Bay Area Compliance Laboratories Corp. (Dongguan) Report No.: RXM180614051-00A FCC §15.247 (i) & §1.1310 & §2.1091- MAXIMUM PERMISSIBLE EXPOSURE(MPE) Applicable Standard According to subpart 15.247(i)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. Calculated Formulary: Predication of MPE limit at a given distance 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: Antenna Gain Tune-up Power Evaluation Power Frequency MPE Limit Distance Density (MHz) (dBi) (numeric) (dBm) (mW) (mW/cm2) (cm) (mW/cm2) 2412-2462 2 1.58 20 100.00 20.00 0.0315 1.0 2402-2480 2 1.58 4.5 2.82 20.00 0.0009 1.0 Result: The device meet FCC MPE at 20 cm distance Page 13 of 57
