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 wireless LAN PC card called a
BSS (Basic Service Set). These notebooks use their wireless LAN PC cards to
communicate with each other, and notebooks cannot connect to the Internet.
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.
