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. 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) 2412-2462 27.48 6 20 0.443 1 5180-5240 21.11 7.01 20 0.129 1 5745-5825 20.32 7.01 20 0.108 1 Note: 2.4GHz: Directional gain = 3dBi + 10log(2) = 6dBi 5GHz: Directional gain = 4dBi + 10log(2) = 7.01dBi 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 = 0.443 + 0.129 = 0.572 Therefore all the maximum calculations of above situations are less than the “1” limit. ---END--- Report No.: SA121023C05A Page No. 5 / 5 Report Format Version: 6.1.1 Reference No.: 150807C21
