FCC Opens More 5GHz Spectrum

 

In an effort to accelerate the growth and expansion of new Wi-Fi technology, the FCC proposes to increase the available unlicensed spectrum by 35%, adding 195 MHz of additional spectrum in the 5 GHz band. This rule proposal today follows through with FCC chairman Julius Genachowski’s announcement at CES earlier this year (See Post).

The Unlicensed National Information Infrastructure band three (U-NII-3) will receive an addition 25MHz of spectrum and the rules for U-NII-3 (15.407) devices are proposed to align with those of digitally modulated devices (15.247). This will provide consistent rules across 125 MHz of spectrum. The rules propose to remove the 5.725 – 5.85 GHz band from section 15.247, and amend the U-NII band rules to maintain many of the technical rules that currently make certifying to 15.247 more attractive; however some of the more restrictive requirements of 15.407 will remain.

Summary of some of the proposed 15.247/15.407 technical changes;

• 15.247 will remove 5.725 - 5.850 GHz (devices using this band now under 15.407)
• Frequency band, 15.407 expanded from 5.825 to 5.85 GHz
• Power, 15.407 will fix limit at 1W as in 15.247 instead of lesser of 1W or 17 dBm + 10 log B
• PSD, 15.407 to use Power Spectral Density of 15.247 (possible change of measurement BW to 1 MHz)
• Emission Bandwidth, 15.407 will adopt min 6 dB bandwidth of 15.247
• Antenna Gain, 15.407 to retain 23 dBi maximum no penalty antenna gain  for point to point
• Unwanted Emissions limits of 15.407 will remain, more stringent than 15.247
• Peak to Average ratio of 13dB in 15.407 will remain, no such requirement in 15.247

The new rules are seeking comment on potential security features that will be required by manufacturers and implemented in any digitally modulated device capable of operating in the U-NII bands to prevent 3^rd parties from reprogramming devices to operate outside of the device’s certified parameters.

The proposal also notes potential “mitigation” techniques such as a database registration process combined with geo-location technology to determine whether there is a potential for interference to radar systems such as the TDWR.

There are several changes proposed to improve the reliability of “Dynamic Frequency Selection” DFS, namely lowering permitted Power Spectral Density (PSD) for lower powered devices using relaxed sensing threshold, modifying the Bin-1 radar waveform and removing the uniform channel loading requirement. The rules make clear that any device subject to DFS and that is capable of initiating a network, must have radar detection functionality and must be approved with that capability.

It is suggested that devices could operate in the new U-NII-2B band under the same technical framework specified in 15.407 for U-NII-2A and U-NII-2C opening operation up to the 475 MHz continuous band from 5.25 to 5.725 GHz. It is also noted that should the U-NII-3 band be increased to the proposed 5.85 GHz upper limit, then the same technical framework applicable to U-NII-3 could be applied to devices operating in the U-NII-4 band allowing operation across the continuous 200 MHz spectrum. The proposal seeks whether and how to integrate DFS into the new U-NII-2B and U-NII-4 bands.

It is noted that up to 12 months after adoption of any new or modified rules, devices could still be certified under the old rules. After 12 months, all new certifications for U-NII devices must be under the new rules. Up to 2 years after adoption of any new or modified rules, the FCC will permit Class II permissive changes to equipment certified prior to the 12 month transition date. At the end of the 2 year transition period, devices will not be permitted to be sold, manufactured, installed, imported or marketed in the United States unless they are certified under the new rules. It is explained that devices that are already installed or in use should be grandfathered for the life of the equipment.

The Notice of Proposed Rulemaking is set with a 45 day comment period, and a 75 day reply comment period. The changes proposed are far too numerous for this post to cover in toto, for the technical details, a link is provided in the reference section.

Major FCC rule update, FCC to stop certifying products all together

FCC proposes changes to product certification rules to leave certification activities exclusively to the Telecommunication Certification Bodies (TCB). FCC will require that all testing be at an accredited, approved lab. The new rules will also specify new standards for testing and recognition of TCBs and labs.

To sum up the proposed changes;

1. FCC will stop certifying products and rely solely on TCBs (including for items on exclusion list)
2. FCC to codify “permit-but-ask” procedures into new “pre-approval” procedure.
3. Rules will clarify TCB post-market surveillance requirements
4. Rules will specify steps that can be taken if TCB performance was found deficient.
5. Rules will reference latest ISO/IEC standards for accreditation and 2009 version of ANSI
6. Test labs will require accreditation to perform testing for certification.
7. A one year transition from publication date is proposed for certain aspects of the new rules

The FCC will stop issuing grants directly; rather they will rely on TCBs to perform all certifications. This will enable the FCC to focus on “enforcement” activities. The FCC will be better able to perform post-market surveillance and auditing random samples. TCBs will also be granted authority to dismiss equipment authorization applications under the same circumstances that the Commission currently dismisses and application. TCBs will not be able to deny an application. The current 30 day period that a TCB may rescind a grant remains however the term “rescind” will be changed to “set aside”.

The FCC intends to eliminate the TCB exclusion list (items that a TCB cannot approve) and codify the “permit-but-ask” procedures. The FCC will call the new system “pre-approval guidance” procedures. The new procedures will identify the types of devices or testing that would require a TCB to consult with the Commission prior to approval. The FCC intends to integrate the pre-approval guidance procedure with the current Equipment Authorization System (EAS). The new pre-approval procedure will retain the FCCs option to do a pre-grant sample test, similar to how product that requires Dynamic Frequency Selection (DFS) are sampled by the FCC prior to issuance of a grant.

The proposal will require that applicants send a written signed request for equipment authorization to a TCB. The proposal also requires that the applicant provide the TCB with all information required by the 731 application in writing (or digital form), including all exhibits required to process the application.

Previously the rules did not require a TCB to submit a complete copy of the certification application prior to grant; the rules will be amended to incorporate the requirement that the TCB provide the Commission with a complete copy of the application, including all required exhibits, prior to issuance of a grant or a dismissal of the application. The key here is that this will provide notice to the Commission and other TCBs concerning which applications have been dismissed.

FCC intends to clarify the rules regarding the post-market surveillance requirements of TCBs by making reference to the Knowledge database (KDB) procedure and to make clear the authority TCBs have when requesting samples from grantees. The FCC may direct a grantee to provide a sample for testing to the approving TCB if questions of compliance should arise.

FCC is seeking comment on the surveillance, specifically how to ensure that duplicates are not selected by the FCC and TCB for sampling? Should TCBs cross check one another, and if so, who bears the costs? Should grantees provide a voucher to enable the FCC to obtain a retail sample from the market?

Currently the rules provide for the revocation of TCB status, but no less corrective measures are specified. FCC proposes to modify rules to allow for lesser forms of corrective actions with warnings, communication and monitoring, also perhaps temporarily requiring that all applications from a deficient TCB go through the pre-approval procedure as sort of “probation” until confidence is regained in the TCBs abilities.

FCC proposes to modify rules to replace accreditation requirements of Guide 58 and Guide 61 with the new consolidated ISO/IEC 17011 and to replace reference to Guide 65 with ISO/IEC 17065. Consistent with 17065 the term “sub-contractor” will be replaced with “external resources”. The proposal notes that these changes will not have any significant impact because the revised guides are substantially similar to the guides currently specified in the rules.

Currently, equipment to be certificated must be tested at a lab that meets one of two criteria, the lab must have filed a description of the facilities with the Commission, or the lab has been accredited under ISO/IEC 17025 and recognized by the Commission. The FCC recognizes that accreditation is a more thorough and involved process than filing a description. The FCC notes that accreditation of a lab outside the United States is acceptable only of the lab is located in a country that has an MRA with the United States, or is accredited by an organization that is recognized by the Commission.

This is a big one, the FCC proposes to end the listing program for labs and require that all test labs performing tests for DoC or Certification be accredited, this would mean that only “Verification” testing could be performed at a non-accredited facility. The lab will still be required to compile the listing description, but only show it to the FCC or accreditation body upon request. The FCC will maintain a list of acceptable test labs, most likely similar to how it does now at https://apps.fcc.gov/oetcf/eas/reports/TestFirmSearch.cfm . It is worth noting that tests performed in countries without an MRA may no longer be acceptable for certification.

FCC proposes to require, rather than allow as an alternative, a test lab testing above 1GHz to meet the CISPR 16 validation criteria. Validation is to be confirmed no less than once every three years.

The FCC proposes acceptance of the measurement standards ANSI C63.4-2009 for unintentional radiators and C63.10-2009 for intentional radiators with the continued exception of the use of rod antenna below 30MHz, an artificial hand for holding hand held devices, and absorber clamp for radio noise power measurements as well as no relaxation of limits for transient emissions. The FCC is not proposing to incorporate CISPR 22 into the rules for measuring subject to part 15 as requested by the Information Technology Industry Council (ITI).

FCC proposes that test setup photos be included for each of the required types of tests applicable to the device for which certification is requested. The FCC also proposes that any photographs be “focused originals” without glare or dark spots, and must clearly show the test configuration used.

As for a transition period, the FCC notes that two of the changes may require some time for laboratories to meet. These are; 1) laboratories must be accredited, and 2) above 1GHz testing site validation in accordance with C63.4-2009. The FCC proposes that they will stop accepting applications for listing labs under section 2.948 as of the effective date of the final rules. The FCC proposes that any unaccredited labs that are already listed on the effective date of the rules can continue to perform testing until one year after publication, after that they must be accredited. All labs accredited or not, must comply with the site validation requirements of C63.4-2009 no later than one year after publication. Any new labs must comply with both accreditation and site validation requirements as of the date of publication of the new rules.

New single Australian compliance mark requirements

March 1, 2013 is the commencement date set for the new ACMA labeling arrangements. The three marks, C-Tick, A-Tick and RCM, are to be consolidated into a single compliance mark, the RCM.
The C-Tick and A-Tick marks will be phased out over a three year period, however, new suppliers will be required to register with the new database, and apply the new RCM on March 1, 2013.
The new marking does not affect the device compliance requirements. Testing, record-keeping and evidential requirements continue as set out in the relevant labeling notices.
A new safety system, the Electrical Equipment Safety System (EESS) is being introduced in some state territories and the RCM will be the only compliance mark for devices within the scope of the EESS.
Complete details provided below via a link in the reference listing.

FCC announces efforts to support U.S. Innovation Economy and free up new spectrum to expedite ultra-high-speed, high capacity Wi-Fi. The announcement was made at the 2013 International CES this month.

Chairman Julius Genachowski expressed that the FCC will soon kick-off a government wide effort to increase speeds and alleviate Wi-Fi congestion at major hubs. Among the examples given are large conference gatherings (such as CES perhaps), airports and convention centers, and the home network, where multiple users and devices are competing for network bandwidth and time and reducing the overall performance of the wireless network in general.

The intent is to free up, and increase, by up to 35%, unlicensed spectrum and make it available for ultra-high-speed, high capacity Wi-Fi, or as it’s commonly called “Gigabit Wi-Fi”.

The largest expansion of Wi-Fi since 2003, next month should bring the first steps of this action in the form of an additional 195 MHz of spectrum in the 5 GHz band.

It shouldn’t be long after that we begin to see consumer product on the shelves that take advantage of this, the first standard that will most likely make use of this available 5GHz spectrum, IEEE 802.11ac, has been in development for some time. This standard requires at least twice the bandwidth of the preceding 802.11n standard, but provides a potential speed increase of perhaps tenfold.

Radio module integration and R&TTE compliance, EMC evaluation

radio module (Photo credit: ckhamken)

Building on a previous post focusing on radio module integration and the Radio and telecommunications terminal equipment (R&TTE) directive compliance, this article will focus on compliance of the combined apparatus with section 3.1(b) of the R&TTE directive, namely the essential requirements of Electromagnetic Compatibility or EMC.

As a basic primer, the R&TTE directive’s essential requirements are detailed within the directive under article 3, to paraphrase;

3.1 Essential requirements applicable to all apparatus;

       a. Safety requirements of the Low Voltage Directive, with lower limits removed

       b. Electromagnetic compatibility as per EMC directive

3.2 Effective use of radio spectrum

3.3 Construction, protection and accessibility requirements (with a number of specified items)

As posited in a previous post “Radio module integration and R&TTE compliance”, compliant radio modules installed in accordance with a manufacturer’s installation instruction require no further evaluation to article 3.2 of the R&TTE directive. However, an assessment, in most cases, will be necessary for article 3.1(a) and 3.1(b). The combined product will essentially form a new apparatus.

Given that the combined product should be assessed as a new apparatus, a couple questions may arise. What EU directive and standards apply? How do you make an assessment for EMC on the combined product?

When adding a radio to an apparatus, the new combined apparatus now falls within the scope of the R&TTE directive. ETSI EN 301 489-1 annex C gives guidance regarding this combined equipment EMC assessment, and it is based on the ETSI TR 102 070-1 technical report. In accordance with the guidance, for a combined apparatus where all products can operate independently of each other, an evaluation may be made by review of existing assessment of the individual apparatus, and if it is concluded that the combined configuration has been assessed and is representative of the combined apparatus, and, is used in according to its manufacturer’s instructions, it is not necessary to re-assess the apparatus. If there is insufficient information to make an evaluation, or the results of the evaluation are unclear, then an additional assessment shall be performed. Most of the time an assessment for EMC of the combined apparatus will not have been performed, or there is insufficient data to support a declaration of conformity.

Although under the scope of the R&TTE directive, the selection of applicable standards for EMC will be based on the primary function of the newly combined apparatus. The manufacturer shall declare the primary function and identify applicable standards from the EMC directive and/or R&TTE directive. The assessment should be supplemented with test levels and extended frequency ranges to cover both radio and non-radio aspects of the newly combined apparatus (i.e. a worst case representation of applicable levels and limits). See this flow chart from Compatible Electronics for a simplification of the assessment process based on the ETSI guidance.

The declaration of conformity will need to declare compliance with the R&TTE directive, and the party responsible for the completed combined apparatus is the party responsible for ensuring that the final configuration, when used properly, and in accordance with the provided instructions, fulfills ALL essential requirements of the R&TTE directive.

GUIDELINES ON THE APPLICATION OF DIRECTIVE 2006/95/EC (par. 34)

FCC policy and procedure updates, it’s a big one

Logo of the United States Federal Communications Commission, used on their website and some publications since the early 2000s. (Photo credit: Wikipedia)

The Knowledge Database section of the Office of Engineering and Technology (OET) web site has a significant number of new publications today. The new updates impact technical requirements such as software defined radios, RF safety and Digital Transmission Systems (DTS) measurement procedures. Other updates cover administrative issues as well as  guidance and policy for Telecommunication Certification Bodies.

While the FCC continually updates these policies and procedures as needed, we tend to see the most significant changes going into the spring and fall seasons. Part of the reason for this is the TCB council holds regular training workshops in the spring and fall. The FCC is generally in attendance, and uses the opportunity to update the community on policy matters and technical issues. The training workshops become sort of a deadline for publication in this way. We also see a number of updates just following the training workshops as questions and comments begin to hit the FCC.

You can visit the OET KDB site at https://apps.fcc.gov/oetcf/kdb/index.cfm. Below is a categorized summary with excerpts of the updates for your convenience. If these issues are important to you, I suggest regular checks of the FCC KDB publications to stay current with the rules.
