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 0.3-1.34 614 1.63 (100)* 30 1.34-30 824/f 2.19/f (180/f2)* 30 30-300 27.5 0.073 0.2 30 300-1500 … … f/1500 30 1500-100,000 … … 1.0 30 f = Frequency in MHz ; *Plane-wave equivalent power density 2.2 MPE Calculation Formula Pd = (Pout*G) / (4*pi*r2) where Pd = power density in mW/cm 2 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.: SA181120C09A Page No. 5 / 6 Report Format Version: 6.1.1 Reference No.: 190129C22

2.4 Antenna Gain Gain(dBi) Frequency Connector Cable Including cable Antenna Type range Type Length loss 2.69 777-787MHz PIFA i-pex(MHF) 84 mm 2.5 Calculation Result Frequency Max. ERP Max. EIRP Max. EIRP Distance Power Density Limit Band Power Power Power (cm) (mW/cm2) (mW/cm2) (MHz) (dBm) (dBm) (mW) 779.5 ~ 784.5 26.24 28.39 690.24 20 0.13732 0.523 Note: Limit of Power Density = F/1500 --- END --- 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 <Radio 1> + WLAN 5GHz <Radio 2> + + 3G/LTE <Radio 3> + 3G/LTE Modem = 0.21672 / 1 + 0.55951 / 1 + 0.02179 / 0.4665 + 0.02439 / 0.4665 = 0.87523 Therefore the maximum calculations of above situations are less than the “1” limit.
