TEST RESULTS


No non-compliance noted.

Calculation
               30  P  G       E2
Given    E               & S
                   d           3770
         Where    E = Field strength in Volts / meter
                  P = Power in Watts
                  G = Numeric antenna gain
                  d = Distance in meters
                  S = Power density in milliwatts / square centimeter
Combining equations and re-arranging the terms to express the distance as a function of the remaining
variables yields:
              30  P  G
         S
               3770d 2

Changing to units of mW and cm, using:

         P (mW) = P (W) / 1000 and
         d (cm) = d(m) /100
Yields
              30  P / 1000  G           PG
         S                        0.0796  2        Equation 1

                                             d

         Where    d = Distance in cm
                  P = Power in mW
                  G = Numeric antenna gain
                  S = Power density in mW / cm2
