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)
In accordance with FCC requirements of human exposure to radiofrequency fields, the radiating element
shall be installed such that a minimum separation distance of 20cm 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.
