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.

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.

How does wireless work?

Wireless works similar to how cordless phone work, through radio signals to transmit data from 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).

Wireless Local Area Network (WLAN)

In a wireless local area network, a device called an Access Point (AP) connects computers to the network. The DHP-W610AV has a small antenna
attached to it, which allows it to transmit data back and forth over radio signals. With an indoor Access Point as seen in the picture, the signal can
travel up to 300 feet. With an outdoor Access Point the signal can reach out up to 30 miles to serve places like manufacturing plants, industrial
locations, college and high school campuses, airports, golf courses, and many other outdoor venues.
