2.RF Exposure Limit LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) FREQUENCY ELECTRIC FIELD MAGNETIC FIELD POWER DENSITY AVERAGE TIME RANGE (MHz) STRENGTH (V/m) STRENGTH (A/m) (mW/cm2) (minutes) LIMITS FOR GENERAL POPULATION / UNCONTROLLED EXPOSURE 300-1500 … … F/1500 30 1500-100,000 … … 1.0 30 F = Frequency in MHz 3.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 4.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. 5 Report No.: SA110711E01 Report Format Version 4.0.0.
