Calculations for Maximum Permissible Exposure Levels

       Power Density = Pd (mW/cm2) = EIRP/(4πd2)
       EIRP = P * G
       P = Peak output power (mW)
       G = Antenna numeric gain (numeric)
       d = Separation distance (cm)
       Numeric Gain = 10 ^ (G (dBi)/10)
The peak power in the table below is calculated by assuming a worst case scenario
where all of the EUT transmitters are operating simultaneously in the same band. The
Peak Power in mW is the highest transmitter power measured and summed across all
transmitters.

Because the EUT belongs to the General Population/Uncontrolled Exposure the limit of
power density is 1.0 mW/cm2

                                                                             Calculated

*Note: for mobile or fixed location transmitters the minimum separation distance is 20cm,
even if calculations indicate the MPE distance to be less.

Specification
