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 20cm away from the body of the user. So, this device is classified as Mobile Device. 2.4 Antenna Gain Frequency Antenna Antenna Net. Antenna Connecter Brand Model Chain No. range Set. Gain(dBi) Type Type (MHz) 2.98 2400~2500 Chain 0(Aux) 5.16 4900~5900 1 MAG.LAYERS MSA-4008-25GC1-A1 PIFA i-pex(MHF) 2.98 2400~2500 Chain 1(Main) 5.16 4900~5900 Report No.: SA161216E08 Page No. 5 / 6 Report Format Version: 6.1.1

2.5 Calculation Result of Maximum Conducted Power For WLAN: Frequency Max Power Antenna Gain Distance Power Density Limit Band 2 2 (mW) (dBi) (cm) (mW/cm ) (mW/cm ) (MHz) 2412-2462 931.528 5.99 20 0.73608 1 5180-5240 151.716 8.17 20 0.19804 1 5260-5320 148.092 8.17 20 0.19331 1 5500-5700 136.98 8.17 20 0.17881 1 5745-5825 194.363 8.17 20 0.25371 1 NOTE: 2.4GHz: Directional gain = 2.98dBi + 10log(2) = 5.99dBi 5GHz: Directional gain = 5.16dBi + 10log(2) = 8.17dBi For BT-EDR: Frequency Max Power Antenna Gain Distance Power Density Limit Band 2 2 (mW) (dBi) (cm) (mW/cm ) (mW/cm ) (MHz) 2402-2480 4.592 2.98 20 0.00181 1 For BT-LE: Frequency Max Power Antenna Gain Distance Power Density Limit Band 2 2 (mW) (dBi) (cm) (mW/cm ) (mW/cm ) (MHz) 2402-2480 2.754 2.98 20 0.00109 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 + Bluetooth = 0.73608 / 1 + 0.00181 / 1 = 0.73789 WLAN 5GHz + Bluetooth = 0.25371 / 1 + 0.00181 / 1 = 0.25552 Therefore the maximum calculations of above situations are less than the “1” limit. --- END --- Report No.: SA161216E08 Page No. 6 / 6 Report Format Version: 6.1.1
