RF EXPOSURE EVALUATION REPORT Report No. : FA6D2013-01 3. RF Exposure Limit Introduction According to ANSI/IEEE C95.1-1992, the criteria listed in Table 1 shall be used to evaluate the environmental impact of human exposure to radio frequency (RF) radiation as specified in §1.1310. The MPE was calculated at 20 cm to show compliance with the power density limit. The following formula was used to calculate the Power Density: 𝐏𝐆 𝐒= 𝟒𝛑𝐑𝟐 Where: S = Power Density P = Output Power at Antenna Terminals G = Gain of Transmit Antenna (linear gain) R = Distance from Transmitting Antenna TEL : 886-3-327-3456 Page : 6 of 7 FAX : 886-3-328-4978 Issued Date : Aug. 08, 2018 Form version: 180516

Standalone Power Density Calculation <For ESP32> Power Antenna Maximum Maximum Maximum Average Frequency Density at Limit Band Gain Power EIRP EIRP EIRP (MHz) 20cm (mW/cm^2) (dBi) (dBm) (dBm) (W) (mW) (mW/cm^2) Bluetooth 2402.0 2.5 0.5 3.000 0.002 1.995 0.0004 1.000 2.4GHz WLAN 2412.0 2.5 13.0 15.500 0.035 35.481 0.0071 1.000 Note: For conservativeness, the lowest frequency of each band is used to determine the MPE limit of that band. Conclusion: According to 47 CFR §2.1091, the RF exposure analysis concludes that the RF Exposure is FCC compliant.
