RF Exposure Report FCC ID: 2A3O9-APH320 The EUT is a Air Purifier in the 2412 ~ 2462MHz frequency band. According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environment impact of human exposure to radio frequency (RF) radiation as specified in 1.1307(b) (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 Time |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 1500-100,000 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 Time |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 1500-100,000 1.0 30 Note: f = frequency in MHz MPE calculation method Calculation Method of RF Safety Distance: S: power density mW/ cm 2 ; P: power input to the antenna in mW; g: numeric gain of antenna; r: distance to centre of radiation in cm Calculated result Mode Max.
