Introduction

The D-Link AirPlusXtreme GDWL-2000AP High-Speed Wireless Access Point is a

draft 802.11g high-performance, wireless access point that supports high-speed wireless

networking at home, at work or in public places.

The DWL-2000AP is capable of operating in one of 4 different modes to meet your

wireless networking needs. The DWL-2000AP can operate as an Access Point; in Access

Point-to-Access Point Bridging mode; Access Point-to-Multipoint Bridging mode; or

Wireless Client mode.

The DWL-2000AP is an ideal solution for quickly creating and extending a wireless local

area network (WLAN) in offices or other workplaces, trade shows and special events.

* Available Spring 2003 as a free download

Unlike most access points, the DWL-2000AP provides data transfers at up to 54 Mbps

(compared to the standard 11 Mbps) when used with other D-Link AirPlusXtremeG

products. The 802.11g standard is backwards compatible with 802.11b products. This

means that you do not need to change your entire network to maintain connectivity. You

may sacrifice some of 802.11g’s speed when you mix 802.11b and 802.11g devices, but

you will not lose the ability to communicate when you incorporate the 802.11g standard

into your 802.11b network. You may choose to slowly change your network by gradually

replacing the 802.11b devices with 802.11g devices .

Authentication is a first line of defense against intrusion. In the

Authentication process the server verifies the identity of the client attempting

to connect to the network.Unfamiliar clients would be denied access.

In addition to offering faster data transfer speeds when used with other 802.11g products,

the DWL-2000AP has the newest, strongest, most advanced security features available

today. When used with other 802.11g WPA (WiFi Protected Access) and 802.1x

compatible products in a network with a RADIUS SERVER, the security features include:

WPA:*

802.1x:

A new security feature, Wi-Fi Protected Access authorizes and identifies

users based on a secret key that changes automatically at a regular

interval. WPA uses TKIP (Temporal Key Integrity Protocol) to change

the temporal key every 10,000 packets (a packet is a kind of message

transmitted over a network.) This insures much greater security than the

standard WEP security. (By contrast, the older WEP encryption required

the keys to be changed manually.)

Connections

Ethernet Port

When connecting

to a non-wireless

router you will need

to use a Cross-

Over Cable; when

connecting to an

Ethernet-enabled

computer you will

need to use a

Straight-Through

Cable.

Receptor

Adapter

Pressing the

Reset Button

original factory

default settings.

LEDs

LED stands for Light-Emitting Diode. The DWL-2000AP Wireless Access Point has 3

LEDs as shown below:

Power: Solid green light indicates connection

WLAN: Blinking green light indicates wireless activity;

solid green light indicates connection

LAN: Blinking green light indicates activity

on the Ethernet Port; solid green light

indicates connection

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, with-

out a RADIUS SERVER, will obtain a new security key

every time he or she connects to the network, vastly im-

proving 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.

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.

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.

The DWL-2000AP is compatible with the following wireless products:

D-Link AirPlus DWL-650+,D-Link AirPlus XtremeG DWL-G650

Wireless Cardbus Adapters used with laptop computers

D-Link AirPlus DWL-520+, D-Link AirPlus XtremeG DWL-G520

Wireless PCI cards used with desktop computers

Standards-Based Technology

The DWL-2000AP Wireless Access Point utilizes the new 802.11g 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 (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 DWL-2000AP will

automatically sense the best possible connection speed to ensure the greatest

speed and range possible.

802.11g offers the most advanced network security features available today,

including: WPA , 802.1x, 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.

Wireless Basics (continued)

WPA will be available Spring 2003 as a free download

802.11g standard is scheduled for ratification by IEEE Summer 2003
