1. MAXIMUM PERMISSIBLE EXPOSURE (MPE) 1.1 Standard Applicable According to §1.1307(b)(1), system operating under the provisions of this section shall be operating in a manner that the public is not exposed to radio frequency energy level in excess limit for maximum permissible exposure. (a) Limits for Occupational / Controlled Exposure Frequency range (MHz) Electric Field Strength (E) (V/m) Magnetic Field Strength (H) (A/m) Power Density (S) (mW/cm 2 ) Averaging Times | E | 2 , | H | 2 or S (minutes) 0.3-3.0 614 1.63 (100)* 6 3.0-30 1842/f 4.89/f (900/f)* 6 30-300 61.4 0.163 1.0 6 300-1500 / / F/300 6 1500-100000 / / 5 6 (b) Limits for General Population / Uncontrolled Exposure Frequency range (MHz) Electric Field Strength (E) (V/m) Magnetic Field Strength (H) (A/m) Power Density (S) (mW/cm 2 ) Averaging Times | E | 2 , | H | 2 or S (minutes) 0.3-1.34 614 1.63 (100)* 30 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 1500-100000 / / 1 30 Note: f = frequency in MHz: * = Plane-wave equivalents power density 1.2 MPE Calculation Method S = (30*P*G) / (377*R 2 ) S = power density (in appropriate units, e.g., mw/cm 2 ) 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 (in appropriate units, e.g., cm) 1.3 MPE Calculation Result Wifi: Since the maximum eirp power is used as the output power to antenna, so the Gain of the antenna can be assumed as 0dBi. Maximum peak output power: 15.23 (dBm) Maximum peak output power at antenna input terminal: 33.343(mW) Prediction distance: >20(cm) Prediction frequency: 2462 (MHz) Antenna gain (typical): 0 (dBi) Antenna gain (typical): 1 (numeric) The worst case is power density at prediction frequency at 5cm: 0.0066(mw/cm 2 ) MPE limit for general population exposure at prediction frequency: 1 (mw/cm 2 ) 0.0066(mw/cm 2 ) < 1 (mw/cm 2 ) Result: Pass
