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 ofce environments, and public areas such

as airports, coffee shops and universities. Innovative ways to utilize WLAN technology are helping people to work and

communicate more efciently. Increased mobility and the absence of cabling and other xed infrastructure have proven

to be benecial 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.
