                                 MPE Calculations for WIFI

1. Antenna Gain:
                    PCB Antenna: 1dBi.

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

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 802.11b/g/n:2412~2462 MHz
  MPE limit S: 1mW/ cm2
  The MPE is calculated as 0.01580mW / cm2 < limit 1mW / 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).
