At up to ﬁfteen 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 efﬁciently,

increasing productivity. With the DWL-3200AP, bandwidth-intensive applications like

graphics or multimedia will beneﬁt signiﬁcantly because large ﬁles are able to move

across the network quickly.

The DWL-3200AP 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 ﬂexibility, save time and money with PoE (Power over

Ethernet). With PoE, the DWL-3200AP 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 ofﬁces or other workplaces, trade shows and special events, the DWL-3200AP

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 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 throughout rate.”

WPA is offered in two ﬂavors: 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 deﬁne 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 veriﬁes 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).

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-3200AP 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.

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.

Standards-Based Technology

The DWL-3200AP 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 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-3200AP 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.

Wireless Basics

The D-Link AirPremier DWL-3200AP 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-3200AP and other network

devices to a minimum - each wall or ceiling can reduce your DWL-3200AP’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.
