According to KDB 447498 D04 Interim General RF Exposure Guidance SAR-Based Exemption: SAR-based thresholds are derived based on frequency, power, and separation distance of the RF source. The formula defines the thresholds in general for either available maximum timeaveraged power or maximum time-averaged ERP, whichever is greater. Per § 1.1307(b)(3)(i)(B), for single RF sources (i.e., any single fixed RF source, mobile device, or portable device, as defined in paragraph (b)(2) of this section): A single RF source is exempt if: the available maximum time-averaged power or effective radiated power (ERP), whichever is greater, is less than or equal to the threshold P th (mW) described in the following formula. This method shall only be used at separation distances (cm) from 0.5 centimeters to 40 centimeters and at frequencies from 0.3 GHz to 6 GHz (inclusive). P th is given by: For multiple RF sources: Multiple RF sources are exempt if: in the case of fixed RF sources operating in the same time-averaging period, or of multiple mobile or portable RF sources within a device operating in the same time averaging period, if the sum of the fractional contributions to the applicable thresholds is less than or equal to 1 as indicated in the following equation: Shenzhen Accurate Technology Co., Ltd.

Note 2: 0dBd=2.15dBi. Note 3: the 2.4G Wi-Fi and 5G Wi-Fi can transmit at same time Note 4. The device employ beamforming for 802.11n/ac/ax mode. Direction Gain = G ANT + 10*log(N ANT /N SS ) For EUT, N ANT =2, for the worst case, N SS =1 For 5G Wi-Fi, G ANT1 =4.79dBi, G ANT2 =5.37dBi, use the higher gain 5.37dBi for the calculate So, the direction Gain=5.37dBi+10*log(2/1)=8.37dBi For 2.4G Wi-Fi, GANT1=3.3dBi, GANT2=3.51dBi, use the higher gain 3.51dBi for the calculate So, the direction Gain=3.51dBi+10*log(2/1)=6.51dBi Simultaneous transmitting consideration (worst case): The ratio=P 2.4G /Pth+P 5G /Pth=685.49/3060+1485.94/3060=0.71＜1.0, so simultaneous exposure is compliant. To maintain compliance with the FCC’s RF exposure guidelines, place the equipment at least 20cm from nearby persons. Result: Compliant.
