At up to fteen times the speed of previous wireless devices (maximum

wireless signal rate of up to 108Mbps* in Super G mode), you can

work faster and more efciently, increasing productivity. With the

DWL-2200AP, bandwidth-intensive applications like graphics or

multimedia will benefit significantly because large files are able to

move across the network quickly.

The DWL-2200AP is capable of operating in one of 3 different wireless

networking modes; access point, WDS (Wireless Distribution System)

with AP, or WDS mode.

Use less wiring, enjoy increased exibility, save time and money with

PoE (Power over Ethernet). With PoE, the DWL-2200AP shares power

and data over the CAT5 cable, making the setup of your network less

expensive and more convenient.

An ideal solution for quickly creating and extending a wireless local

area network (WLAN) in ofces or other workplaces, trade shows and

special events, the DWL-2200AP provides data transfers at up to

108Mbps in Super G mode when used with other D-Link AirPremier™

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

devices.)

Introduction

* Maximum wireless signal rate derived from IEEE Standard 802.11g specications. Actual

data throughput will vary. Network conditions and environmental factors, including volume of

network trafc, building materials and construction, and network overhead, lower actual data

throughput rate. Environmental factors may adversely affect wireless signal range.

WPA is offered in two avors: Enterprise (used for corporations) and

Personal (used for home users).

WPA-Personal and WPA2-Personal is directed at home users who do

not have the server based equipment required for user authentication.

The method of authentication is similar to WEP because you dene

a “Pre-Shared Key” on the wireless router/AP. Once the pre-shared

key is confirmed and satisfied on both the client and access point,

then access is granted. The encryption method used is referred to as

the Temporal Key Integrity Protocol (TKIP), which offers per-packet

dynamic hashing. It also includes an integrity checking feature which

ensures that the packets were not tampered with during wireless

transmission. WPA2-Personal is far superior to WPA-Personal,

because the encryption of data is upgraded with the Advanced

Encryption Standard (AES).

802.1x: Authentication which is a first line of defense against

intrusion. In the authentication process, the Authentication Server

veries the identity of the client attempting to connect to the network.

Unfamiliar clients would be denied access.

EAP (Extensible Authentication Protocol) is available through the

Windows®XP operating system. You will need to use the same type

of EAP protocol on all devices in your network when using the 802.1x

feature.

WPA-Enterprise and WPA2-Enterprise is ideal for businesses

that have existing security infrastructures in place. Management

and security implementation can now be centralized on a server

participating on the network. Utilizing 802.1x with a RADIUS (Remote

Authentication Dial-in User Service) server, a network adminstrator

can define a list of authorized users who can access the wireless

LAN. When attempting to access a wireless LAN with WPA-Enterprise

or WPA2-Enterprise configured, the new client will be challenged

with a username and password. If the new client is authorized by

the administration, and enters the correct username and password,

then access is granted. In a scenario where an employee leaves the

company, the network administrator can remove the employee from

the authorized list and not have to worry about the network being

compromised by a former employee. WPA2-Enterprise is far superior

to WPA-Enterprise, because the encryption of data is upgraded

with the Advanced Encryption Standard (AES).

3 Different Operation modes - Capable of operating in

one of three different operation modes to meet your wireless

networking requirements: Access Point; WDS with AP, or WDS.

Easy Installation with PoE (Power over Ethernet).

Faster wireless networking with the 802.11g standard to

provide a maximum wireless signal rate of up to 54Mbps*

(maximum wireless signal rate of up to 108Mbps* in Super G

mode).

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

sacricing connectivity.

Better security with WPA - The DWL-2200AP can securely

connect wireless clients on the network using WPA (Wi-Fi

Protected Access) providing a much higher level of security

for your data and communications than has previously been

available.

AP Manager Setup Wizard - The new Setup Wizard makes

network conguration quick and simple.

SNMP for Management - The DWL-2200AP is not just fast but

it also supports SNMP v.3 for a better network management.

Superior wireless AP manager software is bundled with the

DWL-2200AP for network conguration and rmware upgrade.

Systems administrators can also setup the DWL-2200AP easily

with the Web-based configuration. A D-Link D-View module

will be downloadable for network administration and real-time

network trafc monitoring with D-Link D-View software.

Utilizes OFDM technology (Orthogonal Frequency Division

Multiplexing).

Operates in the 2.4GHz frequency range.

Web-based interface for managing and conguring.

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. You 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 for

many users.

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.

Inexpensive Solution - Wireless network devices are as competitively

priced as conventional Ethernet network devices. The DWL-2200AP

saves money by providing multi-functionality, conﬁgurable in one of four

different modes.

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.

Standards-Based Technology

The DWL-2200AP Managed Wireless Access Point 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 maximum wireless signal rate of up to 54Mbps* (maximum

wireless signal rate of up to 108Mbps* in Super G mode) 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 les 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-2200AP 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 and WPA2.

*”Maximum wireless signal rate derived from IEEE Standard 802.11g speciﬁcations. Actual

network trafﬁc, building materials and construction, and network overhead lower actual data

throughout rate.”

The D-Link DWL-2200AP 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. 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:

Keep your product away (at least 3-6 feet or 1-2 meters) from

electrical devices or appliances that generate RF noise.

Keep the number of walls and ceilings between the DWL-2200AP

and other network devices to a minimum - each wall or ceiling can

reduce your DWL-2200AP’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 (.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.

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.
