1.1. MAXIMUM PERMISSABLE EXPOSURE

Calculations for Maximum Permissible Exposure Levels
Power Density = Pd (mW/cm2) = EIRP/(4*π*d2)
EIRP = P * G
P = Peak output power (mW)
G = Antenna numeric gain (numeric)
d = Separation distance (cm)
Numeric Gain = 10 ^ (G (dBi)/10)

Because the EUT belongs to the General Population/Uncontrolled Exposure the limit of power density is
f/1500 mW/cm2

These calculations represent worst case in terms of the exposure levels.
                                                                     Calculated

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