1. Introduction

Chapter 1 - Introduction

Overview

Thank you for purchasing the ASUS WLAN Card. The ASUS WLAN Card is
a PCI compliant “wireless” network interface card (NIC) for any computer
equipped with a PC Card slot (available mainly in Notebook PCs).

The ASUS WLAN Card is designed to be fully compliant with both the IEEE

802.11g and IEE802.1 1b wireless local area network (Wireless LAN) standards.
As a result of the completion of the standard, the interoperability of Wireless
LAN products among multiple manufacturers will be guaranteed. The ASUS
WLAN Card product provides high-speed, standards-based Wireless LAN
solutions.

The ASUS WLAN Card is designed to be fully compliant with IEEE 802.11g
wireless local area networks (WLAN). 802.11g is an extension to 802.11b,
used in majority of wireless LANs today . 802.1 1g will broaden 802.1 1b's data
rates to 54 Mbps within the 2.4 GHz band using OFDM (orthogonal frequency
division multiplexing) technology . 802.11g allows backward compatibility with

802.11b devices but only at 11 Mbps or lower depending on the range and
presence of obstructions.

Overview

Chapter 1

The ASUS WLAN Card supports data rates up to 11 Mbps, with automatic
fallback to 5.5, 2, and 1 Mbps in 802.11b networks. It operates in the unlicensed

2.4 GHz frequencies called the Instrumentation, Science, and Medical (ISM)
band. Unlicensed means free of charge to users.

The ASUS WLAN Card configuration utility is a user-friendly application that
helps you quickly setup multiple roaming nodes using the ASUS WLAN Card.
You can even export the configuration settings to a file and import them to
other computers for fast multiple installations using ASUS Mobile Manager.
Wireless LANs are complementary extensions to existing wired LANs, of fering
complete mobility while maintaining continuous network connectivity to both
corporate and home Intranets. They add a new level of convenience for LAN
users. PC users stay connected to the network anywhere throughout a building
without being bound by a LAN wires. This is accomplished through the use of
ASUS WLAN Access Points or ASUS WLAN Home Gateways. ASUS WLAN
Home Gateways with built-in Internet gateway capability , allows your family
to share a broadband Modem and one ISP account simultaneously from dif ferent
rooms without wires! ASUS WLAN products can keep you connected
anywhere, any time.
