Introduction  
The 802.11b Wireless 32bit CardBus PC Card 
is a device that lets you connect your notebook to 
a wireless local area network (LAN).    A wireless 
LAN is like a regular LAN, except that you can 
share information without looking for a place to 
plug in, and augment networks without installing 
or moving wires.    Based on radio frequency (RF) 
technology, a wireless LAN transmits and 
receives data over the air, along with the 
guarantee to provide privacy and noninterference 
by the use of separate radio frequency. 
The 802.11b Wireless 32bit CardBus PC Card 
allows you to take full advantage of your PC’s 
mobility with access to real-time information and 
online services anytime and anywhere.  Plus, 
with the network installation simplicity and 
flexibility, you can eliminate the need to pull 
cable through walls and ceilings and allow the 
network to go where wires cannot go.    Exploring 
WWW and augmenting networks can never be 
done more easily
