RF Exposure Info

FCC ID : 2AXH6-CR-M4 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. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body. 11.2 Measurement Result WIFI2.4G Antenna gain: 2.27 dBi Measured power (dBm) Tune-up power (dBm) Max tune-up power (dBm) Antenna Gain Numeric Evaluation result (mW/cm2 ) Power density Limits (mW/cm2 ) 16.52 15 to 17 17 1.69 0.0168 1 BLE Antenna gain: 2.21 dBi CONCLUSION of simultaneous transmitter Both of the module 1 and module 2 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 0.0168 /1.00+0.0002 /1.00 = 0.0170, which is less than “1”, This confirmed that the device comply with FCC 1.1310 MPE limit. Measured power (dBm) Tune-up power (dBm) Max tune-up power (dBm) Antenna Gain Numeric Evaluation result (mW/cm2 ) Power density Limits (mW/cm2 ) -2.52 -4 to -2 -2 1.66 0.0002 1
