WN4401C 1-ZZ

Chapter 1 Introduction

1. Introduction

WN4401C is an industrial miniPCI Card which enables wireless networking systems to attain

data transmission speeds at least up to 54 megabits-per-second (Mbps), while remaining

backward compatible to the existing installed base of over 15 million Wi-Fi systems

worldwide. It supports operation to both the IEEE 802.11b and IEEE 802.11g standards.

WN4401C will enable a next generation of high-data-rate platforms for operation in the 2.4

GHz band that deliver a five-fold speed increase. It is fully IEEE 802.11g standard

compliant, and uses prioritization algorithms and enhanced protection mechanisms to

significantly increase pure 802.11g as well as mixed-mode network performance. The cost and

performance advantages will make it an ideal solution for high bandwidth enterprise

applications, such as wireless video conferencing and large file transfers, as well as advanced

home networking applications such as multi-channel CD-quality audio and DVD-quality

video streaming. WN4401C incorporates the 802.11g Standard's mandatory modulation

schemes— Complementary Code Keying (CCK), which is used in 802.11b, and Orthogonal

Frequency Division Multiplexing (OFDM), used in 802.11g. Using CCK ensures

backward-compatibility with the installed Wi-Fi 802.11b base, while OFDM provides the

speed required for today's high-bandwidth applications.
