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.
