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 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.: SA160719C17C Page No. 5 / 6 Report Format Version: 6.1.1 Reference No.: 160719C17, 161017C01

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) WLAN 2.4GHz: CDD mode 2412-2462 23.44 7.01 20 0.221 1 WLAN 2.4GHz: Beamforming mode 2412-2462 21.48 7.01 20 0.141 1 WLAN 5GHz: CDD mode 5180-5240 23.05 8.87 20 0.310 1 5745-5825 22.92 8.87 20 0.300 1 WLAN 5GHz: Beamforming mode 5180-5240 22.86 8.87 20 0.296 1 5745-5825 23.12 8.87 20 0.315 1 BT LE 2402-2480 2.95 3.51 20 0.001 1 Zigbee 2405-2480 3.25 3.51 20 0.001 1 Note: 2.4GHz Band: Directional gain = 10 log[(10G1 /20 + 10G2 /20 + ... + 10GN /20)2/2]= 7.01dBi 5GHz Band: Directional gain = 10 log[(10G1 /20 + 10G2 /20 + ... + 10GN /20)2/2]= 8.87 dBi Max Power (dBm) Total Power Power Limit Frequency Band WLAN BT LE Zigbee (dBm) (dBm) 2.4GHz 23.44 2.95 - 23.48 30 2.4GHz 23.44 - 3.25 23.48 30 Conclusion: 2.4GHz & 5GHz & BT LE or 2.4GHz & 5GHz & Zigbee technology can transmit at same time. BT LE and Zigbee cannot transmit simultaneously. The formula of calculated the MPE is: CPD1 / LPD1 + CPD2 / LPD2 + ……etc. < 1 CPD = Calculation power density LPD = Limit of power density 1. WALN 2.4GHz + WALN 5GHz + BT LE = 0.221 + 0.315 + 0.001 = 0.537 2. WALN 2.4GHz + WALN 5GHz + Zigbee = 0.221 + 0.315 + 0.001 = 0.537 Therefore the maximum calculations of above situations are less than the “1” limit. ---END--- Report No.: SA160719C17C Page No. 6 / 6 Report Format Version: 6.1.1 Reference No.: 160719C17, 161017C01
