Report No.: 1902RSU013-U6 1. PRODUCT INFORMATION 1.1. Equipment Description Product Name: WIFI+BT Combo Module Model No.: AP6356S Brand Name: ASKEY Wi-Fi Specification 802.11a/b/g/n/ac Bluetooth Specification: V4.2 dual mode Power Type: VBAT: 3.3V DC; VDDIO: 1.8V DC 1.2. Description of Available Antennas Antenna Type Frequency TX Per Chain Max Antenna Directional Gain Band Paths Gain (dBi) (dBi) (GHz) Ant 0 Ant 1 For Power For PSD Wi-Fi Internal Antenna 2412 ~ 2462 2 2.48 3.52 3.52 6.53 PCB 5150 ~ 5825 2 5.12 4.85 5.12 8.13 Bluetooth Internal Antenna PCB 2402 ~ 2480 1 2.48 -- Note: 1. The EUT supports Cyclic Delay Diversity (CDD) technology on 802.11a/b/g mode, and CDD signals are correlated. For CDD transmissions, directional gain is calculated as follows, NANT = 2, NSS = 1. If all antennas have the same gain, GANT, Directional gain = GANT + Array Gain, where Array Gain is as follows.  For power spectral density (PSD) measurements on all devices, Array Gain = 10 log (NANT/ NSS) dB = 3.01;  For power measurements on IEEE 802.11 devices, Array Gain = 0 dB for NANT ≤ 4; If antenna gains are not equal, Directional gain may be calculated by using the formulas applicable to equal gain antennas with GANT set equal to the gain of the antenna having the highest gain. 2. The EUT supports Beam Forming technology on 802.11n/ac mode, Directional gain = GANT + 10 log (NANT/NSS) dBi, where NSS = the number of independent spatial streams of data and GANT is the antenna gain in dBi.

Report No.: 1902RSU013-U6 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.: 1902RSU013-U6 2.2. Test Result of RF Exposure Evaluation Product WIFI+BT Combo 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 12.29 0.0034 1 2412 ~ 2462 20.27 0.0212 1 Wi-Fi 5180 ~ 5825 22.69 0.0370 1 CONCLUSION: The max Power Density at R (20 cm) = 0.0034mW/cm2 + 0.0212 mW/cm2 + 0.0370 mW/cm2 = 0.0616 mW/cm2 < 1 mW/cm2. Therefore, the Min Safety Distance is 20cm. The End FCC ID: H8N-AP6356S Page Number: 7 of 8 IC: 1353A-AP6356S
