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. D-Link wireless products will allow you access to the data you want,
when and where you want it. Y ou will be able to enjoy the freedom that wireless networking
brings.
A Wireless Local Area Network (WLAN) is a cellular 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 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.
People use WLAN 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 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 fast
and easy and can eliminate the need to pull cable through walls and ceilings. Wireless
technology allows the network to go where wires cannot go - even outside the home or
office.
Scalability – WLANs can be configured in a variety of ways to meet the needs of
specific applications and installations. 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.
Inexpensive Solution - Wireless network devices are as competitively priced as
conventional Ethernet network devices.

Installation Considerations
The D-Link Air DWL-650 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. T ypical 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 the number of walls and ceilings between the DWL-650 and
1
other network devices to a minimum - each wall or ceiling can reduce
your D-Link Air Wireless product’s range from 3-90 feet (1-30 meters.)
Position your 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! Position devices so
that the signal will travel straight through a wall or ceiling (instead of at an
angle) for better reception.
3
Building Materials can impede the wireless signal - 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.

Getting Started
With its default settings, the DWL-650, when activated, will connect
with other D-Link Air products, right out of the box.
There are basically two modes of networking:
Infrastructure – using an Access Point or Router , such as
!
the DI-614+
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-650 wireless
network 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):
A wireless Router - D-Link AirPlus DI-614+
!
A laptop computer with a wireless adapter -

Please remember that D-Link Air wireless devices are pre-configured to connect
together, right out of the box, with their default settings.
For a typical wireless setup at home (as shown above), please do the
following:
You will need broadband Internet access (a Cable or DSL-subscriber line into
your home or office)
Consult with your Cable or DSL provider for proper installation of the modem
Connect the Cable or DSL modem to your broadband router (see the Quick
Installation Guide included with your router.)
Install the D-Link Air DWL-520 wireless PCI adapter into an available PCI slot
on your desktop computer.
(See the Quick Installation Guide included with the DWL-520.)
Install the D-Link Air DWL-650 wireless PC Card adapter into a laptop computer.
(See the Quick Installation Guide included with the DWL-650.)
If you wish, you may connect a computer that is equipped with an Ethernet
network adapter (such as a DFE-530TX+) to the router also.

Getting Started (continued)
Setting up a Wireless Ad Hoc Network
Desktop
Install the Wireless PCI adapter(e.g., DWL-520) into the desktop computer .
(See the Quick Installation Guide included with the product for installation
instructions.)
Install the DWL-650 wireless PC Card adapter into a laptop computer. (See
the Quick Installation Guide included with the product.)
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)
IP Address
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.
IMPORT ANT : If computers or other devices are assigned the same IP Address,
one or more of the devices may not be visible on the network.
