ARUB148                        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.

Assessment for simultaneous operation in 2.4 GHz and 5 GHz bands

The Aruba APIN0114, APIN0115 has two identical radio modules. Each module is dual
band, but each one is dedicated to operate ONLY in 1 band (2.4 GHz or 5 GHz). The
following assessment is based on simultaneous operation in the 2.4 GHz and 5 GHz
bands.

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