** MPE Calculations **
The EUT will only be used with a separation of 20 centimeters or greater between the antenna and
the body of the user. The MPE calculation for this exposure is shown below.

Power density at the specific separation:

Where,
SWLAN = PG/(4R2π)
S = Maximum power density (mW/cm2)

SWLAN = (80 * 1) / (4 * 202 * π) P = Power input to the antenna (mW)
G = Numeric power gain of the antenna
SWLAN = 0.0076 mW/cm2 R = Distance to the center of the radiation of the antenna
(20cm = limit for MPE)

The Maximum permissible exposure (MPE) for the general population is 1 mW/cm2 .
The power density at 20cm does not exceed the 1 mW/cm2 limit.
Therefore, the exposure condition is compliant with FCC rules.
