WIRELESS LAN BASICS
Wireless LAN network defined by IEEE 802.11b standard committee could
be configured as :
ƒ
Ad Hoc wireless LAN, or
ƒ
Infrastructure wireless LAN.
Ad Hoc network is a group of PCs installed with wireless LAN cards, this
group of PCs is called a BSS (Basic Service Set). PCs in this group can use
their wireless LAN cards to communicate with each other, but can not
connect to the
Internet .
The most obvious difference between Infrastructure wireless network
and Ad Hoc wireless network is that the PCs in Infrastructure wireless
network can access the resource in the Internet through Access Point .
Depending on your requirement, you can easily set up your PC’s
network to be a “ Ad Hoc ” or “ Infrastructure ” wireless network. Gener-
ally speaking, if in your network, there is an Access Point in it, we recom-
mend you to set your network as an “ Infrastructure ”, so it can connect to
the Internet .
