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 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 to 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
within the operating range of the WLAN. Management decisions based on real-time
information can significantly improve worker efficiency .
- Productivity increases when people have access to data in any location
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.
Inexpensive Solution - Wireless network devices are as competitively priced as
conventional Ethernet network devices.
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.

D-Link AirPlus G DWL-G520 and DWL-G510
Wireless PCI cards used with desktop computers
D-Link AirPlus G DWL-2000AP
Enhanced 2.4GHz Wireless Access Point
D-Link AirPlus G DI-624
Wireless Router

Standards-Based Technology
The DWL-G630 Wireless Cardbus Adapter utilizes the 802.11b and the 802.11g standards.
The IEEE 802.11g standard is an extension of the 802.11b standard. It increases the
data rate up to 54 Mbps within the 2.4GHz band, utilizing OFDM technology .
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. The D-Link DWLG630 will automatically sense the best possible connection speed to ensure the greatest
speed and range possible.
The DWL-G630 is backwards compatible with 802.1 1b devices. This means that if you
have an existing 802.11b network, the devices in that network will be compatible with
802.1 1g devices at speeds up to 1 1Mbps in the 2.4GHz range.

Wireless Basics (continued)
Installation Considerations
The D-Link AirPlus G DWL-G630 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:
1
Keep the number of walls and ceilings between the DWL-G630 and other network
devices to a minimum - each wall or ceiling can reduce your DWL-G630’s range
from 3-90 feet (1-30 meters.) Position your devices so that the number of walls
or ceilings is minimized.
Be aware of the direct line between network devices. A wall that is 1.5 feet thick
2
(.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
There are basically two modes of networking:
Infrastructure – using an access point, or wireless router, such as
the DI-624.
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-G630 Wireless Cardbus 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 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 AirPlus Xtreme G DI-624
A laptop computer with a wireless adapter -
D-Link AirPlus G DWL-G630
A desktop computer with a wireless adapter -
D-Link AirPlus G DWL-G520 or DWL-G510

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.
