Declaration of Conformity for RF Exposure
This microwave outdoor unit product has been found to be compliant to the
requirements set forth in CFR 47Section 1.1307 addressing RF Exposure from radio
frequency devices as defined in Evaluating Compliance with FCC Guidelines for
Human Exposure to Radio Frequency Electromagnetic Fields.
Antennas with less than 23.5 dBi gain should be located at a minimum of 39.03 cm in
more from the body of all persons.
Calculation Formula: P
d
= (P
out
*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 is the limit of MPE, 1mW/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.
