MPE CALCULATION METHOD

Calculation Method of RF Safety Distance:

S = (P * G) / (4 * π * R²) = EIRP / (4 * π * R²)

where:

S = power density
P = power input to the antenna
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
