Federal Communication Commission Interference Statement
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 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.
FCC Caution: Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate this equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:

The OEM integrator has to be aware not to provide information to the end user
regarding how to install or remove this RF module in the user’s manual of the end
product which integrates this module.
The end user manual shall include all required regulatory information/warning as show in this manual.
This transmitter module is authorized only for use in device where the antenna may be installed such
that 20cm may be maintained between the antenna and users. The final end product must be labled
in a visiable area with the following: "Contains TX FCC ID:N89-WM820B" .

Preface
Operation is subject to the following two conditions: (1) this device may not cause interference and (2)
this device must accept any interference, including interference that may cause undesired operation
of the device.
For product available in the USA/Canada market, only channel 1~11 can be operated. Selection of
other channels is not possible.
This device and its antenna(s) must not be co-located or operation in conjunction with any other
antenna or transmitter.
To reduce potential radio interference to other users, the antenna type and its gain should be so
chosen that the equivalent isotropically radiated power (e.i.r.p) is not more than that permitted for
successful communication.
Caution:
The device for the band 5725-5850 MHz is only for indoor usage to reduce potential for harmful
interference to co-channel mobile satellite systems.
IMPORTANT NOTE:
IC Radiation Exposure Statement:
This equipment complies with IC radiation exposure limits set forth for an uncontrolled environment.
This equipment should be installed and operated with minimum distance 20cm between the radiator
and your body.
The device could automatically discontinue transmission in case of absence of information to transmit,
or operational failure. Note that this is not intended to prohibit transmission of control or signaling
information or the use of repetitive codes where required by the technology.
The device for the band 5725-5850 MHz is only for indoor usage to reduce potential for harmful
interference to co-channel mobile satellite systems.
The maximum antenna gain permitted (for devices in the band 5725-5825 MHz) to comply with the
e.i.r.p. limits specified for point-to-point and non point-to-point operation as appropriate, as stated in
section A9.2(3).
Any changes or modifications not expressly approved by the manufacturer could void the user's
authority to operate this equipment.
USERS MANUAL OF THE END PRODUCT:
In the users manual of the end product, the end user has to be informed to keep at least 20cm
separation with the antenna while this end product is installed and operated. The end user has to be
informed that the IC radio-frequency exposure guidelines for an uncontrolled environment can be
satisfied. The end user has to also be informed that any changes or modifications not expressly
approved by the manufacturer could void the user's authority to operate this equipment. IC statement
is required to be available in the users manual: This Class B digital apparatus complies with
Canadian ICES-003. Operation is subject to the following two conditions: (1) this device may not

WM821-M MiniPCI Module
Chapter 1
Introduction
The WM820-B is quad-mode wireless network adapter that works on all the frequencies allocated for
WLAN operation everywhere in the world. It is in compliance with the Draft IEEE802.11n standard in a
2x3 MIMO configuration. It also complies with the IEEE 802.11a, standards. WM820-B features the
compactness and high bus speed of the Mini PCI specifications which gives users of laptops, notebooks,
tablet PCs, and other mobile computing devices transparent Internet access anywhere in the world
through any Wi Fi network without software changes or additional hardware.
Able to provide greater than 100Mbps real world throughput using high-speed spatial multiplexing
modes, the WM821-M provides the freedom to work as you wish, wherever you wish, using whatever
kind of application you wish to use. The adapter installs directly in any host device with a Mini PCI slot:
just plug it in and you’re ready to access local resources and/or the Internet at the highest speed the
WLAN, the location, and the host computer can provide. It is ready to work “out of the box” in any
embedded device or in any computer running Microsoft® Windows 2000, or XP. The WM820-B Mini
PCI Card is truly a “must-have” for every productivity-sensitive laptop, notebook, or tablet PC user and
any bandwidth-sensitive embedded design..

WiFi-Protected Setup(WPS)-supportedWhat is Wireless LAN?
Wireless Local Area Network (WLAN) systems offer a great number of advantages over traditional wired
systems. WLANs are flexible and easy to setup and manage. They are also more economical than
wired LAN systems.
Using radio frequency (RF) technology, WLANs transmit and receive data through the air. WLANs
combine data connectivity with user mobility. For example, users can roam from a conference room to
their office without being disconnected from the LAN.
