Introduction
*Not all servers can provide Authentication
The DWL-AG530 has the newest, strongest and most advanced security
features available today. When used with other 802.11 WPA (Wi-Fi Protected
Access) and 802.1X compatible products in a network with a RADIUS server,
the security features include:
WPA: Wi-Fi Protected Access which authorizes and identifies users based
on a secret key that changes automatically at regular intervals. WPA
uses TKIP (Temporal Key Integrity Protocol) to change the temporal
key every 10,000 packets (a packet is a kind of message transmitted
over a network.) This ensures much greater security than the standard
WEP security. (By contrast, the previous WEP encryption
implementations required the keys to be changed manually.)
802.1X: Authentication which is a first line of defense against intrusion. In the
authentication process, the Authentication Server* verifies the identity
of the client attempting to connect to the network. Unfamiliar clients
would be denied access.
For home users that will not incorporate a RADIUS server in their network, the
security for the DWL-AG530, used in conjunction with other WPA-compatible
802.11 products, will still be much stronger than ever before. Utilizing the Pre-
Shared Key mode of WPA, the DWL-AG530 will obtain a new security key
every time it connects to the 802.11 network. You only need to input your
encryption information once in the configuration menu. No longer will you have
to manually input a new WEP key frequently to ensure security. With the DWL-
AG530,you will automatically receive a new key every timeyou connect,vastly
increasing the safety of your communication.
At up to fifteen times the speed of previous wireless devices (up to 108Mbps in
SuperAGmode),youcanworkfasterandmoreefficiently,increasingproductivity.
With the DWL-AG530, bandwidth-intensive applications like graphics or
multimediawill benefit significantly because large files are able tomove across
the network quickly.
Inclusion of all three standards (802.11g; 802.11a; 802.11b) means that the
DWL-AG530 is versatile enough to allow connection to almost any 802.11
network or device, and the removable antenna allows for easy installation of
the DWL-AG530 into the PCI slot.

D-Link wireless products are based on industry standards to provide easy-to-
useandcompatiblehigh-speedwirelessconnectivitywithin your home,business
or public access wireless networks. D-Link wireless products will allow you
access to the data you want, when and where you want it. You will be able to
enjoy the freedom that wireless networking brings.
A wireless local area network (WLAN) is a computer network that transmits
and receives data with radio signals instead of wires. WLANs 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 Basics
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.

Wireless Basics (continued)
People use WLAN technology for many different purposes:
Mobility – Productivity increases when people have access to data in any
locationwithin the operatingrange of the WLAN. Managementdecisions 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 can benefit from WLANs ease
of implementation. WLANs can operate in locations where installation of wiring
may be impractical.
Installation and Network Expansion - Installing a WLAN system can be
fastandeasyandcaneliminatetheneedtopullcablethroughwallsandceilings.
Wireless technology allows the network to go where wires cannot go - even
outside the home or office.
Inexpensive Solution –Wireless network devices are as competitively priced
as conventional Ethernet network devices.
Scalability –WLANs can be configured in a varietyof waysto meet the needs
ofspecificapplications and installations.Configurations are easilychanged and
rangefrom Peer-to-Peer networkssuitable for asmall number ofusers to larger
Infrastructure networks to accommodate hundreds or thousands of users,
depending on the number of wireless devices deployed.

Standards-Based Technology
The DWL-AG530 Wireless PCI Adapter utilizes the 802.11a, 802.11b and
802.11g standard.
TheIEEE802.11g standardisanextensionofthe802.11b standard.Itincreases
thedatarateup to 54 Mbps within the 2.4GHz band utilizing OFDM technology.
Thismeans that inmost environments, within the specifiedrange of thisdevice,
you will be able to transfer large files quickly or even watch a movie in MPEG
format over your network without noticeable delays. This technology works by
transmittinghigh-speeddigitaldataoveraradiowaveutilizingOFDM (Orthogonal
FrequencyDivisionMultiplexing) technology.OFDM works by splittingthe radio

range possible.
Wireless Basics (continued)
802.11g offers the most advanced network security features available today,
including: WPA, 802.1x, TKIP,AES and Pre-Shared Key mode.
The DWL-AG530 is backwards compatible with 802.11b devices. This means
that if you have an existing 802.11b network, the devices in that network will be
compatible with 802.11g devices at speeds up to 11Mbps in the 2.4GHz range.

Installation Considerations
Keep your product away (at least 3-6 feet or 1-2 meters) from electrical
devices or appliances that generate RF noise.
4
Keep the number of walls and ceilings between the DWL-AG530 and
other network devices to a minimum - each wall or ceiling can reduce
your DWL-AG530’s range from 3-90 feet (1-30 meters.) Position your
devices so that the number of walls or ceilings is minimized.
1
Be aware of the direct line between network devices.Awall that is 1.5
feet thick (.5 meters), at a 45-degree angle appears to be almost 3 feet
(1 meter) thick. At a 2-degree angle it looks over 42 feet (14 meters)
thick! Position devices so that the signal will travel straight through a
wall or ceiling (instead of at an angle) for better reception.
2
Building materials can impede the wireless signal - a solid metal door
oraluminum studs may havea negative effectonrange.Try to position
wireless devices and computers with wireless adapters so that the
signalpasses throughdrywalloropendoorwaysandnotothermaterials.

The D-Link AirPremierTM AG DWL-AG530 lets you access your network, using
a wireless connection, from virtually anywhere within its operating range. Keep
in mind, however, that the number, thickness and location of walls, ceilings, or
other objects that the wireless signals must pass through, may limit the range.
Typical ranges vary depending on the types of materials and background RF
(radio frequency) noise in your home or business. The key to maximizing
wireless range is to follow these basic guidelines:

Getting Started
Infrastructure – using an access point or wireless router
such as the DWL-7100AP.
Ad-Hoc – directly connecting to another computer, for Peer-
to-Peer communication, using wireless network adapters on
each computer, such as two or more DWL-AG530 Wireless
PCIAdapters.
On the following pages we will show you an example of an Infrastructure
Network and an Ad-Hoc Network.
An Infrastructure network contains an access point or a wireless router.
The Infrastructure Network example shown on the following page contains
the following D-Link network devices (your existing network may be
comprised of other devices):
A wireless router - D-Link AirPremier DI-784
A laptop computer with a wireless adapter -
D-Link Air Premier DWL-AG660
A desktop computer with a wireless adapter -
D-Link Air Premier AG DWL-AG530
A Cable modem - D-Link DCM-201
