f = frequency in MHz *Plane-wave equivalent power density

NOTE: General population/uncontrolled exposures apply in situations in which
the general 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 can not exercise control over their exposure.

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

1.3 MPE Calculation Method

S = PG/(4πR2)
0.5
R = [PG/(4πS)]

where: S = power density (in appropriate units, e.g. mW/ cm2)
P = power input to the antenna (in appropriate units, e.g., mW)
(the measured power value see Report: F12124 Section 6.6)
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)
