Report No.: 1610RSU00308 2. RF Exposure Evaluation 2.1. Limits FCC Rules: According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environment impact of human exposure to radio frequency (RF) radiation as specified in 1.1307(b) LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) Frequency Range Electric Field Magnetic Field Power Density Average Time 2 (MHz) Strength (V/m) Strength (A/m) (mW/cm ) (Minutes) (A) Limits for Occupational/ Control Exposures 300-1500 -- -- f/300 6 1500-100,000 -- -- 5 6 (B) Limits for General Population/ Uncontrolled Exposures 300-1500 -- -- f/1500 6 1500-100,000 -- -- 1 30 FCC ID: H8N-WHD0100 Page Number: 4 of 6

Report No.: 1610RSU00308 Formula as follows: f= Frequency in MHz Calculation Formula: Pd = (Pout*G)/(4*pi*r2) Where Pd = power density in mW/cm2 Pout = output power to antenna in mW G = gain of antenna in linear scale Pi = 3.1416 r = distance between observation point and center of the radiator in cm Pd is the limit of MPE, 1mW/cm². If we know the maximum gain of the antenna and the total power input to the antenna, through the calculation, we will know the distance r where the MPE limit is reached.

Report No.: 1610RSU00308 2.2. Test Result of RF Exposure Evaluation Product Cloud Client Box Test Item RF Exposure Evaluation Antenna Gain: The maximum Gain measured in fully anechoic chamber is 1.59dBi for Wi-Fi and Bluetooth band. For 2.4GHz Wi-Fi Band: Test Mode Frequency Band Maximum Average Power Density at FCC (MHz) Output Power r = 20 cm Limit 2 (dBm) (mW/cm ) (mW/cm2) 802.11b 2412 ~ 2462 21.35 0.0391 1 802.11g 2412 ~ 2462 19.32 0.0245 1 802.11n-HT20 2412 ~ 2462 19.01 0.0228 1 802.11n-HT40 2422 ~ 2452 18.91 0.0223 1 For Bluetooth Band: Test Mode Frequency Band Maximum Peak Power Density at FCC (MHz) Output Power r = 20 cm Limit 2 (dBm) (mW/cm ) (mW/cm2) BLE 2402 ~ 2483.5 0.61 0.0003 1 DH5 2402 ~ 2483.5 5.77 0.0011 1 2DH5 2402 ~ 2483.5 7.09 0.0015 1 3DH5 2402 ~ 2483.5 7.53 0.0016 1 CONCULISON: Both of the WLAN and Bluetooth can transmit simultaneously. Therefore, the Max Power Density at r (20 cm) = 0.0391mW/cm2+ 0.0016mW/cm2 = 0.0407mW/cm2 < 1mW/cm2. So the EUT complies with the FCC requirement. The End FCC ID: H8N-WHD0100 Page Number: 6 of 6
