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 Antenna Connector Frequency range Antenna No. Brand Model Gain (dBi) Function Type Type (GHz to GHz) Ant. 1 (for WLAN 2.4GHz) 2.7 2.4~2.4835 TX/RX Ant. 2 (for BT) 0.12 2.4~2.4835 TX/RX Ant. 3 (for WLAN 5GHz) Microsoft NA PCB NA 2.2 5.15~5.85 TX/RX Chan (0) Ant. 4 (for WLAN 5GHz) 2.2 5.15~5.85 RX Chan (1) Report No.: SA150803E06D Page No. 5 / 6 Report Format Version: 6.1.1 Reference No.: 160830E03

2.5 Calculation Result For 2.4GHz, 5GHz (U-NII-1 & UNII-3) BT-EDR and BT-LE data was copied from the original test report (Report No.: SA150803E06) For WLAN Frequency Max Power Max Power Antenna Gain Distance Power Density Limit Band 2 2 (dBm) (mW) (dBi) (cm) (mW/cm ) (W/cm ) (MHz) 2412-2462 23.00 199.526 2.7 20 0.07391 1 5180-5240 16.00 39.811 2.2 20 0.01314 1 5260-5320 16.00 39.811 2.2 20 0.01314 1 5500-5700 19.00 79.433 2.2 20 0.02623 1 5745-5825 19.00 79.433 2.2 20 0.02623 1 For BT-EDR Frequency Max Power Max Power Antenna Gain Distance Power Density Limit Band 2 2 (dBm) (mW) (dBi) (cm) (mW/cm ) (W/cm ) (MHz) 2402-2480 10.50 11.22 0.12 20 0.00229 1 For BT-LE Frequency Max Power Max Power Antenna Gain Distance Power Density Limit Band 2 2 (dBm) (mW) (dBi) (cm) (mW/cm ) (W/cm ) (MHz) 2402-2480 10.50 11.22 0.12 20 0.00229 1 NOTE: 1. This power included tune-up tolerance range (1.5dB) that specified by manufacturer. 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 + BT = 0.07391 / 1 + 0.00229 / 1 = 0.0762 WLAN 5GHz + BT = 0.02623 / 1 + 0.00229 / 1 = 0.02852 Therefore the maximum calculations of above situations are less than the “1” limit. --- END --- Report No.: SA150803E06D Page No. 6 / 6 Report Format Version: 6.1.1 Reference No.: 160830E03
