2 RF Exposure 2.1 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) 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 2 Pd = (Pout*G) / (4*pi*r ) where 2 Pd = power density in mW/cm 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 23cm away from the body of the user. So, this device is classified as Mobile Device. Report No.: SA161125E01E Page No. 5 / 7 Report Format Version: 6.1.1 Reference No.: 171113E01

2.4 Antenna Gain WLAN (Radio 1) Antenna Frequency range Directional Antenna Gain (dBi) Antenna Type Connecter Type (GHz) 2.4~2.4835 5.9 5.47~5.725 5.89 PIFA NA 5.725~5.85 5.89 WLAN (Radio 2) Antenna Frequency range Directional Antenna Gain (dBi) Antenna Type Connecter Type (GHz) 5.15~5.25 4 PIFA NA 5.25~5.35 4 Report No.: SA161125E01E Page No. 6 / 7 Report Format Version: 6.1.1 Reference No.: 171113E01

2.5 Calculation Result of Maximum Conducted Power For BT-LE, 2.4GHz and 5GHz (U-NII-1 band / U-NII-3 band) data was copied from the original test report (Report No.: SA161125E01D) Radio 1 (WLAN: Dual Band): Frequency Max Power Antenna Gain Distance Power Density Limit 2 2 (MHz) (mW) (dBi) (cm) (mW/cm ) (mW/cm ) 2412-2462 798.221 5.90 23 0.46715 1 5500-5700 237.807 5.89 23 0.13885 1 5745-5825 567.608 5.89 23 0.33142 1 Radio 2(WLAN: Single Band) Frequency Max Power Antenna Gain Distance Power Density Limit 2 2 (MHz) (mW) (dBi) (cm) (mW/cm ) (mW/cm ) 5180-5240 309.071 4.00 23 0.11679 1 5260-5320 247.69 4.00 23 0.09359 1 NOTE: 2.4GHz: Directional gain = 5.90dBi 5GHz: U_NII-1: Directional gain = 4.00dBi U_NII-2A: Directional gain = 4.00dBi U_NII-2C: Directional gain = 5.89dBi U_NII-3: Directional gain = 5.89dBi Conclusion: The formula of calculated the MPE is: CPD1 / LPD1 + CPD2 / LPD2 + ……etc. < 1 CPD = Calculation power density LPD = Limit of power density WLAN 2.4GHz + WLAN 5GHz(UNII-3) + WLAN 5GHz(UNII-1) = 0.46715 / 1 + 0.11679 / 1 + 0.33142 / 1 = 0.91536 Therefore the maximum calculations of above situations are less than the “1” limit. --- END --- Report No.: SA161125E01E Page No. 7 / 7 Report Format Version: 6.1.1 Reference No.: 171113E01
