1.      RF Exposure Evaluation

1.1.    Limits

        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        Electric Field       Magnetic Field   Power Density     Average Time
                                                                                2
               (MHz)          Strength (V/m)        Strength (A/m)     (mW/cm )          (Minutes)
                                (A) Limits for Occupational/ Control Exposures
             300-1500                --                    --           F/300                6
           1500-100,000              --                    --              5                 6
                           (B) Limits for General Population/ Uncontrolled Exposures
             300-1500                --                    --           F/1500               6
           1500-100,000              --                    --              1                 30
        F= Frequency in MHz


       Friis Formula
       Friis transmission formula: Pd = (Pout*G)/(4*pi*r2)


       Where
       Pd = power density in mW/cm2
       Pout = output power to antenna in mW
       G = gain of antenna in linear scale
       Pi = 3.1416
       R = distance between observation point and center of the radiator in cm


       Pd id the limit of MPE, 1 mW/cm2 . If we know the maximum gain of the antenna and the total
       power input to the antenna, through the calculation, we will know the distance r where the MPE
       limit is reached.



1.2.    Test Procedure

         Software provided by client enabled the EUT to transmit and receive data at lowest, middle
         and highest channel individually.
         The temperature and related humidity: 18℃and 78% RH.
