FCC ID: 2AWIZHL4GXVF RF Exposure Evaluation According to KDB447498D01 General RF Exposure Guidance v06 4.3.1. Standalone SAR test exclusion considerations Unless specifically required by the published RF exposure KDB procedures, standalone 1-g head or body and 10-g extremity SAR evaluation for general population exposure conditions, by measurement or numerical simulation, is not required when the corresponding SAR Exclusion Threshold condition, listed below, is satisfied. Limits According to FCC Part1.1310: 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 part1.1307(b) F= Frequency in MHz Friis Formula Friis transmission formula: Pd = (Pout*G)/(4* Pi * R 2) 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 id the limit of MPE . 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. Test Result of RF Exposure Evaluation 2.4GW IFI Antenna1& Antenna2 Gain: 2.0dBi, MIMO Gain:5.01dBi 5GW IFI Antenna1& Antenna2 Gain: 1.5dBi, MIMO Gain: 4.36dBi Antenna Gain: The maximum Gain measured in fully anechoic chamber is 1.0 in linear scale.

Remove the antenna from the EUT and then connect a low-loss RF cable from the antenna port to the spectrum analyzer. Set the spectrum analyzers RBW = approximately 1% of the emission bandwidth, VBW >RBW, Detector = Peak, Span>26dB bandwidth, and Sweep = auto ,Trace mode = max hold. Measure the maximum width of the emission that is 26dB down from the maximum of the emission. Compare this with the RBW setting of the analyzer. Readjust RBW and repeat measurement as needed until the RBW/EBW ratio is approximately 1%. Repeat until all the rest channels were investigated. 6.3 DEVIATION FROM STANDARD No deviation. 6.4 TEST SETUP 6.5 EUT OPERATION CONDITIONS The EUT tested system was configured as the statements of 2.4 Unless otherwise a special operating condition is specified in the follows during the testing. 6.6 TEST RESULT Temperature： 26°C Relative Humidity： 54% Pressure： 101kPa Test Voltage ： AC 120V Test Mode ： TX Project No.: ZKT-220929L7324-02 Page 91 of 133 U-NII-1 802.11 Mode Channel No. Frequency [MHz] 26dB Bandwidth [MHz] ANT1 ANT2 a 36 5180 19.30 19.48 40 5200 19.42 19.33 48 5240 19.21 19.28 n (20MHz) 36 5180 19.66 19.56 40 5200 19.79 19.59 48 5240 19.47 19.45 n (40MHz) 38 5190 39.07 38.85 46 5230 39.22 39.45 ac (20MHz) 36 5180 20.00 19.96 40 5200 19.74 19.86 48 5240 20.10 19.92 ac(40MHz) 38 5190 40.42 40.30 46 5230 40.37 40.49 ac(80MHz) 42 5210 80.25 80.14 ax (20MHz) 36 5180 21.82 21.98 40 5200 21.22 21.39 48 5240 21.92 21.76 ax(40MHz) 38 5190 39.43 39.35 46 5230 39.55 39.50 ax(80MHz) 42 5210 80.16 80.25 U-NII-3 802.11 Mode Channel No. Frequency [MHz] -6db Bandwidth [MHz] Limit ANT1 ANT2 a 149 5745 16.38 15.49 ≥ 500 kHz 157 5785 16.34 16.36 165 5825 16.31 16.40 n (20MHz) 149 5745 16.53 17.50 157 5785 15.69 16.62 165 5825 17.48 17.09 n (40MHz) 151 5755 33.93 35.15 159 5795 35.16 32.67 ac (20MHz) 149 5745 17.65 17.66 157 5785 17.69 17.69 165 5825 17.69 17.64 ac(40MHz) 151 5755 35.99 36.02 159 5795 36.17 35.85 ac(80MHz) 155 5775 76.14 76.41 ax (20MHz) 149 5745 19.11 19.07 157 5785 19.06 19.11 165 5825 19.04 19.08 ax(40MHz) 151 5755 38.05 38.14 159 5795 38.12 38.08 ax(80MHz) 155 5775 77.75 77.93 Test plot as follows: Project No.: ZKT-220929L7324-02 Page 92 of 133 U-NII-1 – 802.11a ANT1 ANT2 CH36-5180MHz CH36-5180MHz CH40-5200MHz CH40-5200MHz CH48-5240MHz CH48-5240MHz Project No.: ZKT-220929L7324-02 Page 93 of 133 U-NII-1 – 802.11n (20MHz) ANT1 ANT2 CH36-5180MHz CH36-5180MHz CH40-5200MHz CH40-5200MHz CH48-5240MHz CH48-5240MHz Project No.: ZKT-220929L7324-02 Page 94 of 133 U-NII-1 – 802.11n (40MHz) ANT1 ANT2 CH38-5190MHz CH38-5190MHz CH46-5230MHz CH46-5230MHz U-NII-1 – 802.11ac 20MHz) ANT1 ANT2 CH36-5180MHz CH36-5180MHz Project No.: ZKT-220929L7324-02 Page 95 of 133 CH40-5200MHz CH40-5200MHz CH48-5240MHz CH48-5240MHz U-NII-1 – 802.11ac (40MHz) ANT1 ANT2 CH38-5190MHz CH38-5190MHz Project No.: ZKT-220929L7324-02 Page 96 of 133 CH46-5230MHz CH46-5230MHz U-NII-1–802.11ac (80MHz) ANT1 ANT2 CH42 5210MHz CH42 5210MHz U-NII-1 – 802.11ax 20MHz) ANT1 ANT2 CH36-5180MHz CH36-5180MHz Project No.: ZKT-220929L7324-02 Page 97 of 133 CH40-5200MHz CH40-5200MHz CH48-5240MHz CH48-5240MHz U-NII-1 – 802.11ax (40MHz) ANT1 ANT2 CH38-5190MHz CH38-5190MHz Project No.: ZKT-220929L7324-02 Page 98 of 133 CH46-5230MHz CH46-5230MHz U-NII-1 –802.11ax (80MHz) ANT1 ANT2 CH42 5210MHz CH42 5210MHz U-NII-3 –802.11a ANT1 ANT2 CH149 -5745MHz CH149 -5745MHz Project No.: ZKT-220929L7324-02 Page 99 of 133 CH157 -5785MHz CH157 -5785MHz CH165 -5825MHz CH165 -5825MHz U-NII- 3 –802.11n (20MHz) ANT1 ANT2 CH149 -5745MHz CH149 -5745MHz Project No.: ZKT-220929L7324-02 Page 100 of 133 CH157 -5785MHz CH157 -5785MHz CH165 -5825MHz CH165 -5825MHz U-NII- 3 – 802.11n (40MHz) ANT1 ANT2 CH151 -5755MHz CH151 -5755MHz Project No.: ZKT-220929L7324-02 Page 101 of 133 CH159 -5795MHz CH159 -5795MHz U-NII-3 –802.11ac (20MHz) ANT1 ANT2 CH149 -5745MHz CH149 -5745MHz CH157 -5785MHz CH157 -5785MHz Project No.: ZKT-220929L7324-02 Page 102 of 133 CH165 -5825MHz CH165 -5825MHz U-NII- 3 – 802.11ac (40MHz) ANT1 ANT2 CH151 -5755MHz CH151 -5755MHz CH159 -5795MHz CH159 -5795MHz Project No.: ZKT-220929L7324-02 Page 103 of 133 U-NII-3– 802.11ac (80MHz) ANT1 ANT2 CH155 -5775MHz CH155 -5775MHz U-NII-3–802.11ax (20MHz) ANT1 ANT2 CH149 -5745MHz CH149 -5745MHz CH157 -5785MHz CH157 -5785MHz Project No.: ZKT-220929L7324-02 Page 104 of 133 CH165 -5825MHz CH165 -5825MHz U-NII- 3 – 802.11ax (40MHz) ANT1 ANT2 CH151 -5755MHz CH151 -5755MHz CH159 -5795MHz CH159 -5795MHz Project No.: ZKT-220929L7324-02 Page 105 of 133 U-NII- 3 – 802.11ax (80MHz) ANT1 ANT2 CH155 -5775MHz CH155 -5775MHz Project No.: ZKT-220929L7324-02 Page 106 of 133 7.
