ARUB170-1 Maximum Permissible Exposure FCC, Part 15 §1.1310 Industry Canada RSS-Gen §5.6 Calculations for Maximum Permissible Exposure Levels Power Density = Pd (mW/cm2) = EIRP/(4πd2) EIRP = P * G P = Peak output power (mW) G = Antenna numeric gain (numeric) d = Separation distance (cm) Numeric Gain = 10 ^ (G (dBi)/10) Because the EUT belongs to the General Population/Uncontrolled Exposure the limit of power density is 1.0 mW/cm2 The calculations in the table below use highest gain antennas for the client EUT. Where the antenna gain exceeds 6dBi the transmitter power is reduced where necessary to meet the EIRP requirements. These calculations represent worst case in terms of the exposure levels. Peak Peak Calculated Minimum Numeric Freq. Band Antenna Output Output Safe Distance Separation Gain (MHz) Gain (dBi) Power Power @ 1mW/cm2 Distance (numeric) (dBm) (mW) Limit(cm) (cm) 2400 – 2483.5 7.5 5.62 21.63 146 8.1 20 5725 - 5850 7.5 5.62 24.09 257 10.8 20 5150 - 5250 7.5 5.62 16.38 43.5 4.5 20 5250 - 5350 7.5 5.62 22.35 172 8.8 20 5470 -5725 7.5 5.62 21.67 147 8.1 20 Assessment for simultaneous operation in 2.4 GHz and 5 GHz bands The Aruba APIN0204, APIN0205 has two radio modules and can transmit simultaneously in the 2.4 GHz and 5 GHz bands. The following assessment is based on simultaneous operation in the 2.4 GHz and 5 GHz bands. Peak Peak Calculated Minimum Numeric Freq.

Note: for mobile or fixed location transmitters the minimum separation distance is 20cm, even if calculations indicate the MPE distance to be less.
