MPE Analysis Report
The Equipment Under Test (EUT) Model: Z-206USWKL is a USB wifi socket, which equipped
with a WLAN module. After connecting the EUT to the WLAN network, user can control the home
appliance via smartphone Apps. The EUT has two USB ports for charging external devices
purpose only.
The Equipment Under Test (EUT) operates at frequency range of 2412MHz to 2462MHz with 11
channels.

Antenna gain is 2dBi
For Maximum Permissible Exposure (MPE) evaluation of the USB wifi socket, the maximum
power density at 20 cm from this mobile transmitter shall be less than the General Population /
Uncontrolled MPE limit in OET Bulletin 65.
For WiFi portion, maximum conducted power is 22 dBm (158.5 mW). The antenna gain is 2 dBi
= 1.58 (num gain) and the maximum source-based time-averaging duty factor is 100%. From
these data, the exposed power density at a distance (R) of 20cm from the center of radiation of
the antenna can be calculated according to OET Bulletin 65 as follow:
The radiated (EIRP) source-based time-averaging output power
= conducted power (dBm) + antenna gain (dBi)
= 22 dBm + 2dBi
= 24dBm
(= 251.2 mW)
The power density at 20 cm from the antenna
= EIRP / 4πR^2
= 0.05 mW cm-2
In the frequency range of 1,500 - 100,000MHz, the MPE limit is 1.0 mWcm-2 for
general population and uncontrolled exposure. As the measured power density at
20cm from the transmitter is lower than the MPE limit, the compliance to the MPE
limit can be ensured by indicating the minimum 20cm separation between the
transmitter's radiating structures and body of the user or nearby persons.
The following RF exposure statement is proposed to be included in the user manual:
“ FCC RF Radiation Exposure Statement
Caution: To maintain compliance with the FCC’s RF exposure guidelines, place
the product at least 20cm from nearby persons.”
