FCC ID:2BSAY-SN-MD150AS RF EXPOSURE EVALUATION 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(MHz) Electric Field Strength(V/m) Magnetic Field Strength(A/m) Power Density(mW/cm 2 ) Average Time (A) Limits for Occupational/Control Exposures 300-1500 -- -- F/300 6 1500- 100000 -- -- 5 6 (B) Limits for General Population/Uncontrol Exposures 300-1500 -- -- F/1500 6 1500- 100000 -- -- 1 30 11.1 Friis transmission formula: Pd= (Pout*G)\ (4*pi*R 2 ) Where Pd= Power density in mW/cm 2 Pout=output power to antenna in mW G= Numeric gain of the antenna relative to isotropic antenna Pi=3.1416 R= distance between observation point and center of the radiator in cm Pd the limit of MPE, 1mW/cm 2 ,If we know the maximum gain of the nd total power input to the antenna, through the calculation, we will know the distance where the MPE limit is reached. RF Exposure Information: The radiated output power of this device meets the limits of FCC/IC radio frequency exposure limits.This device should be operated with a minimum separation distance of 20cm between the equipment and a person's body. 11.2 Measurement Result WIFI 2.4G Antenna :3.20dBi Measured power (dBm) Tune-up power (dBm) Max tune- up power (dBm) Antenna Gain Numeric Evaluation result (mW/cm2 ) Power density Limits (mW/cm2 ) 15.16 14 to 16 16 2.09 0.0166 1 WIFI 5G Antenna :4.34dBi Measured power (dBm) Tune-up power (dBm) Max tune- up power (dBm) Antenna Gain Numeric Evaluation result (mW/cm2 ) Power density Limits (mW/cm2 ) 12.50 11 to 13 13 2.72 0.0108 1 433.92MHz Main Power：81.32dBμV/m=81.32-95.2=-13.88dBm 30MHz-1G:-13.88+4.7=-9.18dBm Measured power (dBm) Tune-up power (dBm) Max tune- up power (dBm) Antenna Gain Numeric Evaluation result (mW/cm2 ) Power density Limits (mW/cm2 ) -9.18 -11 to -9 -9 NA 0.0001 1 CONCLUSION of simultaneous transmitter The module can transmit simultaneously, the formula of calculated the MPE is: CPD1/LPD1+CPD2/LPD2+......etc. < 1 CPD = Calculation power density LPD = Limit of power density Therefore the worst-case situation is 0.0166/1.00+0.0108/1.00+0.0001/1.00=0.0275which is less than “1”, This confirmed that the device comply with FCC 1.1310 MPE limit.
