FCC ID:2AT8P-WS-SR-US-T 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 2.4G- WIFI ANT: 1.37dBi; Antenna Gain: The maximum Gain measured in fully anechoic chamber is 1.0 in linear scale. Output Power Into Antenna & RF Exposure Evaluation Distance: 20cm Measurement Data The Max Conducted Peak Output Power data refer to report Report No.:ZKT-221212L9259-1/ZKT-221212L9259-2 1.1 EUT RF EXPOSURE Operational Mode: BLE (GFSK worst case) Channel Maximum Peak Conducted Output Power (dBm) Tune up tolerance (dB) Maximum tune-up Power Calculated value (mW/cm2) Exclusion threshold (dBm) (mW) 2440 MHz 8.37 8±1 9 7.943 0.00217 1 Conclusion: the calculated value ≤1.0, SAR is exempted. Remark: Pd = (Pout*G)/(4* Pi * R 2 )=( 7.943*1.371)/(4*3.1415*20*20)= 0.00217, G=10 gain/10 =1.371 Operational Mode: 802.11b Channel Maximum Peak Conducted Output Power (dBm) Tune up tolerance (dB) Maximum tune-up Power Calculated value Exclusion threshold (dBm) (mW) 2437 MHz 18.65 18±1 19 79.433 0.0217 1 Conclusion: the calculated value ≤1.0, SAR is exempted. Remark: Pd = (Pout*G)/(4* Pi * R 2 )=( 7.943*1.371)/(4*3.1415*20*20)= 0.00217, G=10 gain/10 =1.371 EUT RF Exposure Evaluation simultaneous transmission operations According to 865664D02 2.2 d) 1): The sum of the ratios of the spatially averaged results to the applicable frequency dependent MPE limits : Simultaneous transmission mode The sum of the ratios SUM Limit BLE+2.4G WIFI 0.00217+0.0217 0.02387 1.0 conclusion : 0.02387< 3.0, So there is no sar requirement
