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:

  Note:
  1. For colocation analysis, GPRS1900 (4TX slot) is chosen for summation due to the highest (power density/limit) among all WWAN
     wireless modes.
  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 EIAP 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.
