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”.

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.
