802.11G WIRELESS LAN MINI PCI ADAPTER

Data Sheet Nov. 2004 Rev 1.6

Introduction

The Mini-PCI Adapter type-III B is a high-speed
54 Mbits/s wireless networking card providing a
multimode 802.11 b/g or 11g mode only
connectivity for enterprise and home wireless
LAN access.

The Mini-PCI Card uses direct sequence
spread spectrum (DSSS), Orthogonal
Frequency Division Multiplexing (OFDM)
technology, and implements DBPSK, DQPSK,
and CCK, OFDM modulation, as defined in the
IEEE® 802.11b, g. This gives a very robust
radio channel, which is made even better by the
excellent receiver sensitivity and delay spread
robustness.

In environments with radio interference, the
Mini-PCI Card, because of its acknowledgment
protocol and its option to be tuned to another
frequency channel, continues to run.

Superior echo path management makes it
suitable for areas with a large delay spread, for
example, warehouses. This reduces the
number of cells required and, therefore,
reduces the total cost of ownership.

A firmware-based architecture is capable of
supporting the latest industry standards in the
security and quality of service (QoS), as the
draft 802.11i and 802.11e standards,
respectively.

The Mini-PCI Card is complemented by drivers
and networking tools for various versions of the

Antenna Specifications

The Mini-PCI adapter is available in two variants: unique coax connectors with diversity
function.

On-Board Diversity Switch

This variant of the Mini-PCI Card has connectors for two external passive antennas: MAIN and
AUX. One of the antennas is used for transmission, and the DSP selects which of the two to
use for reception, based on signal strength.

All rights are reserved by USI. No part of this technical document can be reproduced in any form without permission of USI.

802.11 b/g Wireless LAN Mini-PCI Adapter

The coax connectors for the antennas are mechanically unique, so that no off-the-shelf
connector will fit (FCC requirement).

Switch electronics for selection between the two antennas for reception of the stronger receive
signal is provided onboard.

Security

At the physical layer, transmissions are encrypted using WEP; three levels of encryption are
possible：

• 40-bit key plus 24-bit initialization vector

• 104-bit key plus 24-bit initialization vector

• 128-bit key plus 24-bit initialization vector

AES, TKIP, WPA draft 802.11i are supported.

Attacks have been made on WEP by exploiting various weaknesses. The Mini-PCI Card
implements random setting of the initialization vector and utilizes WEPplus, which prevents
initialization vectors that result in weak keys being used. WEPplus is completely compatible
with WEP.

For those operating systems that support it either natively or with an add-on supplement (i.e,
Windows 98, Windows 98SE, Windows ME, Windows 2000, Windows XP, the 802.1x,
WPA/TKIP SSN security standard are implemented. This offers port-based network access
control, and automatic key distribution.

Regulatory Statements for BCM94318MPG

USA-Federal Communications Commission (FCC)

This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of 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. If not installed and used in accordance with the instructions, it
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 tuning the equipment off and on, the user is encouraged to try and correct the
interference by one or more of the following measures:

-Reorient or relocate the receiving antenna

-Increase the distance between the equipment and the receiver.

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

-Consult the dealer or an experienced radio/TV technician for help.
Any changes or modifications not expressly approved by the party responsible for compliance
could void the user’s authority to operate the equipment.

Caution: Exposure to Radio Frequency Radiation.

To comply with FCC RF exposure compliance requirements, a separation distance of at least 20 cm must
be maintained between the antenna of this device and all persons. This device must not be co-located or
operating in conjunction with any other antenna or transmitter.

Canada – Industry Canada (IC)

This device complies with RSS 210 of Industry Canada.

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 this device.”

L ‘ utilisation de ce dispositif est autorisée seulement aux conditions suivantes : (1) il ne doit pas
produire de brouillage et (2) l’ utilisateur du dispositif doit étre prêt à accepter tout brouillage
radioélectrique reçu, même si ce brouillage est susceptible de compromettre le fonctionnement
du dispositif.

The term "IC" before the equipment certification number only signifies that the Industry Canada
technical specifications were met.

To reduce potential radio interference to other users, the antenna type and its gain should be so
chosen that the equivalent isotropically radiated power (EIRP) is not more than that required for
successful communication.

To prevent radio interference to the licensed service, this device is intended to be operated
indoors and away from windows to provide maximum shielding. Equipment (or its transmit
antenna) that is installed outdoors is subject to licensing.

Pour empecher que cet appareil cause du brouillage au service faisant l'objet d'une licence, il doit
etre utilize a l'interieur et devrait etre place loin des fenetres afin de Fournier un ecram de
blindage maximal. Si le matriel (ou son antenne d'emission) est installe a l'exterieur, il doit faire
l'objet d'une licence.

Caution: Exposure to Radio Frequency Radiation.

The installer of this radio equipment must ensure that the antenna is located or pointed such that
it does not emit RF field in excess of Health Canada limits for the general population; consult
Safety Code 6, obtainable from Health Canada’s website www.hc-sc.gc.ca/rpb.
