public may be exposed, or in which persons that are exposed as a consequence of their
employment may not be fully aware of the potential for exposure or cannot exercise control over
their exposure.

Note 3: The limit value 1.0mW/cm2 is available for this EUT.



MPE CALCULATION METHOD

             2
S =PG/(4πR )

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)
