Wireless Basics

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 and conveniently access your network. 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 oice environments, and public areas such as airports, cofee shops
and universities. Innovative ways to utilize WLAN technology are helping people to work and communicate more eiciently.
Increased mobility and the absence of cabling and other ixed infrastructure have proven to be beneicial for many users.
Wireless users can use the same applications they use on a wired network. Wireless adapters 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.
