1. Introduction
Welcome to the world of wireless computer networks.
This document is a short reference guide that will show
you how you can:
• Use WLAN Cardbus adapters to connect the mobile
computers to a wireless network.
• Use mobile computers to roam between different
locations without losing the wireless connection.
• Use the wireless network to share files and printers
with other computer users.
In a Local Area Network (LAN), you can connect two or more computers to each
other. You can use a network to share files or common equipment such as a
printer or a modem. In a wired network, you need special cables and networking
equipment to connect the computers, but in a wireless network, computers
communicate via radio technology that can pass through walls and ceilings.
Users connect the wireless computers by assigning a shared Network Name
value to each Wireless Client Adapter that belongs to your network.
To secure your WLAN Cardbus adapter supports Data Encryption when you
transmit data, we recommend that you always enable this feature to protect your
network against unauthorized access to your files and communications.
The WLAN Cardbus adapter support different network modes such as Peer-toPeer Group, Act as Base Station, and Base Station Network that allow users to
connect to an existing network or start the network.
For instructions to install your WLAN Cardbus adapter, please consult the
documentation that is included with the hardware.
1.1 The Network Type
Peer-to-Peer Group
Network where Wireless Client devices communicate directly with each other as
the following figure shows.
Act as Base Station
Network where you assign one computer to act as the central point of
communication for all wireless computers. The computer in this mode will start
it's own wireless network. This type of network for SOHO or small offices
provides a larger wireless range than a Peer-to-Peer Group. However you can
assign only one computer to act as Base Station.
Base Station Network
Network where Wireless Client devices communicate with each other through
a dedicated Base Station.
With this type of network for medium to large enterprises, you can add as many
Base Station devices as you like to extend the wireless range. Most Base Station
devices also allow you to connect your wireless network to a wired network
infrastructure.
