1. Introduction

WF-M668-UWP1 is based on MT7668AUN,complied with IEEE 802.11ab/g/n/ac dual-band WIFI
subsystem and a Bluetooth subsystem..

1.1 RF module Overview

The general HW architecture for the module is shown in Figure 1. This WLAN Module design is based
on MTK MT7668AUN. It is a highly integrated single-chip MIMO(Multiple In Multiple Out) Wireless LAN
(WLAN) USB2.0 network interface controllercomplying with the 802.11n specification. It combines a
MAC, a 2T2R capable baseband,and RF in a single chip. The MT7668 provides a complete solution for
a highthroughput performance wireless client.The Bluetooth subsystem contains the Bluetooth
radio,baseband,link controller.It also uses the 32-bit RISC MCU for the Bluetooth protocols.

B、FCC Radiation Exposure Statement

Changes or modifications not expressly approved by the party responsible for compliance could void the user's
authority to operate the equipment.
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of
the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and
used in accordance with the
instructions, may cause harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:

-- Reorient or relocate the receiving antenna.

-- Increase the separation between the equipment and receiver.

-- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

-- Consult the dealer or an experienced radio/TV technician for help
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.
FCC Radiation Exposure Statement
The modular can be installed or integrated in mobile or fix devices only. This modular 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 collocated or operating in conjunction with
antenna or transmitter. 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 label referring to the
enclosed module. This exterior label can use wording such as the following:” Contains Transmitter Module FCC ID:
2AOKI-WFM668UWP1 Or Contains FCC ID: 2AOKI-WFM668UWP1 when the module is installed inside another
device, the user manual of this device must contain below warning statements;1. 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.(2) This device must accept any interference received, including interference that may undesired
operation.2. Changes or modifications not expressly approved by the party responsible for compliance could void the
user's authority to operate the equipment. The devices must be installed and used in strict accordance with the
manufacturer’s instructions as described in the user documentation that comes with the product. This device is
intended only for OEM integrators under the followingconditions:1) The antenna must be installed such that 20 cm is
maintained between the antenna and user.2) The transmitter module may not be co-located with any other transmitter
or antenna. Module Antenna Type: BT: Ceramic Antenna, Wifi: Integral Antenna, ANT Gain: BT: 1dBi, 2.4G Wifi: 1dBi,
