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. This transmitter must not be co-located or operating in
conjunction with any other antenna or transmitter. 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
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 Caution: Any changes or modifications not expressly approved by the
party responsible for compliance could void the user's authority to operate
this equipment.
IMPORTANT NOTE:
FCC RADIATION EXPOSURE STATEMENT
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and
operated with minimum distance 20 cm between the radiator and your
body.
This transmitter must not be co-located or operating in conjunction with
any other antenna or transmitter.
IEEE 802.11b or 802.11g operation of this product in the U.S.A. is
firmware-limited to channels 1 through 11.

OMPLIANCES
THIS DEVICE IS INTENDED ONLY FOR OEM INTEGRATORS UNDER THE
FOLLOWING CONDITIONS:
1. The antenna must be installed such that 20 cm is maintained between
the antenna and users, and
2. The transmitter module may not be co-located with any other
transmitter or antenna.
3. For all products marketed in the US, OEM has to limit the operation
channels in CH1 to CH11 for 2.4 GHz band by supplied firmware
programming tool. OEM shall not supply any tool or info to the end-user
regarding to Regulatory Domain change.
As long as the three conditions above are met, further transmitter tests will
not be required. However, the OEM integrator is still responsible for testing
their end-product for any additional compliance requirements required with
this module installed (for example, digital device emissions, PC peripheral
requirements, etc.).
IMPORTANT NOTE: In the event that these conditions cannot be met (for
example certain laptop configurations or co-location with another
transmitter), then the FCC authorization is no longer considered valid and
the FCC ID can not be used on the final product. In these circumstances,
the OEM integrator will be responsible for re-evaluating the end product
(including the transmitter) and obtaining a separate FCC authorization.
END PRODUCT LABELING

1 INTRODUCTION
PCI Express Card Connector
The WMG623A is a Wi-Fi PCI Express Card that allows simple design-in
802.11b/g/n Wi-Fi functionality for various products, such as notebooks
and home gateways.
The WMG623A includes a built-in high-performance CPU that off-loads WiFi packet processing tasks from the main processor. The hardware form
factor follows the PCI Express standard, but the data path conforms to an
RGMII interface. The result is a card that delivers a higher data transmit
rate than conventional mini-PCI modules.
The WMG623A is compliant with IEEE 802.11n standard and operates in
the 2.4 GHz frequency band. The card’s MIMO antenna architecture is 2T3R
(two transmit, three receive), which supports up to 450 Mbps throughput
rate. The card also supports 20 MHz and 40 MHz bandwidth channels, as
specified in the 802.11n standard.

ACCESS POINT An internetworking device that seamlessly connects wired and wireless
networks. Access points attached to a wired network, support the creation
of multiple radio cells that enable roaming throughout a facility.
AES Advanced Encryption Standard: An encryption algorithm that implements
symmetric key cryptography. AES provides very strong encryption using a
completely different ciphering algorithm to TKIP and WEP.
AUTHENTICATION The process to verify the identity of a client requesting network access.
IEEE 802.11 specifies two forms of authentication: open system and
shared key.
BACKBONE The core infrastructure of a network. The portion of the network that
transports information from one central location to another central location
where it is unloaded onto a local system.
BEACON A signal periodically transmitted from the access point that is used to
identify the service set, and to maintain contact with wireless clients.
BROADCAST KEY Broadcast keys are sent to stations using dynamic keying. Dynamic
broadcast key rotation is often used to allow the access point to generate a
random group key and periodically update all key-management capable
wireless clients.

and to national time standards via wire or radio.
OPEN SYSTEM A security option which broadcasts a beacon signal including the access
point’s configured SSID. Wireless clients can read the SSID from the
beacon, and automatically reset their SSID to allow immediate connection
to the nearest access point.

cell; i.e., Basic Service Set (BSS).
SESSION KEY Session keys are unique to each client, and are used to authenticate a
client connection, and correlate traffic passing between a specific client and
the access point.
SHARED KEY A shared key can be used to authenticate each client attached to a wireless
