4. RF Exposure Limit Introduction
According to ANSI/IEEE C95.1-1992, the criteria listed in Table 1 shall be used to evaluate the environmental impact of

human exposure to radio frequency (RF) radiation as specified in §1.1310.




    The MPE was calculated at 20 cm to show compliance with the power density limit.
    The following formula was used to calculate the Power Density:


                                                           𝐏𝐆
                                                    𝐒=
                                                          𝟒𝛑𝐑𝟐
    Where:
    S = Power Density
    P = Output Power at Antenna Terminals
    G = Gain of Transmit Antenna (linear gain)
    R = Distance from Transmitting Antenna

Note: For conservativeness, the lowest frequency of each band is used to determine the MPE limit of that band




Conclusion:

According to 47 CFR §2.1091, the RF exposure analysis concludes that the RF Exposure is FCC compliant.
