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

2.2       MPE Calculation Method
The MPE was calculated at 25 cm to show compliance with the power density limit.
The following formula was used to calculate the Power Density:


               30  P  G                                                    E2
E (V/m) =                                Power Density:        Pd (W/m²) =
                   d                                                         377
E = Electric field (V/m)
P = RF output power (W)
G = EUT Antenna numeric gain (numeric)
d = Separation distance between radiator and human body (m)
The formula can be changed to

Pd =
        30  P  G
         377  d 2
