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

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

Windows® operating system. USI provides

extensive technical documentation on
integration issues such as antenna design,
customizing drivers, and management
software.

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 Information

FCC (United States)

The computer equipment described in this manual generates and uses radio frequency (RF) energy.
If the equipment is not installed and operated in strict accordance with the manufacturer's
instructions, interference to radio and television reception might result.

This equipment complies with Part 15 of the FCC Rules. Operation is subject to the following
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.

Part 15, Class B, of the FCC Rules, is designed to provide reasonable protection against radio and
television interference in a residential installation. Although the equipment has been tested and
found to comply with the allowed RF emission limits, as specified in the above cited Rules, there is
no guarantee that interference will not occur in a particular installation. Interference can be
determined by turning the equipment off and on while monitoring radio or television reception. The
user may be able to eliminate any interference by implementing one or more of the following
measures:

Reorient the affected device and/or its receiving antenna.
Increase the distance between the affected device and the computer equipment.
Plug the computer and its peripherals into a different branch circuit from that used by the
affected device.
If necessary, consult an experienced radio/television technician for additional suggestions.

NOTE: Changes or modifications to the electronics or enclosure of this product must be expressly

approved by Iomega; otherwise, the user's authority to operate this product might be voided by the
FCC.
