Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: RSZ150714017-00C FCC §15.407 (f) & §2.1091 –MAXIMUM PERMISSIBLE EXPOSURE (MPE) Applicable Standard According to FCC §2.1091 and §1.1307(b) (1), systems operating under the provisions of this section shall be operated in a manner that ensure that the public is not exposed to radio frequency energy level in excess of the Commission’s guideline. 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: 5150-5250MHz: Max tune –up Antenna Gain Conducted Evaluation Power Frequency MPE Limit Mode Power Distance Density (MHz) (mW/cm2) (cm) (mW/cm2) (dBi) (numeric) (dBm) (mW) 802.11a 3.0 2.0 15.0 31.623 20 0.0126 1.0 802.11n- 3.0 2.0 19.5 89.125 20 0.0354 1.0 HT20 802.11n- 5150-5250 3.0 2.0 20.0 100.000 20 0.0397 1.0 HT40 802.11ac20 3.0 2.0 18.5 70.795 20 0.0281 1.0 802.11ac40 3.0 2.0 19.0 79.433 20 0.0315 1.0 802.11ac80 3.0 2.0 19.5 89.125 20 0.0354 1.0 FCC Part 15.407 Page 9 of 194
