Shenzhen Accurate Technology Co., Ltd. Report No.: SZ3220513-20217E-RF Version 12: 2021-11-09 Page 11 of 61 FCC- 2.4G Wi-Fi FCC §1.1307 (b) – RF EXPOSURE EVALUATION Applicable Standard According to KDB 447498 D04 Interim General RF Exposure Guidance v01, clause 2.1.4 –MPE-Based Exemption: 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. 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). Table to § 1.1307(b)(3)(i)(C) - Single RF Sources Subject to Routine Environmental Evaluation f = frequency in MHz; R = minimum separation distance from the body of a nearby person (appropriate units, e.g., m); Test Result For worst case: Frequency Range (MHz) Tune-up Output Power Antenna Gain ERP Evaluation Distance (cm) MPE-Based Exemption Threshold (mW) (dBm) (mW) (dBi) (dBd) (dBm) (mW) 2412-2462 20.5 112.2 1 -1.15 19.35 86.10 20 768 Note 1: The tune-up power was declared by the applicant. Note 2: 0dBd=2.15dBi. To maintain compliance with the FCC’s RF exposure guidelines, place the equipment at least 20cm from nearby persons. Result: Compliant.
