- Page 3 of 4 - Report No.: MTi190531E195 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) MPE Calculation Method Friis transmission formula: Pd= (Pout*G)\ (4*pi*R2) Where Pd= Power density in mW/cm2 Pout=output power to antenna in mW G= Numeric gain of the antenna relative to isotropic antenna Pi=3.1415926 R= distance between observation point and center of the radiator in cm(20cm) Pd the limit of MPE, 1mW/cm2. 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.
