Evaluation method and Limit According to ANSI/IEEE C95.1-1992, the Criteria Listed in Table 1 shall be used to evaluate the environmental impact of human exposure to radio frequency (RF) radiation as specified in §1.1310. Frequency range Electric field strength Magnetic field strength Power density Averaging time (MHz) (V/m) (A/m) (mW/cm2) (minutes) (A) Limits for Occupational/Controlled Exposure 0.3-3.0 614 1.63 *100 6 3.0-30 1842/f 4.89/f *900/f2 6 30-300 61.4 0.163 1.0 6 300-1,500 f/300 6 1,500-100,000 5 6 (B) Limits for General Population/Uncontrolled Exposure 0.3-1.34 614 1.63 *100 30 1.34-30 824/f 2.19/f *180/f2 30 30-300 27.5 0.073 0.2 30 300-1,500 f/1500 30 1,500-100,000 1.0 30 f = frequency in MHz * = Plane-wave equivalent power density The MPE was calculated at 20 cm to show compliance with the power density limit. The following formula was used to calculate the Power Density: Where: S = Power Density P = Output Power at Antenna Terminals G = Gain of Transmit Antenna ( linear gain ) R = Distance from Transmitting Antenna ________________________________________________________________________ ___ Page 2 of 4
