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. 3 Antenna Gain The antennas provided to the EUT, please refer to the following table: BT Antenna Connecter Frequency range Brand Model Gain (dBi) Type Type (GHz to GHz) NA NA -1.29 PCB printed NA 2.402 ~ 2.48 WLAN Antenna Connecter Frequency range Brand Model Gain (dBi) Type Type (GHz to GHz) 1.64 2.4 ~ 2.4835 NA NA PCB printed NA 1.57 5.15 ~ 5.85 Report No.: SA141203E08A Page No. 5 / 7 Report Format Version: 6.1.1 Reference No.:141203E09

For Bluetooth: GFSK CONDUCTED ANTENNA POWER FREQUENCY DISTANCE LIMIT POWER GAIN DENSITY (MHz) (cm) (mW/cm2) (mW) (dBi) (mW/cm2) 2402-2480 1.905 -1.29 20 0.00028 1 8DPSK CONDUCTED ANTENNA POWER FREQUENCY DISTANCE LIMIT POWER GAIN DENSITY (MHz) (cm) (mW/cm2) (mW) (dBi) (mW/cm2) 2402-2480 1.279 -1.29 20 0.00019 1 BT-LE (GFSK) CONDUCTED ANTENNA POWER FREQUENCY DISTANCE LIMIT POWER GAIN DENSITY (MHz) (cm) (mW/cm2) (mW) (dBi) (mW/cm2) 2402-2480 2.075 -1.29 20 0.00016 1 Conclusion: Both of the Bluetooth and WLAN can transmit simultaneously, the formula of calculated the MPE is: CPD1 / LPD1 + CPD2 / LPD2 + ……etc. < 1 CPD = Calculation power density LPD = Limit of power density Therefore, the worst-case situation is 0.08846 / 1 + 0.00028 / 1 = 0.089, which is less than “1”. This confirmed that the device comply with FCC 1.1310 MPE limit. --- END --- Report No.: SA141203E08A Page No. 7 / 7 Report Format Version: 6.1.1 Reference No.:141203E09
