wireless family of products will allow you to securely access the data you want, when and where you want it. You will be able 
to enjoy the freedom that wireless networking delivers.
A wireless local area network (WLAN) is a cellular computer network that transmits and receives data with radio signals instead of 
wires. Wireless LANs are used increasingly in both home and oce environments, and public areas such as airports, coee shops 
and universities. Innovative ways to utilize WLAN technology are helping people to work and communicate more eciently. 
Increased mobility and the absence of cabling and other xed infrastructure have proven to be benecial for many users. 
Wireless users can use the same applications they use on a wired network.  Wireless adapter cards used on laptop and desktop 
systems support the same protocols as Ethernet adapter cards. 
Under many circumstances, it may be desirable for mobile network devices to link to a conventional Ethernet LAN in order to 
use servers, printers or an Internet connection supplied through the wired LAN.  A wireless router is a device used to provide 
this link.
