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; *Plane-wave equivalent power density 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.: SA180914C09 Page No. 5 / 7 Report Format Version: 6.1.1

3 Calculation Result of Maximum Tune up Power For WLAN: (Base on WLAN module report (Model: WLE600VX, FCC ID: TK4WLE600VX)) Power Frequency Band Max Power Antenna Gain Distance Limit TX Funtion Density (MHz) (dBm) (dBi) (cm) (mW/cm2) (mW/cm2) WLAN: 1TX 22.26 1.60 20 0.048 1 2.4GHz Band 2TX 24.22 4.61 20 0.152 1 WLAN: 1TX 21.89 1.94 20 0.048 1 5GHz Band 2TX 24.63 4.95 20 0.181 1 Note: 2.4GHz: Directional gain = 1.60dBi + 10log(2) = 4.61dBi 5GHz: Directional gain = 1.94dBi + 10log(2) = 4.95dBi For WWAN: (Base on WWAN module report (Model: EM7455, FCC ID: N7NEM7455)) Frequency Power Max Power Antenna Gain Distance Limit Function Band Density (dBm) (dBi) (cm) (mW/cm2) (MHz) (mW/cm2) WCDMA Band 2 1852.4-1907.6 26.84 1.56 20 0.138 1 WCDMA Band 4 1712.4-1752.6 26.62 1.62 20 0.133 1 WCDMA Band 5 826.4-846.6 26.74 3.20 20 0.196 0.551 LTE Band 4 1710.7-1754.3 28.94 1.62 20 0.226 1 LTE Band 7 2622.5-2687.5 27.72 0.44 20 0.130 1 LTE Band 12 699.7-715.3 28.98 1.49 20 0.222 0.466 LTE Band 13 779.5-784.5 28.79 1.66 20 0.221 0.520 LTE Band 25 1850.7-1914.3 28.83 1.56 20 0.218 1 LTE Band 26 824.7-848.3 29.06 3.20 20 0.335 0.550 LTE Band 30 2307.5-2312.5 27.98 2.27 20 0.211 1 LTE Band 41 2537.5-2652.5 27.83 0.44 20 0.134 1 Report No.: SA180914C09 Page No. 6 / 7 Report Format Version: 6.1.1

Conclusion: The formula of calculated the MPE is: CPD1 / LPD1 + CPD2 / LPD2 + ……etc. < 1 CPD = Calculation power density LPD = Limit of power density 1. WLAN 2.4G+ WWAN LTE Band 4 = 0.152 / 1 + 0.226 / 1 = 0.378 2. WLAN 5.0G+ WWAN LTE Band 4 = 0.181 / 1 + 0.226 / 1 = 0.407 3. WLAN 2.4G+ WWAN LTE Band 25 = 0.152 / 1 + 0.218 / 1 = 0.370 4. WLAN 5.0G+ WWAN LTE Band 25 = 0.181 / 1 + 0.218 / 1 = 0.399 5. WLAN 2.4G+ WWAN LTE Band 26 = 0.152 / 1 + 0.335 / 0.550 = 0.761 6. WLAN 5.0G+ WWAN LTE Band 26 = 0.181 / 1 + 0.335 / 0.550 = 0.791 Therefore the maximum calculations of above situations are less than the “1” limit. ---END--- Report No.: SA180914C09 Page No. 7 / 7 Report Format Version: 6.1.1
