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:


                                                           ��
                                                      =
                                                          �� �
    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




  5.2. Collocated Power Density Calculation
                                                                                            % (Power Density / Limit)

  Note:
  1.   The WWAN wireless module (FCC ID: NZNMCT7355) is also integrated into this host, and collocated power density
       calculation in above table.
  2.X (Power Density / Limit): This is a summation of [{power density for each transmitter/antenna included in the
       simultaneous transmission)/ (corresponding MPE limit)], for WWAN + WLAN.
  3.    Considering the WWAN module collocation with the WLAN transmitter of the EIRP performance listed in the table
       above, the aggregated (power density /limit) is smaller than 1, and MPE of 2 collocated transmitters is compliant




  Conclusion:

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