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.

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.

Information

To assure continued compliance, (example - use only shielded interface cables when
connecting to computer or peripheral devices) 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 20cm between the radiator & your body.

This transmitter must not be co-located or operating in conjunction with any other

antenna or transmitter.

3

For OEM integrators

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 the 2 conditions above are met, further transmitter testing 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 devices where the antenna may
be installed such that 20 cm may be maintained between the antenna and users (for
example Notebook PC, access points, routers, wireless ASDL modems, and similar
equipment). The final end product must be labeled in a visible area with the
following: "Contains TX FCC ID: NKRDRCM".

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."

Additional Information That Must be Provided to OEM Integrators

The end user should NOT be provided any instructions on how to remove or install
the device.

The module is for OEM installation only and can not be sold to end user directly.

Important Note:

This module is restricted to mobile configuration. The antennas of module should be
installed and operated with minimum distance 20cm between the radiator and all
persons. This transmitter must not be co-located or operating in conjunction with any
other antenna or transmitter.

The end user should NOT be provided any instructions on how to remove or install
the device.

The module is for OEM installation only and can not be sold to end user directly.

(3). This module must be labeled with FCC ID. (See label 3)

(4). If the FCC ID is not visible when the module is installed inside another
device, then the outside of device must also display a label referring to the
enclosed module. The exterior label can be
“ Contains Transmitter Module FCC ID:NKRDRCM ” or similar wording. (See
label 4)

Label 3

Contains Transmitter Module DRCM-81
FCC ID: NKRDRCM

Please put Label 3 & Label 4 to the enclosure of end product to note the end user.

1. Introduction

1.1 The WLAN 802.11g

802.11g is a 54Mbps wireless networking standard that's almost five times faster than

the widely deployed 802.11b products found in homes, businesses, and public
wireless hotspots. Because both 802.11b and 802.11g share the same 2.4GHz radio
band, 802.11g devices can also work with existing 11Mbps 802.11b equipment.

Once connected to a wireless network, you can keep in touch with your e-mail, access
the Internet, and share files and other resources such as printers and network storage
with other computers on the network, wherever you wander. At home, you can surf
the web or use instant messaging to chat with friends while sitting out on the patio.
You'll also be able to connect with any of the growing number of public wireless
hotspots springing up in coffee shops, airport lounges, hotels and convention centers.
And as those hotspots upgrade to the new high-speed 802.11g standard, you'll be
ready to take advantage of the increased speeds. Get connected to current-standard

802.11b networks today, and be prepared for the future with the 802.11g miniPCI.
