D-Link wireless products are based on industry standards to provide easy-to-use and compatible high-speed wireless 
connectivity within your home, business, or public access wireless networks. Strictly adhering to the IEEE standard, the D-Link 
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 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.
