May 28, 2008 Maximum Permissible Exposure FCC, Part 15 Subpart C §15.407(f) Industry Canada RSS-Gen §5.5 Calculations for Maximum Permissible Exposure Levels Power Density = Pd (mW/cm2) = EIRP/(4πd2) EIRP = P * G * 3 P = Peak output power (mW) G = Antenna numeric gain (numeric) d = Separation distance (cm) Numeric Gain = 10 ^ (G (dBi)/10) The Aruba AP-120/121 has three transmitters. The peak power in the table below is calculated by assuming a worst case scenario where the three transmitters are operating simultaneously in the same band. The Peak Power in mW is calculated by taking the maximum conducted power measured in each band and multiplying by 3. Because the EUT belongs to the General Population/Uncontrolled Exposure the limit of power density is 1.0 mW/cm2 Calculated Peak Peak Minimum Numeric Safe Freq. Band Antenna Output Output Separation Gain Distance @ (MHz) Gain (dBi) Power Power Distance (numeric) 1mW/cm2 (dBm) (mW) (cm) Limit(cm) 5150 - 5250 14.0 25.12 +14.93 93.35 13.66 20 5250 - 5350 14.0 25.12 +14.52 84.95 13.03 20 5470 - 5725 14.0 25.12 +15.95 118.07 15.37 20 Note: for mobile or fixed location transmitters the minimum separation distance is 20cm, even if calculations indicate the MPE distance to be less. Specification Maximum Permissible Exposure Limits FCC §1.1310 Limit = 1mW / cm2 from 1.310 Table 1 RSS-Gen §5.5 Before equipment certification is granted, the application requirements of RSS-102 shall be met. 440 Boulder Court, Suite 200, Pleasanton, California 94566, USA Tel.: +1 925 462 0304, Fax: +1 925 462 0306 www.micomlabs.com
