3.0 MPE MEASUREMENT GUIDELINES

The Federal Communications Commission (FCC) has adopted the guidelines for evaluating the
environmental effects of radio frequency radiation in ET Docket 93-62 on August 6, 1996 to
protect the public from the potential hazards of RF emissions (1). The safety limits used for the
environmental evaluation measurements are based on the criteria published by the American
National Standards Institute (ANSI) for localized MPE in IEEE/ANSI C95.1-1992 Standard for
Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3
kHz – 300 GHz (2). The measurement procedure described in IEEE/ANSI C95.3-1992
Recommended Practice for the Measurement of Potentially Hazardous Electromagnetic Fields –
RF and Microwave (3) is used for guidance in measuring MPE due to RF exposure from the
particular transmitting device. The new guidelines incorporate limits for MPE in terms of
electric and magnetic field strength, and power density for transmitters operating at frequencies
between 300 kHz and 100 GHz. This criteria for MPE evaluation is also described in OET
Bulletin 65 (Edition 97-01), Evaluation Compliance with FCC Guidelines for Human Exposure
to Radio Frequency Electromagnetic Fields (4).

4.0 DEFINITION

MPE is the rms and peak electric and magnetic field strength, their squares, or the plane-wave
equivalent power densities associated with these fields to which a person may be exposed
without harmful effect, and with an acceptable safety factor.

The MPE prescribed by the standard are set in terms of different parameters of effects,
depending on the frequency generated by the device. The MPE levels are set in terms of power
density, whose definition and relationship to electric and magnetic field strengths are described
by the following equation:


                   S(mW / cm2) =       E2 = 37.7H2
                                      3770

where:

         S = Power density (mW/cm2)
         Power per unit area normal to the direction of propagation usually expressed in units of
         watts per square meter (W/m2), or units of milliwatts per square centimeter (mW/cm2).
         For plane waves, power density, electric field strength (E), and magnetic field strength
         (H) are related by the impedence of free space (377 Ω).

         E = Electric field strength (V/m)

         H = Magnetic field strength (A/m)

6.0 DETAILS OF MPE EVALUATION

The Itronix T5200 Rugged Laptop PC with RIM 801D ARDIS Radio Modem (FCC ID:
KBCT5200RIM801D) and vehicle cradle loaded with a unity gain vehicle rooftop magnetic
mount antenna was found to be compliant for MPE based on the following test provisions and
conditions:

1) The probe was positioned above a simulated metal vehicle rooftop at a separation distance of
   20.0cm from the radiating antenna and at a starting height of 5.0cm to the center of the probe.
2) The turntable was positioned so that the initial start angle was 0 degrees.
3) The EUT was turned on to allow for sufficient time for stabilization. The EUT was operated
   at full power on a desired frequency.
4) The Survey Meter was set for maximum hold and on the appropriate power range.
5) The turntable was rotated about 360 degrees and the maximum reading was obtained for that
   elevation.
6) The EUT was then turned off and the probe raised by 5.0cm. This process was repeated to a
   sufficient distance past the tip of the antenna or where the maximum radiation was reduced
   by a significant factor to warrant no further measurement. The data was then tabulated and
   graphed in the charts and tables shown on next pages.




                                                                4cm spacing

8.0 SYSTEM CALIBRATION

Prior to the assessment for MPE, the Electromagnetic Radiation Survey Meter and probe was
calibrated as per the operating instructions in the operations manual. The unit was placed into
the units electrically sealed storage case and allowed sufficient time for both units to acquire the
same temperature. The system was then calibrated by a built in software routine and zeroed in
an electromagnetic free environment
