1         MPE EVALUATION OF MOBILE DEVICES
Human exposure to RF emissions from mobile devices (47 CFR §2.1091) may be evaluated based on the
MPE limits adopted by the FCC for electric and magnetic field strength and/or power density, as appropriate,
since exposures are assumed to occur at distances of 20 cm or more from persons.



1.1       LIMITS FOR GENERAL POPULATION/UNCONTROLLED EXPOSURE
                                                                  2

Note:
1. For 2412~2462 MHz band
    Directional gain = 3.6+10* log(2/1) = 6.61 dBi
    For 5150~5250 MHz band
    Directional gain = 4.75+10* log(3/1) = 9.52 dBi
    For 5745~5850 MHz band
    Directional gain = 4.75+10* log(3/1) = 9.52 dBi


MPE Evaluation of Simultaneous Transmission
2.4 and 5GHz can transmit at the same time, MPE evaluation is as below formula

PD1 / Limit1 + PD2 / Limit 2 + ….. < 1, PD = Power density

Non-beamforming mode
MPE Evaluation = Maximum MPE of 2.4GHz + Maximum MPE of 5 GHz = 0.072 / 1 + 0.084 / 1 = 0.156 < 1

Beamforming mode
MPE Evaluation = Maximum MPE of 2.4GHz + Maximum MPE of 5 GHz = 0.072 / 1 + 0.141 / 1 = 0.213 < 1

Conclusion
MPE evaluations of single and simultaneous transmission meet the requirement of standard.
