1. Introduction

1.1 Overview

The ASUS USB SpaceLink Client is designed to be fully compliant with the
IEEE 802.11b wireless local area network (Wireless LAN) standard. The
ASUS USB SpaceLink Client is equipped with a 6 dBi uni-directional an-
tenna which provides a greater coverage area compared with wireless PC
cards. The ASUS USB SpaceLink Client comes with a mounting kit and a
detachable 1.8 meter USB cable which allows convenient placement on
your desk or office partition. A USB extension cable can be purchased
from third-parties for mounting the ASUS USB SpaceLink Client on the
wall or ceiling. The advantages of the ASUS USB SpaceLink Client is the
increased wireless coverage due to the ability to raise the ASUS USB
SpaceLink Client above obstructions.

The ASUS USB SpaceLink Client product provides high-speed, standards-
based Wireless LAN solutions. Supporting data rates up to 11 Mbps, with
automatic fallback to 5.5, 2, and 1 Mbps. 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 USB SpaceLink
Client configuration utility is a user-friendly application that helps you
quickly setup multiple roaming nodes using the ASUS USB SpaceLink
Client. You can even export the configuration settings to a file and import
them to other computers for fast multiple installations.

Wireless LANs are complementary extensions to existing wired LANs,
offering complete mobility while maintaining continuous network connec-
tivity to both corporate and home Intranets. They add a new level of conve-
nience for LAN users. PC users stay connected to the network anywhere
throughout a building without being bound by a LAN wire. This is accom-
plished through the use of a device known as the Access Point (AP). By
making use of AP in the office, you can easily establish mobile network
connections to the enterprise Intranet or Internet. Moreover, you can bring
your ASUS USB SpaceLink Client home to make your home-networking
dream come true! A home-dedicated AP, with built-in Internet gateway
capability, allows your family to share a broadband Modem and one ISP
account simultaneously with no excessive, tedious ties! Connected any-
where, at any time, your family will feel closer by the invisible magic of
the ASUS USB SpaceLink Client!
