  2. 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

      Ant.            Brand           Model Name         Antenna Type     Connector       Gain (dBi)
       1               N/A                 N/A              Dipole            N/A             4

       2               N/A                 N/A              Dipole            N/A             4
     Note:
         The EUT incorporates a MIMO function. Physically, the EUT provides two completed
          transmitters and receivers (2T2R), all transmit signals are completely correlated, then,
           Direction gain = GANT+10log(N)dBi=4+10log(2), that is Directional gain=7.01.
           So, the out power limit is 30-7.01+6=28.99,
           the power density limit is 8-7.01+6=6.99.
