MPE Calculation Method
The MPE was calculated at 20 cm to show compliance with the power density limit. The following formula was used to calculate the Power Density:
E (V/m) = √(30 × P × G) / d
Power Density: Pd (W/m²) = E² / 377
Where:
- 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 × d²)
