  MPE CALCULATION METHOD:
               Calculation Method of RF Safety Distance:




           where:
           S = power density
           P = power input to the antenna
           G = power gain of the antenna in the direction of interest relative to an isotropic radia
           R = distance to the center of radiation of the antenna

So for 2.4G+5G simultaneous transmission MPE:

                 0.3326/1+0.0519/1=0.3845<1



Note: the calculation distance is 20cm.
