FCC ID: 2AMZYNOH2O 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 antenna and total power input to the antenna, through the calculation, we will know the distance where the MPE limit is reached. mW = 10^( dBm/10) 11.2 Measurement Result Operation Frequency: 2402MHz-2480MHz; Antenna gain: -0.58dBi; R=20cm EDR Channel Freq.
