2. RF EXPOSURE 2.1 LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) FREQUENCY ELECTRIC FIELD MAGNETIC FIELD POWER DENSITY AVERAGE TIME RANGE (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.: SA130318C03 5 of 6 Report Format Version 5.0.0

2.4 CALCULATION RESULT OF MAXIMUM CONDUCTED POWER FREQUENCY ANTENNA POWER MAX POWER DISTANCE LIMIT BAND GAIN DENSITY (dBm) (cm) (mW/cm2) (MHz) (dBi) (mW/cm2) 2400-2483.5 28.61 2 20 0.144 1 5150-5250 16.67 2 20 0.009 1 5250-5350 19.35 2 20 0.017 1 5470-5725 19.16 2 20 0.016 1 5725-5825 26.21 2 20 0.083 1 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 = 0.144 + 0.083 = 0.227 Therefore all the maximum calculations of above situations are less than the “1” limit. ---END--- Report No.: SA130318C03 6 of 6 Report Format Version 5.0.0
