Standard Antenna Connectors for Intentional Radiators

Question: Under what conditions does the FCC allow standard antenna connectors under Part 15.203?

Answer: Under , the FCC allows the use of standard antenna connectors only when the device requires professional installation.

斗地主达人In all other cases, intentional radiators must be designed with a permanently attached antenna(s) or a unique antenna connector that ensures that only the antenna(s) certified and furnished by the grantee can be used. An example would be a wireless local area network, typically user-installed, and therefore requires a unique connector.

If professional installation is optional, the FCC does not allow the use of a standard antenna connector. When professional installation is required, the certification grant includes this condition.

斗地主达人An applicant must clearly demonstrate the requirement for professional installation by providing to the satisfaction of the FCC the following information about the device:

  1. intended use
  2. installation requirements
  3. marketing methods

The FCC has permitted standard connectors on intentional radiators in the following situations:

  • Point-to-point applications require a tower-mounted, directional antenna.  The device is advertised in special trade publications and/or demonstrated at targeted trade shows.  The applicant satisfied the 3 information requirements listed above to demonstrate the need for professional installation.  
  • Data and control signal transmitters located in oil fields; 
  • Transmitters mounted on trains and in train stations; 
  • Pole–mounted transmitters used by utility companies; 
  • Transmitters mounted on traffic signals for use by police and/or emergency vehicles.

Standalone Module without RF Shield

Question: We have a module that does not include a RF shield, however we meet the standalone requirement for a module with a RF shield. Can we qualify for FCC certification as a standalone module?

Answer: No you cannot. To qualify as a standalone module, the RF (radio frequency) circuitry must be shielded, even if the module meets the limits in a standalone configuration without it. The RF section of the module must be shielded to help prevent RF coupling when the module is installed in a host, so it’s not enough for it to meet only the limits of the standalone configuration.

The shielding design must fully enfold all the RF circuitry, including the top, all sides, and the bottom, which may be a shielding ground plane。 The shielding must be made of sheet metal, metal mesh, or a metallic ink-coated material expressly designed as an effective shield。 Any holes in the shield must be significantly smaller than the wavelength of the radiation that is being blocked, to effectively approximate an unbroken conducting surface。

The other module circuitry, i.e. flash memory, temperature sensor, input voltage regulators, input data buffering circuits, etc. may not be RF circuitry, and therefore do not need to be shielded. However, the onus is on the grantee to employ sound engineering judgment to reduce/eliminate any possible RF coupling that might affect a host interface.


Correct FCC Attenuation Factor

Question:斗地主达人 We are testing a Part 18 consumer industrial scientific medical device. How do we apply the correct FCC distance attenuation factor?

Answer: Per (note 2), if a sufficient number of measurements are made at varying distances from the Equipment Under Test (EUT) so that the actual distance attenuation may be calculated, then that calculated factor may be applied to the level of the emissions measured at a distance closer than the specified limit distance.

While a single measurement may use a factor which could be 20 dB per decade, multiple measurements could produce for example 50 or 60 dB per decade, a significant advantage over a single measurement。

Obviously, if the emission is compliant assuming 20 dB per decade, then only the single 10 m measurement needs to be made。

Note: At these low frequencies, an approved site is not required for measurements. You may make measurements at distances greater than 10 m if:

  1. there is no ground screen on the test site,
  2. site attenuation is not measured at these greater distances,
  3. the test site area is clear of obstructions.

Requirements for Refurbished Computer Equipment

Question: If the original FCC ID is viewable on computer equipment refurbished by our company, do we need to retest it to the conducted and radiated emissions requirements of Part 15 before we sell it?

Answer:斗地主达人 No retesting or permissive change applications are required if the equipment is restored to the operational characteristics of the original certified product using the same or comparable parts, i.e. the same basic semiconductor lineup, filtering, clock circuits, etc.

However, if the refurbishment improves the computer equipment beyond its certified operational characteristics, or uses different parts that are not comparable, your company should retest to confirm continued compliance with the FCC rules and regulations。 The test results will dictate one of the following:

  • No action required
  • Prepare Class I Permissive Change report for archiving
  • Prepare Class II Permissive Change report and submit Class II Permissive Change application
  • Prepare a New Certification report and submit with supporting documentation to obtain a new FCC ID

Argentina - New Low Power Device Standard Published

On July 14, 2016, Argentina’s regulator, ENACOM (Ente Nacional de Comunicaciones), published Q2-60.14V16.1 for low power devices (superseding prior technical standard Q2-60.14V12.1).

ENACOM has offered a 180 day grace period from the date of publication whereby Q2-60.14V12.1 test reports will continue to be accepted. Once the grace period has ended, reports to the new standard Q2-60.14V16.1 must be submitted for both new and renewal Type Approval applications.

Significant changes in this new technical standard are:

  1. Number of samples required for local testing has been reduced.
    1. Devices transmitting on a single channel on the new standard Q2-60.14V16.1 require one sample.
    2. Devices transmitting on multiple channels on the new standard Q2-60.14V16.1 require one sample as long as the channel can be adjusted in the test SW of a single sample. If not, it is required to provide one sample each for low, middle, and top channels.
  2. Modular Approval is now acceptable and is sufficient for host devices. That is to say, a host device containing an Approved Low Power module does not need its own Type Approval certificate. In the case where Type Approval is being sought for the module, local testing must be carried out on the module itself*.
  3. Under Q2-60.14V16.1, local testing on the low power module can be performed if testing on the host is not possible due to product dimensions.

* Please note that where Modular Approval is being leveraged for host devices, manufacturers must ensure compliance with the technical requirements and field emission limits for the published standard。

Canada - ICES-003 Revised

斗地主达人During June 2016, Canada’s Innovation, Science and Economic Development Canada (ISED) updated ICES-003 — Information Technology Equipment (Including Digital Apparatus) — Limits and Methods of Measurement, to Issue 6. This will come into force upon its publication on the Industry Canada website at www.ic.gc.ca/spectrum. Following its publication, a transition period of three months will be provided, during which compliance with ICES-003 Issue 5 or Issue 6 will be accepted. Only compliance with ICES-003 Issue 6 will be accepted after the transition period.

Changes Include:

  • Clarification of the definition of an ITE device;
  • Inclusion of storage media;
  • Clarification of applicability of broadcasting equipment;
  • Update to reference the latest version of ANSI C63.4-2014;
  • Update to clarify that external thermostats are subject to the requirements of ICES-003.

Note: Industry will have until March 1, 2017 to ensure that these thermostats sold, offered for sale, manufactured, imported, distributed or leased are compliant。

Mexico - New Logo Standard

Mexico’s Secretaria de Economía (SE Mexico) recently issued the Draft Mexican Official Standard PROY-NOM-106-SCFI-2016。 In Mexico, products must be compliant with the Federal Law on Metrology and Standardization to be able to be imported/commercialized products in Mexico。 There are two types of standards, Official Mexican Standards (NOM) and voluntary Mexican standards (NMX)。 The new logo standard will be enforced in the near future。

Proposed new regulation:

  • A change in the dimensions of the letter, “M”, in the NOM logo
  • If a product complies with a voluntary standard, it may now have the NMX logo.
  • If the product complies with both official and voluntary standards, then it suggests the use of two logos, NOM and NMX, instead of just the NOM logo.

Eurasian Customs Union – Draft Approval for Hazardous Substances Restrictions

On August 2, 2016, the European Eurasian Commission approved the draft of Technical Regulation, “On Restriction of Hazardous Substances in electrical and electronic products.” This regulation establishes requirements for manufacturers of radio, electrical, and electronic products, prohibiting the content of certain hazardous substances. It has been developed in line with international practices including European Directive 2011/65/EU from June 8th, 2011. It also outlines conditions for confirmation of compliance, labeling, and operation in the Customs Union (CU) market. This new regulation will come into effect in November 2016 and will include the following products:

  • Domestic appliances;
  • Information technology equipment;
  • Telecommunications equipment;
  • Lighting equipment;
  • Electrical tools;
  • Leisure and sports equipment;
  • Vending machines.

This new regulation process is very similar to that of existing CU EMC and Safety Approval schemes:

  • Declaration scheme only will apply depending on equipment type. However, Certificates can still be issued if the equipment falls under the Certification scheme for other CU Technical Regulations.
  • A single Approval will be issued covering all applicable CU Regulations for a given device.
  • All products will still be required to be labeled with the correct CU conformity mark.

Chile - Additional Requirements for Supplementary Test Reports

斗地主达人Per Resolución 755, Chile’s Regulator, Subsecretaría de Telecomunicaciones (SUBTEL), has introduced additional requirements for supplementary test reports issued in cases where the test reports indicate greater output powers than allowed. In addition to showing compliance to the Chilean limits, manufacturers are encouraged to consider the following requirements in the supplementary test report:

  • For any devices operating in WLAN 5 GHz bands, the supplementary test report must clearly display that the 5500-5700 MHz band will be disabled.
  • The laboratory that tested to the Chilean limits must be clearly identified (name, address, country, contact telephone number) and the report must be issued on the appropriate laboratory letterhead and with their official logo.
  • The supplementary test report issued must clearly display the names and signatures of the persons responsible for carrying out the testing to Chilean limits.
  • If the supplementary test report is issued by a different laboratory than that which issued the main FCC/EU test reports, information must be provided in the supplementary report on the test conditions and support equipment used to carry out the testing to Chilean limits.

Please note that there is a risk that SUBTEL will reject all applications where the supplementary test report does not include all information outlined above, in addition to showing compliance to Chilean limits.
