Arcadyan Technology WN4402AARC User Manual

Introduction

1. Introduction
WN4402A 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.
WN4402A 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. 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. WN4402A 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.
The additional hard key function provides a truly flexible usage to directly disable and
re-enable the RF power without going into the utility program.
