Regulatory Compliance
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.
As long as 2 conditions above are met, further transmitter test 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 can not 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
This transmitter module is authorized only for use in device where the antenna may be installed such that 20 cm may
be maintained between the antenna and users (for example access points, routers, wireless ADSL modems, and
similar equipment). The final end product must be labeled in a visible area with the following: “Contains TX FCC ID:
PKW-WM11”.
Manual Information That Must be Included
The users manual for end users must include the following information in a prominent location “ IMPORTANT NOTE:
To comply with FCC RF exposure compliance requirements, the antenna used for this transmitter must be installed
to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in
conjunction with any other antenna or transmitter.
FCC 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 or more of the following measures:
y Reorient or relocate the receiving antenna.
y Increase the separation between the equipment and receiver.
y Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
y Consult the dealer or an experienced radio/TV technician for help.
You are cautioned that changes or modifications not expressly approved by the party responsible for compliance could void your authority to operate the equipment.
IMPORTANT NOTE:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. In order to
avoid the possibility of exceeding the FCC radio frequency exposure limits, human proximity to the antenna shall not
be less than 20cm (8 inches) during normal operation.
This transmitter must not be co-located or operation in conjunction with any other antenna or transmitter

What 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.
Using WLANs, users can conveniently access shared information, and network administrators can configure
and augment networks without installing or moving network cables.
WLAN technology provides users with many convenient and cost saving features:
• Mobility: WLANs provide LAN users with access to real-time information anywhere in their organiza-
tion, providing service opportunities that are impossible with wired networks.
• Ease of Installation: Installing is easy for novice and expert users alike, eliminating the need to install
network cables in walls and ceilings.
• Scalability: WLANs can be configured in a variety of topologies to adapt to specific applications and
installations. Configurations are easily changed and range from peer-to-peer networks suitable for a
small number of users to full infrastructure networks of thousands of users roaming over a broad area.
