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 30cm away from the body of the user. So, this device is classified as Mobile Device. Report No.: SA161028D01A Page No. 5 / 6 Report Format Version: 6.1.1 Reference No.: 161028D01, 161206D08

2.4 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 29.16 9.26 35 0.4515 1 (Original Approved) 5180-5240 29.53 9.61 35 0.5329 1 (Original Approved) 5260-5320 23.94 6.95 35 0.0797 1 5500-5700 23.92 7.14 35 0.0829 1 5745-5825 29.62 9.16 35 0.4905 1 (Original Approved) NOTE: 2.4GHz Directional gain = 10 log[(10G1/20 + 10G2/20 + ... + 10GN/20)2 / 4] = 9.26dBi 5180-5240MHz Directional gain = 10 log[(10G1/20 + 10G2/20 + ... + 10GN/20)2 / 4] = 9.61dBi 5.260-5.320GHz Directional gain = 6.95dBi 5.500-5.700GHz Directional gain = 7.14dBi 5745-5825MHz Directional gain = 10 log[(10G1/20 + 10G2/20 + ... + 10GN/20)2 / 4] = 9.16dBi The directional antenna gain information is declared by manufacturer and more detailed features description please refer to operation description of antenna specifications exhibit. 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 = 0.4515 + 0.5329 = 0.9844 Therefore the maximum calculations of above situations are less than the “1” limit. --- END --- Report No.: SA161028D01A Page No. 6 / 6 Report Format Version: 6.1.1 Reference No.: 161028D01, 161206D08
