2 RF Exposure 2.1 Limits for Maximum Permissible Exposure (MPE) Frequency Range Electric Field Magnetic Field Power Density Average Time (MHz) Strength (V/m) Strength (A/m) (mW/cm2) (minutes) Limits For General Population / Uncontrolled Exposure 300-1500 … … F/1500 30 1500-100,000 … … 1.0 30 F = Frequency in MHz 2.2 MPE 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 2.3 Classification The antenna of this product, under normal use condition, is at least 37cm away from the body of the user. So, this device is classified as Mobile Device. Report No.: SA190220C23 Page No. 5 / 6 Report Format Version: 6.1.1

3 Calculation Result of Maximum Conducted Power Frequency Band Max Power Antenna Gain Distance Power Density Limit (MHz) (dBm) (dBi) (cm) (mW/cm2) (mW/cm2) CDD Mode 2412-2462 29.53 9.02 37 0.416 1 5180-5240 28.41 10.02 37 0.405 1 5745-5825 29.66 10.02 37 0.540 1 Beamforming Mode 2412-2462 27.93 9.02 37 0.288 1 5180-5240 27.03 10.02 37 0.295 1 5745-5825 28.17 10.02 37 0.383 1 *Determining compliance based on the results of the compliance measurement, not taking into account measurement instrumentation uncertainty. Note: 1. Directional gain: 2.4GHz Band: Directional gain = 3dBi + 10log(4) = 9.02dBi 5GHz Band: Directional gain = 4dBi +10log (4) = 10.02dBi 2. The above Max Power is Turn-up Power which client declaried. Conclusion: 2.4GHz & 5GHz Band 1 or 2.4GHz & 5GHz Band 4 can transmit at same time. The formula of calculated the MPE is: CPD1 / LPD1 + CPD2 / LPD2 + ……etc. < 1 CPD = Calculation power density LPD = Limit of power density 1. WLAN 2.4GHz + WLAN 5GHz Band 1 = 0.416 + 0.405 = 0.821 2. WLAN 2.4GHz + WLAN 5GHz Band 4 = 0.416 + 0.540 = 0.956 Therefore the maximum calculations of above situations are less than the “1” limit. ---END--- Report No.: SA190220C23 Page No. 6 / 6 Report Format Version: 6.1.1
