Determine the maximum power density for the general / uncontrolled population minimum separation distance of 20 cm. The power density is calculated as: Pd = power density in mW/cm2 Pt  G Pt = transmit power in milliwatts Pd  4  r2 G = numeric antenna gain r = distance between body and transmitter in centimeters.
