Question: What are the RF exposure requirements and procedures for mobile and portable devices?
Answer:
Mobile and portable device RF exposure and equipment authorization requirements are found in 47 CFR Sections 1.1307, 2.1091, and 2.1093.Attachment 447498 D01 General RF Exposure Guidance v06provides guidance pertaining to RF exposure requirements for mobile and portable device equipment authorizations.Attachment 447498 D02 SAR Procedures for Dongle Xmtr v02r01provides guidance for SAR testing of USB dongle transmitters.Attachment 447498 D03 Supplement C Cross-Referenceprovides a cross-reference between the discontinued OET Bulletin 65 Supplement C-0101 and the applicable KDB publications.Attachment 447498 D04 Interim General RF Exposure Guidance v01 provides guidance under interim procedures See note Notes to 447498 D04 Interim General RF Exposure Guidance below for details.A spreadsheet for Mobile Multi-transmitter MPE Estimation for estimating MPE limits for multiple antennas is available at:http://www.fcc.gov/oet/ea/presentations/files/oct05/MPE-mobile.xlsNotes to 447498 D04 Interim General RF Exposure Guidance:447498 D04 Interim General RF Exposure Guidance is based on the existing policies and procedures of KDB Publication 447498 D01 v06 with modifications and updates following from the rules adopted in the Second Report and Order in ET Docket No. 03-137 (FCC 19-126; paras. 17 to 118 and Appendix A; 34 FCC Rcd 11697-11742 and 11762-11781).The effective date for the rule changes in §§ 1.1307, 2.1091, and 2.1093 per FCC 19-126 is May 3, 2021, as stated in Public Notice DA 21-363 (Apr. 2, 2021). Modifications to various other rules adopted in FCC 19 126 went into effect on June 1, 2020.Existing equipment authorizations remain valid and do not require specific modifications further to the FCC 19-126 rule changes. Certification applications for new and modified equipment must follow the most recent equipment authorization policies and procedures in effect at the time of the application.This document is not related to the rulemaking in ET Docket No. 19-226 (Notice of Proposed Rulemaking (NPRM) FCC 19-126, paras. 119 to 147 and Appendix B; 34 FCC Rcd 11742-11756 and 11782-11788). Comments on the proposed rulemaking topics should be filed directly using the FCC Electronic Comment Filing System (ECFS; https://www.fcc.gov/ecfs/).
Transition Period until March 31, 2022:Attachment "447498 D04 Interim General RF Exposure Guidance v01" can be used for equipment authorization and must be used in its entirety along with any other associated revised KDB RF exposure procedures and policies (including FCC-TCB conference presentations).The previous version, "447498 D01 General RF Exposure Guidance v06," may also be used during the interim period as long as the 731 Form and the related granted application to the FCC are submitted on or before March 31, 2022. "447498 D01 General RF Exposure Guidance v06" must be used entirely (i.e., no mixing of old and new procedures for a certification application(s) filing).After March 31, 2022, all applications must only use new procedures which will be published as "D01 447498 General RF Exposure Guidance v07", and based on "447498 D04 Interim General RF Exposure Guidance", replacing KDB "447498 General RF Exposure Guidance v06".The only exception is cases where a certification application(s) includes items subject to Pre-Approval Guidance (PAG, KDB Publication 388624) submitted prior to April 1, 2022. In this case, the TCB can grant the device after the deadline of March 31, 2022, using "447498 General RF Exposure Guidance v06" after the PAG is approved.
Attachment List:

主要更新内容
[*]新版对于便携式设备的SAR评估要求更为严格, 2.4GHz产品功率大于2.7mW(4.3dBm),5G产品功率大于1mW(0 dBm)必须要进行SAR测量以证明符合性. 旧版本在10dBm以下可以使用豁免SAR测试的方式证明符合性.
[*]新版自发布之日起, 开始过渡使用V07版KDB，过渡期间V06版与V07版都可以接受，但不能新旧评估程序混合使用；2022-03-31后开始强制实施V07版。
对客户的影响
新版本对便携式设备的SAR评估要求更加严格， 进行SAR测试会增加额外的测试周期和成本，最终获得证书周期也会延长。 建议制造商综合评估需求后进行设计和生产。
