FCC ID : 2AJOF-ATOM500SDI-RX 1. RF EXPOSURE 1.1. The Requirement System 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 levels in excess of the Commission’s guidelines. See Section 15.407 1.2. Limit For Maximum Permissible Exposure (MPE) Limits for General Population/ Uncontrolled Exposure F = frequency in MHz, * Plane-wave equivalent power density 1.3. MPE Calculation Method Predication of MPE limit at a given distance Equation from page 18 of OET Bulletin 65, Edition 97-01 S=PG/4πR² Where: S=power density P=power input to antenna 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 From the peak EUT RF output power, the minimum mobile separation distance, d=0.2m, as well as the gain of the antenna is 2.5dBi, the RF power density can be obtained. Frequency Range (MHz) Electric Field Strength (E) (V/m) Magnetic Field Strength (H) (A/m) Power Density (S) ( 2 mW/cm) Averaging Time 2 E, 2 H 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 1.4.
