The following subparts are applicable to the results in this test report. Part 1, Subpart I Practice and Procedure, Procedures Implementing the National Environmental Policy Act of 1969 § 1.1307: Actions that may have a significant environmental effect, for which Environmental Assessments (EAs) must be prepared. Part 2, Subpart J Equipment Authorization Procedures, Certification § 2.1091: Radiofrequency radiation exposure evaluation: mobile devices. § 2.1093: Radiofrequency radiation exposure evaluation: portable devices. The following KDB is applied: KDB 447498 D04, v01: Interim General RF Exposure Guidance RF Exposure Procedures and Equipment Authorization Policies for Mobile and Portable Devices TEST REPORT REFERENCE: MDE_BVUS_2407_MPE_02 Page 4 of 13 2 Summary This RF-exposure evaluation according to the – in chapter 1 - mentioned rule parts and KDB shows, that the worst-case RF exposure values of the assessed radio technologies and bands are below the exemption limits of the mentioned rule parts. The following exemption rule part(s) were selected: ☐ 1-mW Test Exemption, § 1.1307(b)(3)(i)(A) 447498 D04 Interim General RF Exposure Guidance v01, 2.1.2 Per § 1.1307(b)(3)(i)(A), a single RF source is exempt RF device (from the requirement to show data demonstrating compliance to RF exposure limits, as previously mentioned) if the available maximum time-averaged power is no more than 1 mW, regardless of separation distance. This exemption applies to all operating configurations and exposure conditions, for the frequency range 100 kHz to 100 GHz, regardless of fixed, mobile, or portable device exposure conditions. This is a standalone exemption, and it cannot be applied in conjunction with any other test exemption. ☒ MPE based test exemption, § 1.1307(b)(3)(i)(C) 447498 D04 Interim General RF Exposure Guidance v01, 2.1.4 An alternative to the SAR-based exemption is provided in § 1.1307(b)(3)(i)(C), for a much wider frequency range, from 300 kHz to 100 GHz, applicable for separation distances greater or equal to λ/2π, where λ is the free-space operating wavelength in meters. The MPE-based test exemption condition is in terms of ERP, defined as the product of the maximum antenna gain and the delivered maximum time- averaged power.10 For this case, a RF source is an RF exempt device if its ERP (watts) is no more than a frequency-dependent value, as detailed tabular form in Appendix B. These limits have been derived based on the basic specifications on Maximum Permissible Exposure (MPE) considered for the FCC rules in § 1.1310(e)(1). ☐ SAR based test exemption, § 1.1307(b)(3)(i)(B) 447498 D04 Interim General RF Exposure Guidance v01, 2.1.3 A more comprehensive exemption, considering a variable power threshold that depends on both the separation distance and power, is provided in § 1.1307(b)(3)(i)(B). This exemption is applicable to the frequency range between 300 MHz and 6 GHz, with test separation distances between 0.5 cm and 40 cm, and for all RF sources in fixed, mobile, and portable device exposure conditions. Accordingly, a RF source is considered an RF exempt device if its available…
