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. Calculation formula: Prediction of power density at the distance of the applicable MPE limit S = PG/4R² = 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 (MHz) Antenna Gain ▲ Conducted output power including Tune-up Tolerance ▲ Evaluation Distance (cm) Power Density (mW/cm 2 ) MPE Limit (mW/cm 2 ) (dBi) (numeric)(dBm)(mW) BLE 2402-2480 0.6 1.15 17.5 56.23 20.00 0.013 1.0 Note: The Antenna Gain and Conducted output power including Tune-up Tolerance provided by manufacturer.
