MPE Calculation

The Power Density (mW/cm2) is calculated as follows:

PG
S=
4πR 2
Where:

S = power density (in appropriate units, e.g. mW/cm2)
P = power input to the antenna (in appropriate units, e.g., mW)
G = power gain of the antenna in the direction of interest relative to an isotropic radiator
R = distance to the center of radiation of the antenna (appropriate units, e.g., cm)

Installation Guidelines
The installation manual contains the following text advising how to install the equipment to maintain
compliance with the FCC RF exposure requirements:

“RF Exposure (Intentional Radiators Only)
This equipment complies with the FCC RF radiation requirements for uncontrolled environments. To
maintain compliance with these requirements, the antenna and any radiating elements should be installed
to ensure that a minimum separation distance of 20 cm is maintained from the general population.

Conclusion
This device complies with the MPE requirements by providing adequate separation between the device,
any radiating structure and the general population.
