$Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: RSC190723005-00 §1.1307 (b) (1) & §2.1091- MAXIMUM PERMISSIBLE EXPOSURE (MPE) Applicable Standard According to FCC §15.319(i) and §1.1307(b)(1), 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) Frequency Electric Field Magnetic Field Power Density Averaging Time Range (MHz) Strength (V/m) Strength (A/m) (mW/cm2) (minute) Limits for General Population/Uncontrolled Exposure 0.3-1.34 614 1.63 *(100) 30 1.34-30 842/f 2.19/f *(180/f\2\) 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 MPE Calculation Predication of MPE limit at a given distance PG S= 4R 2 Where: S = 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 R = distance to the center of radiation of the antenna (appropriate units, e.g., cm); For worst case: Tune-up conducted Evaluation Power Frequency Antenna Gain MPE Limit power Distance Density (MHz) (mW/cm2) (dBi) (numeric) (dBm) (mW) (cm) (mW/cm2) 1921.536 - 2.53 1.79 19.0 79.43 20 0.028 1.0 1928.448 Result: Compliance. To maintain compliance with the FCC’s RF exposure guidelines, place the equipment at least 20cm from nearby persons. FCC Part 15D Page 10 of 43$
