1. Introduction
Thank you for purchasing your Wireless Local Area Net (WLAN) USB
Dnogle. You are about to install a networking system that is not only fast and
powerful, but also easy to set up and simple to maintain. In a short time you
and those in your network will be able to share a local printer and files,
access the Internet, and roam about the office wire -free.
Using radio frequency (RF) technology, WLANs transmit and receive
data over the air, minimizing the need for wired connections. Thus, WL ANs
combine data connectivity with user mobility, and, through simplified
configuration, enable movable LANs.
This wireless networking solution has been designed for both large and
small businesses, and it is scalable so that you can easily add more users
and new network features as your business grows.

2. Wireless LAN basics
Wireless LAN network defined by IEEE 802.11b standard committee could be
configured as:
•• Ad Hoc wireless LAN or
•• Infrastructure wireless LAN
Ad Hoc network is a group of notebooks with WLAN PC cards or USB dongles
called a BSS (Basic Service Set). These notebooks use their WLAN PC cards or USB
dongles to communicate with each other, and notebooks can not connect to the
Internet.
Figure 2-1 Ad Hoc wireless network
The most obvious differentiation between Infrastructure wireless network and Ad
Hoc wireless network is that the notebooks in Infrastructure wireless network can
make use of the resource in the Internet through Access Point.

To set up your notebook’s network as the type of “Ad Hoc” or “Infrastructure ”
wireless network depends completely on your requirement. Generally, if your network
environment has an Access Point, we recommend that you set it as “Infrastructure ”
to connect to the Internet.
