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.   
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. 
What is Wireless?   
Wireless or Wi-Fi technology is another way of connecting your computer to the network without using wires. Wi-Fi uses radio frequency to connect 
wirelessly, so you have the freedom to connect computers anywhere in your home or office network.

How does wireless work? 
Wireless works similar to how cordless phone work, through radio signals to transmit data from one point A to point B. But wireless technology has 
restrictions as to how you can access the network. You must be within the wireless network range area to be able to connect your computer. There 
are two different types of wireless networks Wireless Local Area Network (WLAN), and Wireless Personal Area Network (WPAN).
