Wireless Basics
D-Link wireless products are based on industry standards to provide easyto-use and compatible high-speed wireless connectivity within your home or
business. Strictly adhering to IEEE 802.11a/b/g the D-Link wireless family
of products will allow you to access the data you want, when and where you
want it. No longer will you be limited to one location or forced to run new
wiring through your home or office. You will be able to enjoy the freedom that
wireless networking delivers.
A wireless LAN (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. 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 has proven to be beneficial for many users.
Wireless users can use the same network applications they use on an
Ethernet LAN. Wireless adapter cards used on laptop and desktop systems,
support the same protocols as Ethernet adapter cards. For most users, there
is no noticeable functional difference between a wired Ethernet desktop
computer and a wireless computer equipped with a wireless adapter other
than the added benefit of the ability to roam within the wireless-cell. 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 Access
Point (AP) is a device used to provide this link.
People use wireless LAN technology for many different purposes.
Mobility - Productivity increases when people have access to data in any
location within the operating range of the WLAN. Ad-hoc management
decisions based on real-time information can significantly improve worker
efficiency.
Low Implementation Costs - WLANs are easy to set up, manage, change
and relocate. Networks that frequently change, both physically and logically,
can benefit from WLANs ease of implementation. WLANs can operate in
locations where installation of wiring may be impractical. Furthermore, IEEE
standardization mandates interoperability of all WLAN devices that conform
to the 802.11a/b/g set of standards.

Installation Flexibility - Wireless technology allows the network to go where
wires cannot go.
Installation Considerations
Designed to go up to 1650 feet (~500 meters), D-Link DWL-AG520 lets you
access your network with your computer from virtually anywhere you want.
Keep in mind, however, that the number and thickness of walls, ceilings or
other objects that the wireless signals must pass thru may limit range.
Typical ranges vary depending on the types of materials and background RF
noise in your home or business. The key to maximizing range is to follow
these basic principles:
Keep the number of walls and ceilings between the Access Point and
1.
your receiving device to a minimum - Each wall or ceiling can reduce
your D-Link Wireless product’s range from 3-90 feet (1-30 meters.) For
some businesses or for a large residential home deployment, it may be
beneficial to have more than one access point with overlapping coverage.
2. Be aware of the direct line between Access Points and computers with
wireless adapters - A wall that is 1.5 feet thick (.5 meters), at a 45degree angle appears to be almost 3 feet (1 meter) thick. At a 2-degree
angle it looks over 42 feet (14 meters) thick! Try to make sure that the
Access Points and Adapters are positioned so that the signal will travel
straight through a wall or ceiling for better reception.
3. Building Materials make a difference - A solid metal door or aluminum
studs may have a negative effect on range. Try to position Access Points,
and computers with wireless adapters so that the signal passes through
drywall or open doorways and not other materials.
4. Make sure that the antenna is positioned for best reception by using the
software signal strength tools included with your product.
5. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical
devices or appliances that generate extreme RF noise.
Getting Started
To begin, select the type of wireless network you will be building.
We will discuss the following types of networks in this section:
1. A Home Internet Network
with A Residential Gateway/Router
2. A Home Internet Network with Multiple IP Addresses
3. An Ad Hoc Network
4. An Ad Hoc Network with Internet Sharing
Please select, from the four types of networks described above, the type of
network that is appropriate for your needs. Please follow the instructions in
the corresponding section that follows.
1. A Home Internet Network with A Residential Gateway/Router
(Network administrators with Dynamic IPs can also follow these instructions.)
If you have two or more computers (laptops or desktops) and want to share
files, printers, and Internet access using a DHCP-capable Residential
Gateway/Router – or - if you want to connect to an Ethernet network that
uses Dynamic (DHCP) IP addresses, then follow the instructions on the next
page. When it is complete, your network may look similar to this:
1. A Home Internet Network with A Residential Gateway/Router
DHCP stands for
Dynamic Host
Configuration Protocol.
It is a protocol for
assigning dynamic IP
addresses
“automatically.” With a
DHCP-capable
gateway, there is no
need to manually
assign an IP address.
This type of installation requires that you provide a dynamic IP address for
each computer on your network. You will need a DHCP-capable Residential
Gateway/Router for your network.
