According to §1.1310 and §2.1091 RF exposure is calculated. Limits for Maximum Permissible Exposure (MPE) Frequency Range (MHz) Electric Field Strength (V/m) Magnetic Field Strength (A/m) Power Density (mW/cm 2 ) Averaging Time (minute) Limits for General Population/Uncontrolled Exposure 0.3-1.34 614 1.63 *(100) 30 1.34-30 842/f 2.19/f *(180/f\2\) 30 30-300 27.5 0.073 0.2 30 300-1500 / / f/1500 30 1500-100,000 / / 1.0 30 f = frequency in MHz * = Plane-wave equivalent power density Test Data Predication of MPE limit at a given distance, Equation from OET Bulletin 65, Edition 97-01 Where: S = power density (in appropriate units, e.g. mW/cm2) P = power input to the antenna (in appropriate units, e.g., mW). G = power gain of the antenna in the direction of interest relative to an isotropic radiator, the power gain factor, is normally numeric gain. R = distance to the center of radiation of the antenna (appropriate units, e.g., cm) Antenna Gain Conducted Power Frequency (MHz) (dBi) (numeric) (dBm)(mW) Evaluation Distance (cm) Power Density (mW/cm 2 ) MPE Limit (mW/cm 2 ) 1921.536 0 1.0 20.33 107.89 20 0.0148 1.0 Result: Complies at 20 cm distance.
