MPE Calculations for WIFI
1. Antenna Gain:
Dipole Antenna: 5dBi.
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
4. Test Result:

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
(MHz)
300-1,500
Power density

1.0
For 802.11b/g/n (2412~2462 MHz)
MPE limit S: 1mW/ cm2
The MPE is calculated as 0.0397mW / 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).
The RF Exposure Information page from the manual is included here for reference.
