Bay Area Compliance Laboratories Corp. (Dongguan) Report No.: RXM180827050-00C FCC §15.407 (f) & §1.1310 & §2.1091- MAXIMUM PERMISSIBLE EXPOSURE (MPE) Applicable Standard According to subpart 15.407(f)and subpart §1.1310, systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. Limits for Maximum Permissible Exposure (MPE) (§1.1310, §2.1091) (B) Limits for General Population/Uncontrolled Exposure Frequency Range Electric Field Magnetic Field Power Density Averaging Time (MHz) Strength (V/m) Strength (A/m) (mW/cm2) (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/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); Calculated Data: Max. Target Power Evaluation Power MPE Frequency Antenna Gain including Distance Density Limit Range Tolerance (cm) (W/m2) (W/m2) (dBi) (numeric) (dBm) (mW) 5150-5850 4.5 2.82 18 63.10 20.00 0.035 1.0 Result: Compliance, The device meets MPE requirement for Devices Used by the General Public (Uncontrolled Environment) at distance ≥20 cm.
