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 networking differs from ad-hoc networking

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

USB Wireless Network Adapter User’s Manual

point can manage the bandwidth to maximize

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 range: 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.
