2 RF Exposure 2.1 Limits for Maximum Permissible Exposure (MPE) Frequency Range Electric Field Magnetic Field Power Density Average Time 2 (MHz) Strength (V/m) Strength (A/m) (mW/cm ) (minutes) Limits For General Population / Uncontrolled Exposure 0.3-1.34 614 1.63 (100)* 30 2 1.34-30 824/f 2.19/f (180/f )* 30 30-300 27.5 0.073 0.2 30 300-1500 … … f/1500 30 1500-100,000 … … 1.0 30 f = Frequency in MHz ; *Plane-wave equivalent power density 2.2 MPE Calculation Formula 2 Pd = (Pout*G) / (4*pi*r ) where 2 Pd = power density in mW/cm 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.

2.4 Calculation Result For 24GHz: Field Strength of Power Frequency Fundamental Pout EIRP Pout EIRP Distance Limit Density 2 (MHz) (dBm) (mW) (cm) 2 (mW/cm ) (dBuV/m) (mW/cm ) 24145 105.1 10.07 10.162 20 0.00202 1 Field strength is then converted to EIRP as follows: (i) EIRP = ((E*d)^2) / 30 where: E is the field strength in V/m; d is the measurement distance in meters; EIRP is the equivalent isotropically radiated power in watts. (ii) Working in dB units, the above equation is equivalent to: EIRP[dBm] = E[dBμV/m] + 20log(d[meters]) - 104.77 (iii) Or, if d is 3 meters: EIRP[dBm] = E[dBμV/m] – 95.23 --- END --- Report No.: SA180123D04A Page No. 6 / 6 Report Format Version: 6.1.1 Reference No.: 180209D09
