Limits for Maximum Permissible Exposure (MPE) (§1.1310, §2.1091) (B) Limits for General Population/Uncontrolled Exposure Frequency Range (MHz) Electric Field Strength (V/m) Magnetic Field Strength (A/m) Power Density (mW/cm 2 ) Averaging Time (minutes) 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 30 300-1500 / / f/1500 30 1500-100,000 / / 1.0 30 f = frequency in MHz; * = Plane-wave equivalent power density; According to §1.1310 and §2.1091 RF exposure is calculated. Calculated Formulary: Predication of MPE limit at a given distance S = PG/4πR² = power density (in appropriate units, e.g. mW/cm 2 ); 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); Calculated Data: Mode Frequency Range (MHz) Antenna Gain Tune-up Output Power Evaluation Distance (cm) Power Density (mW/cm 2 ) MPE Limit (mW/cm 2 ) (dBi) (numeric)(dBm)(mW) 802.11b 2412~2462 3.0 2.00 18.00 63.10 20 0.0251 1.0 802.11g 3.0 2.00 16.00 39.81 20 0.0158 1.0 802.11 n-HT20 3.0 2.00 15.50 35.48 20 0.0141 1.0 802.11 n-HT40 2422~2452 3.0 2.00 15.00 31.62 20 0.0126 1.0 Note: The tune-up output power was declared by the manufacturer. Conclusion: The device meets MPE at distance 20cm.
