2.1 Limits for Maximum Permissible Exposure (MPE)
  Frequency Range      Electric Field   Magnetic Field              Power Density          Average Time
       (MHz)          Strength (V/m)    Strength (A/m)                (mW/cm2)               (minutes)
                          Limits For General Population / Uncontrolled Exposure

      300-1500                 …                      …                   F/1500                  30

F = Frequency in MHz

2.2 MPE Calculation Formula
Pd = (Pout*G) / (4*pi*r2)
where
Pd = power density in mW/cm2
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

2.3 Classification
The antenna of this product, under normal use condition, is at least 20cm away from the body of the user. So,
this device is classified as Mobile Device.

CPD1 / LPD1 + CPD2 / LPD2 + ……etc. < 1
CPD = Calculation power density
LPD = Limit of power density

Max. WLAN + WWAN = 0.147/1 + 0.158/0.520 = 0.147 + 0.304 = 0.451 < 1
