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 1.34-30 824/f 2.19/f (180/f2)* 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 20 cm away from the body of the user. So, this device is classified as Mobile Device. 2.4 Antenna Gain Frequency 5500 5600 5700 5745 5785 5825 Antenna Antenna (MHz) Directional Antenna Gain (dBi) Type Connector XZ 4.27 XZ 4.27 XZ 4.47 XZ 4.69 XZ 4.84 XZ 4.79 Vertical-Pol YZ 3.35 YZ 2.70 YZ 2.73 YZ 2.93 YZ 2.60 YZ 2.49 PCB i-pex(MHF) XY 3.24 XY 3.58 XY 4.02 XY 4.12 XY 4.08 XY 4.20 XZ 4.53 XZ 4.44 XZ 4.34 XZ 4.41 XZ 4.67 XZ 4.36 Horizontal-pol YZ 2.19 YZ 1.56 YZ 1.39 YZ 1.24 YZ 1.43 YZ 1.51 PCB i-pex(MHF) XY 4.47 XY 4.82 XY 4.89 XY 4.94 XY 5.09 XY 4.73 Note: More detailed information, please refer to operating description.

2.5 Calculation Result of Maximum Conducted Power For 5GHz (U-NII-2C band) the Maximum power was refer to the FCC test report (Report No.: RF190319E02B-1) For 5GHz (U-NII-3 band) data was copied from the original test report (Report No.: SA190319E02) Evaluation Operation Max Power Antenna Gain Distance Power Density Limit Frequency Mode (mW) (dBi) (cm) (mW/cm2) (mW/cm2) (MHz) WLAN 5610 248.291 4.89 20 0.15230 1 (U-NII-2C) WLAN 5795 992.471 5.09 20 0.63745 1 (U-NII-3) Note: 1. Determining compliance based on the results of the compliance measurement, not taking into account measurement instrumentation uncertainty. 2. 5GHz (U-NII-2C): The directional gain = 4.89dBi 5GHz (U-NII-3): The directional gain = 5.09dBi 3. The Max. Power = Max. tune up power including tolerance declared by client. --- END --- Report No.: SA190319E02C Page No. 6 / 6 Report Format Version: 6.1.1 Reference No.: 190528E05
