RF Exposure Evaluation Test Standard FCC CFR47, Part 1, 1307 (b), 1310 FCC CFR47, Part 2, Subpart J 1091 FCC 1.1310 states the criteria listed in the table below shall be used to evaluate the environmental impact of human exposure to radiofrequency (RF) radiation as specified in Section 1.1307(b), except in the case of portable devices which shall be evaluated according to the provisions of Section 2.1093 of this chapter. Further information on evaluating compliance with these limits can be found in the FCC's OST/OET Bulletin Number 65, “Evaluating Compliance with FCC-Specified Guidelines for Human Exposure to Radiofrequency Radiation”. Frequency Electric Field Magnetic Field Power Density Average Range (MHZ) Strength (V/m) Strength (A/M) (mW/cm2) Time, min (A) Limits for Occupational/Control Exposures 300-1500 -- -- F/300 6 1500-100,000 -- -- 5 6 (B) Limits for General Population/Uncontrolled Exposures 300-1500 -- -- F/1500 6 1500-100,000 -- -- 1 30 EUT Operating Condition RF exposure evaluation distance calculation Case 1: Signal with BW < 1 MHz 2.1 GHz radio with 18.7 dBi antenna Output Power to Antenna r Freq (MHz) Antenna (dBm) Gain (dBi) (cm) 2122 43.5 18.7 328.9 2132 43.5 18.7 330.2 2142 43.5 18.7 331.4 As shown above, the minimum distance where the MPE limit is reached is 331.4 cm for the EUT. Case 2: Signal with spectral density < 41.2 dBm/MHz 2.1 GHz radio with 21.0 dBi antenna Output Power to Antenna r Freq (MHz) Antenna (dBm) Gain (dBi) (cm) 2122 43.5 21.0 427.4 2132 43.5 21.0 430.3 2142 43.5 21.0 434.0 As shown above, the minimum distance where the MPE limit is reached is 434.0 cm for the EUT.
