CERPASS TECHNOLOGY CORP. Report No.: TEFI1812207 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 3770  d / 100 2 d Where d = Distance in cm P = Power in mW G = Numeric antenna gain S = Power density in mW / cm2 Cerpass Technology Corp.
