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 20cm away from the body of the user. So, this device is classified as Mobile Device. Report No.: SA181024C03A Page No. 5 / 6 Report Format Version: 6.1.1 Reference No.: 181024C04

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 24.88 6.07 20 0.248 1 5180-5240 27.19 4.34 20 0.283 1 5260-5320 23.50 4.15 20 0.116 1 5500-5720 23.38 4.17 20 0.113 1 5745-5825 28.14 4.80 20 0.391 1 Beamforming Mode 5180-5240 27.13 4.34 20 0.279 1 5180-5240 23.50 4.15 20 0.116 1 5260-5320 23.38 4.17 20 0.113 1 5745-5825 27.95 4.80 20 0.375 1 Note: 2412~2462MHz Directional gain = 10 log[(10G1 /20 + 10G2 /20 + ... + 10GN /20)2/3]= 6.07dBi 5180~5240MHz Directional gain = 4.34dBi 5260~5320MHz Directional gain = 4.15dBi 5500~5700MHz Directional gain = 4.17dBi 5745~5825MHz Directional gain = 4.80dBi Conclusion: Both of the WLAN 2.4G & WLAN 5G can transmit simultaneously, the formula of calculated the MPE is: CPD1 / LPD1 + CPD2 / LPD2 + ……etc. < 1 CPD = Calculation power density LPD = Limit of power density 2.4G + 5G = 0.248 / 1 + 0.391 / 1 = 0.639 Therefore the maximum calculations of above situations are less than the “1” limit. ---END--- Report No.: SA181024C03A Page No. 6 / 6 Report Format Version: 6.1.1 Reference No.: 181024C04
