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 2 1.34-30 824/f 2.19/f (180/f )* 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 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 37cm away from the body of the user. So, this device is classified as Mobile Device. Report No.: SA180109C12A Page No. 5 / 6 Report Format Version: 6.1.1 Reference No.: 180109C13

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) CDD Mode 2412-2462 29.52 9.45 37 0.459 1 5180-5240 29.79 9.02 37 0.442 1 5250-5350 23.91 9.15 37 0.118 1 5470-5725 23.73 9.50 37 0.122 1 5745-5825 29.53 9.74 37 0.491 1 Beamforming Mode 2412-2462 23.99 9.45 37 0.128 1 5180-5240 25.11 9.02 37 0.150 1 5250-5350 19.41 9.15 37 0.042 1 5470-5725 19.23 9.50 37 0.043 1 5745-5825 25.01 9.74 37 0.174 1 Note: For 2412-2462MHz: Directional gain = 10 log[(10G1 /20 + 10G2 /20 + ... + 10GN /20)2/4]= 9.45dBi For 5180-5240MHz: Directional gain = 10 log[(10G1 /20 + 10G2 /20 + ... + 10GN /20)2/4]= 9.02dBi For 5250-5350MHz: Directional gain = 10 log[(10G1 /20 + 10G2 /20 + ... + 10GN /20)2/4]= 9.15dBi For 5470-5725MHz: Directional gain = 10 log[(10G1 /20 + 10G2 /20 + ... + 10GN /20)2/4]= 9.50dBi For 5745-5825MHz: Directional gain = 10 log[(10G1 /20 + 10G2 /20 + ... + 10GN /20)2/4]= 9.74dBi Conclusion: 2.4GHz & 5GHz can transmit at same time. 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 = 0.459 + 0.491 = 0.950 Therefore the maximum calculations of above situations are less than the “1” limit. ---END--- Report No.: SA180109C12A Page No. 6 / 6 Report Format Version: 6.1.1 Reference No.: 180109C13
