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 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 office 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 efficiently. Increased mobility and the absence of cabling and other
fixed infrastructure have proven to be beneficial 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.
