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

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.
to utilize WLAN technology are helping people to work and communicate
7
Wireless Basics (continued)
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. Management decisions based
on real-time information can significantly improve worker efficiency.
Low Implementation Costs WLANs (Wireless Local Area Networks) 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.
Installation Speed and Simplicity - Installing a wireless LAN system can
be fast and easy and can eliminate the need to pull cable through walls and
ceilings.
Network Expansion - Wireless technology allows the network to go
where wires cannot.
Scalability – Wireless Local Area Networks (WLANs) can be configured in a
variety of topologies to meet the needs of specific applications or existing
infrastructures. Configurations are easily changed and range from peer-to-
peer networks suitable for a small number of users to larger infrastructure
networks to accommodate hundreds or thousands of users, depending on the
number of wireless devices deployed.

The DWL-AB520 is compatible with other D-Link AirPro 802.11a products,
which include:
5GHz Wireless Cardbus Adapters used with laptop computers
(DWL-A650)
5GHz Multimode Wireless Broadband Routers computers (DI-764,
and DI-754)
5GHz Wireless Access Points (DWL-5000AP, DWL-6000AP)
The DWL-AB520 is also compatible with D-Link Air and AirPlus 802.11b
wireless products, which include:
2.4GHz Wireless Cardbus Adapters used with laptop computers
(DWL-650, DWL-650+)
2.4GHz Wireless PCI cards used with desktop computers
(DWL-520, DWL-520+)
Enhanced 2.4GHz Wireless Access Point (DWL-900AP+)
Enhanced 2.4GHz Wireless Broadband Router (DI-614+)
Standards-Based Technology
The versatile DWL-AB520 Wireless Multimode PCI Adapter integrates both
802.11a and 802.11b standards into a single unit.
The IEEE 802.11a standard designates that devices may operate at an optimal
data rate of 54 Mbps (72 Mbps in proprietary Turbo mode.) This means that in
most environments, within the specified range of this device, 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 transmitting high-
speed digital data over a radio wave utilizing OFDM (Orthogonal Frequency
Division Multiplexing) technology. OFDM works by splitting the radio signal
into multiple smaller sub-signals that are then transmitted simultaneously at
different frequencies to the receiver. OFDM reduces the amount of crosstalk
(interference) in signal transmissions. D-Link AirPro 802.11a products will
automatically sense the best possible connection speed to ensure the greatest
speed and range possible.
Based on the IEEE 802.11b standard, the DWL-AB520 is also interoperable
with existing compatible 2.4GHz wireless technology with data transfer speeds
of up to 11Mbps.

Installation Considerations
The D-Link AirPro DWL-AB520 lets you access your network, using a wireless
connection, from virtually anywhere. 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:
1.
Keep the number of walls and ceilings between the DWL-AB520 and
other network devices to a minimum - each wall or ceiling can reduce
your D-Link AirPro Wireless product’s range from 3-90 feet (1-30 meters.)
Position your receiving devices so that the number of walls or ceilings is
minimized.
2. 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! Try to make sure that devices 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 wireless
devices and computers with wireless adapters so that the signal passes
through drywall or open doorways and not other materials.
4. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical
devices or appliances that generate RF noise.

There are basically two modes of networking:
Infrastructure – using an Access Point, such as the DWL-900AP+,
DWL-5000AP or DWL-6000AP.
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-AB520 wireless network PCI adapters.
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 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):

Getting Started
Setting up a Wireless Ad Hoc Network
Install the D-Link AirPro DWL-AB520 Wireless Network adapter
into the desktop computer.
See the Quick Installation Guide included
with the product for installation instructions.
Install a wireless network adapter into the laptop computer. In the
example above the DWL-A650, DWL-650+ or DWL-650 may be
installed into a laptop computer.
See the Quick Installation Guide

Set the wireless configuration for the adapters to Ad-Hoc mode, set
the adapters to the same channel, and assign an IP Address to
each computer on the Ad-Hoc network.
(See Box below)
When assigning IP Addresses to the computers on the network, please
remember that the IP Address for each computer must be in the same
IP Address range as all the computers in the network, and the subnet
mask must be exactly the same for all the computers in the network.
For example: If the first computer is assigned an IP Address of 192.168.0.2
with a Subnet Mask of 255.255.255.0, then the second computer can be
assigned an IP Address of 192.168.0.3 with a Subnet Mask of 255.255.255.0,
etc.
IMPORTANT: If computers or other devices are assigned the same IP
Address, one or more of the devices may not be visible on the network.
