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) Maximum Antenna Gain Tune-up Conducted Power Evaluation Distance (cm) Power Density (mW/cm 2 ) MPE Limit (mW/cm 2 ) (dBi) (numeric)(dBm) (mW) 802.11a 5150~5250 1.50 1.41 22.0 158.49 20 0.0445 1.0 5725~5850 1.50 1.41 16.5 44.67 20 0.0126 1.0 802.11n- HT20 5150~5250 1.50 1.41 21.5 141.25 20 0.0397 1.0 5725~5850 1.50 1.41 16.0 39.81 20 0.0112 1.0 Note: (1) The Tune-up output power was declared by the Manufacturer. Conclusion: The device meets MPE at distance 20cm.
