Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: 2401T36383E-RFA TR-EM-RF012 Page 18 of 80 Version 3.0 FCC §15.247 (i) & §1.1307 (b) (3) & §2.1091- RF EXPOSURE Applicable Standard According to KDB 447498 D04 Interim General RF Exposure Guidance 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). f = frequency in MHz; R = minimum separation distance from the body of a nearby person (appropriate units, e.g., m); Result For worst case: Mode Frequency (MHz) Tune up conducted power # Antenna Gain # ERP Evaluation Distance (m) ERP Limit (mW) (dBm) (dBi)(dBd)(dBm)(mW) 2.4G Wi-Fi 2412-2462 24.5 4.45 2.30 26.80 478.63 0.2 768 5.2G Wi-Fi 5180-5240 11.0 4.95 2.80 13.80 23.99 0.2 768 5.3G Wi-Fi 5260-5320 11.0 4.95 2.80 13.80 23.99 0.2 768 5.6G Wi-Fi 5500-5700 10.0 4.95 2.80 12.80 19.05 0.2 768 5.8G Wi-Fi 5745-5825 9.0 4.95 2.80 11.80 15.14 0.2 768 Note 1: The tune-up power and antenna gain was declared by the applicant. Note 2: 0dBd=2.15dBi. Note 3: the 2.4G and 5G Wi-Fi cannot transmit at same time To maintain compliance with the FCC’s RF exposure guidelines, place the equipment at least 20cm from nearby persons. Result: Compliant
