Introduction
*Not all servers can provide Authentication
TheDWL-AG530has the newest, strongestandmost advancedsecurityfeatures
available today. When used with other 802.11 WPA/WPA2 (Wi-Fi Protected
Access/Wi-Fi Protected Access 2TM) and 802.1X compatible products in a
network with a RADIUS server, the security features include:
WPA/WPA2: Wi-Fi Protected Access/Wi-Fi Protected Access 2TM which
authorizesandidentifiesusers basedon asecretkey thatchangesautomatically
atregular intervals. WPA/WPA2 usesTKIP(Temporal Key Integrity Protocol)
tochangethe temporalkey every 10,000packets(apacketis a kindofmessage
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/WPA2-
compatible802.11 products, willstillbemuch stronger thaneverbefore.Utilizing
the Pre- Shared Key mode of WPA/WPA2, theDWL-AG530 will obtain a new
security key every time it connects to the 802.11 network. You only need to
inputyour encryptioninformationoncein the configurationmenu.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 time you
connect, vastly increasing the safety of your communication.
At up to fifteen times the speed of previous wireless devices (up to 108Mbps in
SuperAGmode),youcanwork fasterandmore efficiently,increasingproductivity.
With the DWL-AG530, bandwidth-intensive applications like graphics or
multimedia will benefit significantly because large files are able to move 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.

D-Link wireless products are based on industry standards to provide easy-to-
useandcompatiblehigh-speedwirelessconnectivitywithinyourhome,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 theoperating rangeof the WLAN. Managementdecisionsbased
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 fromWLANs 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
fast andeasyandcaneliminatethe need topullcablethrough walls andceilings.
Wireless technology allows the network to go where wires cannot go - even
outside the home or office.
Inexpensive Solution –Wireless network devicesare ascompetitively priced
as conventional Ethernet network devices.
Scalability –WLANs can be configured in a variety of ways to meet the needs
ofspecific applications andinstallations. Configurations are easily changedand
rangefrom Peer-to-Peer networkssuitablefora smallnumber of usersto larger
Infrastructure networks to accommodate hundreds or thousands of users,
depending on the number of wireless devices deployed.

Standards-Based Technology
TheDWL-AG530WirelessPCIAdapterutilizesthe 802.11a,802.11b and 802.11g
standard.
TheIEEE 802.11g standardisanextensionof the 802.11b standard.It increases
the data rate up to 54 Mbps within the 2.4GHz band utilizing OFDM technology.
Thismeansthat in most environments,withinthe 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
Frequency DivisionMultiplexing)technology. OFDM works by splitting the radio
signalintomultiplesmaller sub-signalsthat are thentransmittedsimultaneously
atdifferent frequencies to thereceiver. OFDM reducesthe amount of crosstalk
(interference)insignal transmissions.TheD-LinkDWL-AG530 willautomatically
sense the best possible connection speed to ensure the greatest speed and
range possible.
Wireless Basics (continued)
802.11g offers the most advanced network security features available today,
including: WPA, WPA2, 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
TheD-Link AirPremier AGDWL-AG530 lets you access your network, using a
wirelessconnection,from virtually anywherewithin its operatingrange. Keepin
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:
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.A wall 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 have a negativeeffectonrange.Trytoposition

passes through drywall or open doorways and not other materials.
