Part Name: WIFI Module
Part No.: 8188 series
Date: 2014-6-25
Part 1˖
˖
Introduction
This product is a new generation module, It is based on USB interface,
accord with Wifi wireless network standard embedded module, the built-in
wireless network protocol IEEE802.11 protocol stack, and TCP/IP protocol stack,
save electricity intelligent control procedures , realize the user serial data to the
wireless network conversion between. The entire module needs a power supply
of 3.3 volt, and it has two Antenna(integral antenna and PCB antenna) to use for
a different product. But it isn’t a MIMO equipment. Both of the antenna was used
independent. When the customer need a PCB antenna, and the integral antenna
will be take out, vise versa.
Through the Wifi module, the traditional serial equipment also can easily access
wireless network.

FCC statement
This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept
any interference received, including interference that may cause undesired operation. Changes
or modifications not expressly approved by the party responsible for compliance could void the
user's authority to operate the equipment.
FCC Radiation Exposure Statement
The modular can be installed or integrated in mobile or fix devices only. This modular cannot be
installed in any portable device, for example, USB dongle like transmitters is forbidden.
This modular complies with FCC RF radiation exposure limits set forth for an uncontrolled
environment. This transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter. This modular must be installed and operated with a minimum distance of
20 cm between the radiator and user body.
If the FCC identification number is not visible when the module is installed inside another device,
then the outside of the device into which the module is installed must also display a label
referring to the enclosed module. This exterior label can use wording such as the following:
“Contains Transmitter Module FCC ID: ROWCDT-H18188E-NX Or Contains FCC ID:
ROWCDT-H18188E-NX ”
when the module is installed inside another device, the user manual of this device must contain
below warning statements;
Integral antenna: 2.0dBi
PCB Antenna: 0dBi
