What is Wireless LAN?
Wireless Local Area Network (WLAN) systems offer a great number of
advantages over traditional wired systems. WLAN is flexible and easy to setup
and manage. They are also more economical than wired LAN systems.
Using radio frequency (RF) technology, WLAN transmit and receive data through
the air. WLAN combine data connectivity with user mobility. For example, users
can roam from a conference room to their office without being disconnected from
the LAN.
Using WLAN, users can conveniently access-shared information, and network
administrators can configure and augment networks without installing or moving
network cables.
WLAN technology provides users with many convenient and cost saving features:
• Mobility: WLAN provide LAN users with access to real-time information
anywhere in their organization, providing service opportunities that are
impossible with wired networks.
• Ease of Installation: Installing is easy for novice and expert users alike,
eliminating the need to install network cables in walls and ceilings.
•
Scalability: WLAN can be configured in a variety of topologies to adapt to
specific applications and installations. Configurations are easily changed
and range from peer-to-peer networks suitable for a small number of users
to full infrastructure networks of thousands of users roaming over a broad
.
area
Wireless LAN Modes
Wireless LANs can be configured in one of two ways:
Ad-hoc
Networking
Also known as a peer-to-peer network, an ad-hoc
network is one that allows all workstations and
computers in the network to act as servers to all other
users on the network. Users on the network can share
files, print to a shared printer, and access the Internet
with a shared modem. However, with ad-hoc
networking, users can only communicate with other
wireless LAN computers that are in the wireless LAN
workgroup, and are within range.
Infrastructure
Networking
Infrastructure netw orking d iffers fr om ad-hoc netw orking
in that it includes an access point. Unlike the ad-hoc
structure where users on the LAN contend the shared
bandwidth, on an infrastructure network the access
point can manage the bandwidth to maximize
6

bandwidth utilization.
Additionally, the access point enables users on a
wireless LAN to access an existing wired network,
allowing wireless users to take advantage of the wired
networks resources, such as Internet, email, file
transfer, and printer sharing.
Infrastructure networking has the following advantages
over ad-hoc networking:
• Extended rang e : each wireless LAN computer
within the range of the access point can
communicate with other wireless LAN computers
within range of the access point.
• Roaming: the access point enables a wireless LAN
computer to move through a building and still be
connected to the LAN.
• Wired to wireless LAN connectivity: the access
point bridges the gap between wireless LANs and
their wired counterparts.
Notes on Wireless LAN Configuration
When configuring a wireless LAN (WLAN), be sure to note the following points:
• Optimize the performance of the WLAN by ensuring that the distance
between access points is not too far. In most buildings, WLAN cards operate
within a range of 100 ~ 300 feet, depending on the thickness and structure of
the walls.
• Radio waves can pass through walls and glass but not metal. If there is
interference in transmitting through a wall, it may be that the wall has
reinforcing metal in its structure. Install another access point to circumvent
this problem.
• Floors usually have metal girders and metal reinforcing struts that interfere
with WLAN transmission.
This concludes the first chapter. The next chapter deals with the hardware
installation of the Adapter.

Disconnecting the USB Adapter
In Win 98/ME operating systems, you do not have to power down your
notebook/desktop PC to remove the Adapter. The Adapter is hot swappable—you
can remove the Adapter when your notebook/desktop PC is powered on. However,
Microsoft recommends that you stop the Adapter before removing the Adapter. Refer
to your Win 98/ME online help for information on stopping the USB Adapter.
WARNING: Do not remove the USB Wireless Network Adapter when a data
transmission is taking place. Exit your communications program normally, stop
the Adapter if necessary, and then remove the adapter.
