FCC KDB Update

FCC KDB 974614 D01 v05 introduced a two-year transition period for accepting standards ANSI/TIA-603-D-2010 and ANSI/TIA-102.CAAA-D-2013. These two standards can be used until March 2nd, 2020. KDB 388624 D02 PAG List: LTE-U and LAA devices were removed as well as 700 MHz Band devices under Part 74. Part 30 devices were added into the list. Certain wireless power transferring (WPT) devices remain on the list, but the exclusion criteria have been updated. KDB 680106 D01 v03 updated the criteria for WPT devices to be exempted from submitting a KDB for device approval.

The major updates involve increased output power, the removal of the maximum coupling surface area requirement, and the clarification of the aggregate leakage fields requirement. Clarification has been given by the FCC regarding DFS evaluation for 802.11ax. 802.11ax, which allows for 80 MHz and 160 MHz channels to notch a 20 MHz portion of their operating bandwidth when radar is detected within that 20 MHz slice of the spectrum. Therefore, channel closing and move times should be verified when a 20 MHz channel sees radar. This step should be repeated for a second 20 MHz channel. Innovation Science and Economic Development (ISED) published Radio Standards Specification GEN (RSS-GEN), Issue 5, General Requirements for Compliance of Radio Apparatus on April 26, 2018. The new release replaces RSS-Gen Issue 4, dated November 2014. A transition period of six months following the standard’s publication is provided.

Compliance with Issue 4 or Issue 5 will be accepted within the transition period. The product-specific standard EN 303 413 for Global Navigation Satellite System (GNSS) receivers was harmonized earlier this year. The harmonization of the product-specific standards indicates that generic standard EN 300 440 cannot be used as a standard to demonstrate compliance with article 3.2 of directive 2014/53/EU. BACL is capable of GNSS receiver testing in accordance with EN 303 413. The Spirent GSS7000 signal generator supports GPS (L1, L2, L5), GLONASS (G1, G2), Galileo (E1, E5), BDS, and SBAS. The Spirent GSS7725 interference generator provides an interference signal as specified in the regulation rules.

This Spirent system enables an automatic adjacent frequency band selectivity test, and the simulation of multiple constellations simultaneously for receiver spurious emissions testing. The transition period for Adaptivity from EN 301 893 V1.8.1 to V2.1.1 is due at the end of 2018. After December 6th, 2018, manufacturers of 5 GHz RLAN devices must show compliance to Clause 4.2.7 of EN 301 893 V2.1.1 in order to place their devices on the European market. BACL’s testing capabilities are up-to-date with the EU RED harmonized standards; please feel free to contact us if you haven’t yet updated your device to the latest standards. The Korea National Radio Research Agency (RRA) reminds all test laboratories to follow the measurement equipment calibration requirements.  The RRA also provided the list below, which contains the maximum nominal calibration interval.
