturer’s website and also in the user manual.
Indian manufacturers must provide a Self Declaration with the SAR level.
Foreign manufacturers must provide a Self Declaration with the SAR level and this information must be verified by the appropriate authority to ensure strict compliance.
User’s manuals must contain some specific safety precautions regarding the use of the device.
The requirements as listed above are effective September 1, 2012.
Korea – New SAR Requirement
Beginning January 1, 2013, Korea’s Korea Communications Commission (KCC) will expand its existing SAR requirements (for mobile phones only) to include all radio equipment that is used within 20 cm from the human body。 This move harmonizes the Korean SAR requirements with FCC and other international standard requirements。 Low powered radio devices (below 20mW – such as WLAN, Bluetooth, Access Points, and 2。4 GHz devices) are exempt from this new requirement。
Currently, KCC’s draft SAR standard follows that of the FCC; however there is some possibility the new Korean standard will be modified to harmonize with the IEEE SAR standard rather than that of the FCC。
Dominican Republic – Acceptance of FCC Approved Devices
The Dominican Republic’s Institute of Telecommunications (INDOTEL) recently announced that Type Approval is not required for certain categories of products with existing FCC identifiers。 Products in the following categories and approved by the FCC are allowed to be imported and commercialized in the Dominican Republic without additional Type Approval requirements:
