Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: RSZ190219002-00D §1.1307 (b) (1) & §2.1091- MAXIMUM PERMISSIBLE EXPOSURE (MPE) Applicable Standard According to subpart 1.1307 (b)(1), 2.1091 systems operating under the provisions of this section shall be operated in a manner that ensures the public is not exposed to RF energy level in excess of the communication guidelines. Limits for General Population/Uncontrolled Exposure Limits for General Population/Uncontrolled Exposure Frequency Electric Field Magnetic Field Power Averaging Range Strength Strength Density Time (MHz) (V/m) (A/m) (mW/cm2) (Minutes) 0.3-1.34 614 1.63 *(100) 30 2 1.34-30 824/f 2.19/f *(180/f ) 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 Result Calculated Formulary: Predication of MPE limit at a given distance PG S= 4R 2 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, the power gain factor, is normally numeric gain. R = distance to the center of radiation of the antenna (appropriate units, e.g., cm) Tune-up Conducted Evaluation Power Frequency Antenna Gain MPE Limit Power Distance Density (MHz) (mW/cm2) (dBi) (numeric) (dBm) (mW) (cm) (mW/cm2) 5150-5250 4.5 2.82 14.5 28.18 20 0.016 1.0 5250-5350 4.5 2.82 14.5 28.18 20 0.016 1.0 5470-5725 4.5 2.82 14.5 28.18 20 0.016 1.0 5725-5850 4.5 2.82 15.0 31.62 20 0.018 1.0 To maintain compliance with the FCC’s RF exposure guidelines, place the equipment at least 20cm from nearby persons. Result: Compliance FCC Part 15.407 Page 17 of 156
