Report No.: 1705RSU01203 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.: 1705RSU01203 2.2. Test Result of RF Exposure Evaluation Product Cassia Bluetooth Router Test Item RF Exposure Evaluation Antenna Gain: Refer to Clause 1.2 of antenna description. Test Mode Frequency Band Maximum Average Power Density at Limit (MHz) Output Power R = 20 cm (mW/cm2) (dBm) (mW/cm2) Wi-Fi 2412 ~ 2462 11.00 0.0044 1 Bluetooth 2402 ~ 2480 12.00 0.0177 1 Note: The maximum average output power refers to the operation description which is declared by the manufacturer. CONCULISON: Both of the WLAN 2.4GHz Band and Bluetooth 2.4GHz Band can transmit simultaneously. Therefore, the Max Power Density at R (20 cm) = 0.0044mW/cm2 + 0.0177mW/cm2 = 0.0221mW/cm2 < 1mW/cm2. So the EUT complies with the requirement. The End FCC ID: 2ALGLX1000 Page Number: 5 of 5
