Features
Better security with WPA* and 802.1x*
TKIP
(Temporal Key Integrity Protocol), in conjunction with
a RADIUS SERVER, changes the temporal key every
10,000 packets, ensuring greater security
Pre Shared Key
mode means that the home user, without
a RADIUS SERVER, will obtain a new security key every
time he or she connects to the network, vastly improving
the safety of communications on the network.
Compatible with the 802.11b standard
to provide a wireless data rate of up to
11Mbps - that means you can migrate your system to the 802.11g standard
on your own schedule without sacrificing connectivity.
Faster wireless networking
with the draft 802.11g standard to provide a wireless
data rate of up to 54Mbps*
* Available Spring 2003 as a free download
Web-based interface
for Managing and Configuring
Easy Installation
with the Setup Wizard
Operates in the 2.4GHz frequency range
802.1x* Authentication
in conjunction with the RADIUS SERV-
ER verifies the identity of would be clients
WPA*
(Wi Fi Protected Access) authorizes and identifies users
based on a secret key that changes automatically at a regular
interval
4 Different Operation modes -
Capable of operating in one of four different operation
modes to meet your wireless networking requirements: Access Point; AP-to-AP
Bridging; AP-to-Multipoint Bridging; and Wireless Client.
*Maximum wireless signal rate based on IEEE Standard 802.11g specifications. Actual data throughput will
vary. Network conditions and environmental factors, including volume of network traffic, building materials
and construction and network overhead lower actual data throughput rate.

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 wherever a wireless network is available. 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 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 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.
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 Access Point
is a device that can be used to provide this link.

Wireless Basics
(continued)
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, both physically and logically,
can benefit from a WLAN’s 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.

Standards-Based Technology
The
DWL-2000AP Wireless Access Point utilizes the new
802.11g
1
standard.
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
(
O
rthogonal
F
requency
D
ivision
M
ultiplexing) 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 DWL-2000AP will automatically
sense the best possible connection speed to ensure the greatest speed and
range possible.
802.11g
3
offers the most advanced network security features available today,
including: WPA
2
, 802.1x
3
,
TKIP, AES and Pre-Shared Key mode.
These security
features are explained in more detail in the Introduction and the Features section
of this manual.
The DWL-2000AP 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 of up to 11Mbps in the 2.4GHz
range.
