R.F Exposure/Safety Calculation for
RAU-5X
The E.U.T. is rack or wall mounted. The typical distance between the E.U.T. and the
general population is >50cm.

Calculation of Maximum Permissible Exposure (MPE)
Based on Section 1.1310 Requirements

(a) (LTE) FCC limit at 747 MHz is: mW
f / 1500 = 0.498
cm 2

mW
(b) (CELL) FCC limit at 874.2 MHz is: f / 1500 = 0.583
cm 2

mW
(c) (ESMR) FCC limit at 867.8 MHz is: f / 1500 = 0.579
cm 2

(d) (PCS) FCC limit at 1993.8 MHz is: mW
1
cm 2

mW
( e) (AWS) FCC limit at 2178.8 MHz is: 1
cm 2

Using table 1 of Section 1.1310 limit for general population/uncontrolled
exposures, the above level is an average over 30 minutes.
(b)The power density produced by the E.U.T. is

Pt Gt
S=
4πR 2

Pt- Transmitted Peak Power (worst case)
GT- Antenna Gain, 12.5dBi= 17.8 numeric
R- Distance from Transmitter 50 cm

(c ) Peak power density at worst case continuous transmission:

Band Modulation Pt Antenna GT GT R SAV Spec
(mW) type (dBi) numeric (cm) (mW/cm ) (mW/cm2)
