United States

The Federal Communications Commission (FCC) is expanding the Knowledge Data Base (KDB). There are a few things that are worth noting.5

KDB 726920 on confidentiality was updated on December 21, 2011. Internal photographs and user manuals can apply for long term confidentiality under special circumstances. Before this update, requests for confidentiality of these types of exhibits were not accepted. When requesting for confidentiality for an internal photo, it is necessary to indicate under a separate cover that a user cannot check the subject of the photo easily. There is merit to make the internal photo confidential as others will not be able to look at the enclosed circuit and estimate what components have been used.

KDB 558074 Section 15.247 on measurement requirements for digital modulation equipment was published on January 18, 2012. This provides guidance for power density measurement and performing measurement for unwanted emission.

KDB 789033 Guidelines for Compliance Testing of Unlicensed National Information Infrastructure (U-NII) Devices was also published on October 25, 2011 which replaced former measurement procedure DA 02-2138. Readers should be mindful of the requirement on normalization of continuous transmission, etc. It should also be noted that the spurious limit in Section 15.407 is more stringent than the limit of a restricted band. In addition, a new document was added to KDB 662911 for emission testing of multi-transmission systems in the same band. This states the simple sum / sum of squares in radiated emission for cross-polarized antenna.

The following were also published:

• KDB 684743 for the limits for fixed narrow beam point-to-point operation in Section 15.249 (b) operating in the 24 GHz band on August 11, 2011,
• KDB 617965 for Part 95 MICS, Human Torso Simulator and Testing Technique on August 11, 2011,
• KDB 416721 for white space testing procedure on December 16, 2011,
• KDB 892282 for battery charger and associated digital electronics on-board a vehicle on January 21, 2012 and this battery charger is subject to an FCC equipment authorization.

KDB 690783 SAR (Specific Absorption Rate) Listings on Grants was published on October 25, 2011. Telecommunications Certification Bodies (TCB) should pay attention to the following:

• the highest SAR values for each of the evaluated exposure conditions across the frequency bands and wireless modes must be identified and listed;
• numeric values used for SAR listings on grants should be rounded to two decimal points;
• Class II permissive change filings should list the highest SAR values across all filings under an FCC ID, within each equipment class.

KDB 648474 SAR Evaluation for Handsets that Contain Multiple Transmitters and Antennas was updated on January 3, 2012 and new document for evaluation of wireless charging battery covers was added.

On October 25, 2011, Part 15 Subpart G was deleted from KDB 628591 as the measurement guidelines can be found in FCC 11-160 Measurement Guidelines for Broadband Over Power Line (BPL) Devices. On the same day, KDB 610077 Post-Market Surveillance Requirements for TCBs was updated. General changes include clarification of the follow-up action for non-compliant devices and specifying the minimum information to be included in the annual summary.

Based on changing standards on mobile phones, KDB 388624 Permit But Ask was revised on January 4, 2012 in which wireless chargers were added. KDB 546630 TCB Supersede Procedures was updated on January 24, 2012 to conform to the new policy of allowing more than two exhibit types per application to be superseded.

In addition to KDB updating, on February 1, 2012 the FCC also decided to remove outdated regulations such as transition period.6 Accordingly, the FCC deleted Section 15.37 regarding a transition period for conduction testing of CISPR harmonization and Section 18.123, as well as corrected Sections 15.117, 15.120, 15.123 and 15.124 regarding digital broadcasting transition.

Canada

Industry Canada revised RSS-GEN and RSS-310 which simplified the handling of receivers. Only scanner receivers require equipment certification and only stand-alone receivers that operate in the band 30MHz to 960MHz require testing and labeling.7 Therefore receivers contained in transmitters are excluded from requirements for testing, labeling and provision of a manual. In addition, electronic labeling will be allowed. CB-02 was updated in October, 2011 to clarify surveillance requirements and to correct Section 6.5 in order to avoid misinterpretation of the necessary certification therein.

Attention should be paid to the time of delivery which should be the listing date on Industry Canada’s Radio Equipment List homepage and not the approval date by a Foreign Certification Body (FCB). In general, about a week is required for Industry Canada to list the equipment online after FCB approval.

Furthermore, a revision of ICES-003 which governs the EMC testing requirement for information technology equipment (ITE) is planned. This will include the EMCAB-3 guidance document, requirements for ITE above 1 GHz (note: this is partly different from Comité International Spécial des Perturbations Radioélectriques (CISPR) – 1~6GHz Class A 49.5dBμ @10m and Class B 54.0dBμ @3m). CISPR 22 Ed.6 or ANSI C63.4:2009 will be adopted as testing methods.
