                                MPE Calculations for WIFI

1. Antenna Gain:
                 2412MHz~2462MHz:2.3 dBi (PIFA Antenna)
                 5150MHz~5850MHz:4.1 dBi (PIFA Antenna)
2. EUT Operation Condition:
   Software provided by client enabled the EUT to transmit and receive data at lowest, middle
   and highest channel individually.

3. Exposure Evaluation:
   Equation from page 18 of OET Bulletin 65, Edition 97-01
     S=(PG)/4πR2
   Where
      S: power density
      P: power input to the antenna
      G: power gain of the antenna in the direction of interest relative to an isotropic radiator.
      R: distance to the center of radiation of the antenna

Note:
(1) NTX= Number of Transmit Antennas
(2) RF Output power specifies that Maximum Conducted Peak Output Power for 2.4G and Maximum
    Conducted Average Output Power for 5G.
(3) Maximum Output Power including Turn-up Tolerance was used to calculate MPE.

5. Conclusion:
As specified in Table 1B of 47 CFR 1.1310- Limits for Maximum Permissible Exposure (MPE),
                 Limits for General Population/ Uncontrolled Exposure
                        Frequency Range                  Power density
                              (MHz)                        (mW/ cm2)
                            300-1,500                       F/1500
                          1,500-100,000                       1.0

  For 2.4G: 802.11b/g/n (2412~2462 MHz)
        5G: U-NII-1: 5150MHz~5250MHz
            U-NII-3: 5725MHz~5850MHz
  MPE limit S: 1 mW/ cm2
  The MPE is calculated as 0.01650632mW / cm2 < limit 1 mW / cm2. So, RF exposure limit
  warning or SAR test are not required.

  The EUT will only be used with a separation of 20cm or greater between the antenna and
  nearby persons and can therefore be considered a mobile transmitter per 47 CFR2.1091
  (b).
