The FCC presented updates regarding its radio frequency (RF) exposure guidelines during the semi-annual TCB Council workshop on April 20 – 22. The highlights are:
Canadian and German government agencies also made statements in April about SAR measurement standards. ISED published an updated Notice 2020-DRS0020 on April 20, 2021, that IEC/IEEE 62209-1528 has been adopted in Canada with the exception of procedures for measurement of Time-Average SAR, LTE mode, and the 6 – 10 GHz frequency range. This Notice also stated that IEC 62209-3 is not accepted, re-affirming their position in a previous Notice in January 2020. The German Federal Network Agency (Bundesnetzagentur or BNetzA) made an agreement last month with the German notified bodies not to accept the results of SAR array systems for conformance of wireless devices, although they may be used for pre-screening. This agreement, which is similar to the statements of the FCC and ISED, applies until improvements in both the standards and manufacturer implementations are published.
SPEAG and the IT’IS Foundation are committed to working with the standard groups and regulators toward eliminating the important technical shortcomings of IEC 62209-3 that cause substantial differences in the test results (amounting to several dBs), with the goal of making IEC 62209-3 technically equivalent to IEC/IEEE 62209-1528. To achieve this, one main focus will be to strengthen the performance validation sections, i.e., the sources, protocols and acceptance criteria.
