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 radiator
        R = distance to the center of radiation of the antenna

Note:
The EUT incorporates a MIMO function. Physically, the EUT provides three completed
transmitters and receivers (3T3R), all transmit signals are completely uncorrelated, then,
Direction gain = GANT, that is Directional gain=3.
