f = Frequency in MHz ; *Plane-wave equivalent power density



2.2     MPE Calculation Formula

Pd = (Pout*G) / (4*pi*r2)
where
Pd = power density in mW/cm 2
Pout = output power to antenna in mW
G = gain of antenna in linear scale
Pi = 3.1416
R = distance between observation point and center of the radiator in cm

Conclusion:
The formula of calculated the MPE is:
CPD1 / LPD1 + CPD2 / LPD2 + ……etc. < 1
CPD = Calculation power density
LPD = Limit of power density


WLAN 5GHz (UNII-3) + Bluetooth + WiGig 60GHz = 0.18355 / 1 + 0.00049 / 1 + 0.73074 / 1 + 0.000003 / 1 +
0.000003 / 1 = 0.91479

Therefore the maximum calculations of above situations are less than the “1” limit.
