5          RF Exposure Evaluation
5.1       RF Exposure Compliance Requirement
5.1.1 Limits
          According to FCC Part1.1310: 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 part1.1307(b)




F= Frequency in MHz
Friis Formula
Friis transmission formula: Pd = (Pout*G)/(4* Pi * R 2)
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.

5.1.2 Test Procedure
