1. MAXIMUM PERMISSABLE EXPOSURE
Calculations for Maximum Permissible Exposure Levels
                             2           2
Power Density = Pd (mW/cm ) = EIRP/(4*π*d )
EIRP = P * G
P = Peak output power (mW)
G = Antenna numeric gain (numeric)
d = Separation distance (cm)
Numeric Gain = 10 ^ (G (dBi)/10)

The calculations in the table below use the highest conducted power values together with the lowest
antenna gain specified for the EUT. These calculations represent worst case in terms of the exposure
levels.

Assessment for simultaneous operation in LTE and WCDMA bands

The Rockwell Collins has two radio modules and can transmit simultaneously in the LTE and WCDMA
bands. The following assessment is based on simultaneous operation in the LTE and WCDMA bands.
