Custom EMC Test Report No: EDCS — 1470239 olllillh C1§560 Maximum Permissible Exposure (MPE) Calculations For AIR—CAP1572xxx—x—K9 Devices are subject to the radio frequency radiation exposure requirements specified in Sec. 1.1307(b), Sec. 2.1091 and Sec. 2.1093 of this chapter, as appropriate. All equipment shall be considered to operate in a general population/uncontrolled" environment. Applications for equipment authorization of devices operating under this section must contain a statement confirming compliance with these requirements for both fundamental emissions and unwanted emissions. Technical information showing the basis for this statement must be submitted to the Commission upon request. Given E=~(30*P*G)/d and S=EA2/3770 where E=Field Strength in Volts/meter P=Power in Watts G=Numeric Antenna Gain d=Distance in meters S=Power Density in mW/cmA2 Combine equations and rearrange the terms to express the distance as a function of the remaining variables: d=((30*P*G)/(3770*S)) Changing to units of power in mW and distance in cm, using: P(mW)=P(W)/1000 d(cm)=100*d(m) yields d=100*\/((30*(P/1000)*G)/(3770*S)) d=0.282*~(P*G/S) where d=Distance in cm P=Power in mW G=Numerica Antenna Gain S=Power Density in mW/cm*A2 Substituting the logarithmic form of power and gain using: P(mW)=10M(P(dBm)/10} G{numeric)=104(G({(dBi)/10) yields d=0.282*104((P+G)}/20)NS Equation (1) and s=((0.282*104((P+G)/20))/d)42 Equation (2) where d=MPE distance in cm P=Power in dBm G=Antenna Gain in dBi S=Power Density in mW/cm*A2

Note that for mobile or fixed location transmitters such as an access point, the minimum separation distance is 20 cm even if the calculations indicate that the MPE distance may be less. S=1mW/ecmA2 maximum. Using the peak power levels recorded in the test report along with Equation 1 above, the MPE distances are calculated as follows.
