Report No.: 1710WSU01606 2. RF Exposure Evaluation 2.1. Limits According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environment impact of human exposure to radio frequency (RF) radiation as specified in 1.1307(b) 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) (A) Limits for Occupational/ Control Exposures 300-1500 -- -- f/300 6 1500-100,000 -- -- 5 6 (B) Limits for General Population/ Uncontrolled Exposures 300-1500 -- -- f/1500 6 1500-100,000 -- -- 1 30 f= Frequency in MHz 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 Pd is the limit of MPE, 1mW/cm². If we know the maximum gain of the antenna and the total power input to the antenna, through the calculation, we will know the distance r where the MPE limit is reached.

Report No.: 1710WSU01606 2.2. Test Result of RF Exposure Evaluation Product W-LAN + Bluetooth Module Test Item RF Exposure Evaluation Test Mode Frequency Band Maximum EIRP Power Density at Limit (MHz) (dBm) R = 20 cm (mW/cm2) (mW/cm2) Bluetooth 2402 ~ 2480 15.35 0.0068 1 802.11b/g/n 2412 ~ 2462 21.85 0.0305 1 802.11a/n/ac 5180 ~ 5825 17.23 0.0105 1 CONCULISON: The max Power Density at R (20 cm) = 0.0068mW/cm2 < 1 mW/cm2 for Bluetooth. The max Power Density at R (20 cm) = 0.0305mW/cm2 < 1 mW/cm2 for 2.4G WLAN. The max Power Density at R (20 cm) = 0.0105mW/cm2 < 1 mW/cm2 for 5G WLAN. Therefore, the Min Safety Distance is 20cm.
