ture Mode) or another 802.11a, 802.11b, or 802.11g wireless adapter (for Ad-Hoc; Peer-to-Peer networking mode).
The D-Link AirXpertT DWL-AG650
Tri-mode Dualband Wireless Cardbus Adapter is an
802.11a/802.11b/draft 802.11g high-performance, wireless adapter that supports high- speed wireless networking at home, at work or in public places.
Featuring a breakthrough all-in-one tri-mode dualband design, the new D-Link AirXpert DWL-AG650 is a next generation laptop PC adapter that connects to 802.11a (in the 5GHz band) and draft 802.11g networks (in the 2.4GHz band) at 54 Mbps and 802.11b networks (in the 2.4GHz band) at 11Mbps.
When used with other 802.11a or 802.11g devices, the DWL-AG650 will achieve data transfer rates of up to 54Mbps. 802.11b devices will communicate at 11Mbps.
In addition to offering faster data transfer speeds when used with other 802.11a or draft 802.11g products, the DWL-AG650 has the newest, most advanced security features available today, using the draft 802.11i security standard. These additional security features are optional. You may choose to continue using the familiar WEP security, or you may not wish to utilize security features at all. However, if you do choose to use the DWL-AG650â€™s powerful security features with other WPA (WiFi Protected Access) and 802.1x compatible products in a network with a RADIUS server, the security features will include: WPA*: 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 ensures much greater security than the standard WEP security. (By contrast, the older WEP encryption required the keys to be changed manually). 802.1x: 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.
Users that choose not to incorporate a RADIUS server in their network may also use the optional enhanced security features, or they may wish to continue using the standard WEP security, or they may choose to use no security at all. However, if you do wish to experience the enhanced security of the DWL-AG650 in conjunction with other draft 802.11i compatible products, without a RADIUS server, the Pre Shared Key mode of WPA will assign a new security key every time the DWL-AG650 connects to the draft 802.11i Access Point. If you choose to enable the enhanced security features of the DWL-AG650, you need only to input your encryption information once in the configuration menu. No longer will you have to manually change the WEP key to ensure security - with the DWL-AG650, you will automatically receive a new key every time you connect, vastly increasing the safety of your communications. *WPA will be available Q3 2003 as a driver download

5 Wireless Basics
D-Linkwireless 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 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 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.
6 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 â€“ 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 â€“ Wireless network devices are as competitively priced as conventional Ethernet network devices. Scalability â€“ 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. The DWL-AG650 is compatible with the following wireless products:
! D-LinkAirPro DWL-A650, D-Link AirPlus DWL-650+, D-Link AirPlus Xtreme G DWL-G650, D-Link AirPro DWL-AB650 Wireless Cardbus Adapters used with laptop computers
! D-LinkAirPro DWL-A520 and D-Link AirPlus DWL-520+, D-Link AirPlus Xtreme G DWL-G520, D-Link AirXpert DWL-AG520, and D-Link AirPro DWL-AB520 Wireless PCI cards used with desktop computers

7 Wireless Basics (continued) Standards-Based Technology
The DWL-AG650 Wireless Cardbus Adapter utilizes the 802.11a, 802.11b and1 draft 802.11g st 1
The IEEE draft 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. The 802.11a standard also increases the data rate up to 54 Mbps, but within the 5GHz band. Both 802.11a and 802.11g utilize 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-AG650 will automatically sense the best possible connection speed to ensure the greatest speed and range possible.
The DWL-AG650 offers the most advanced network security features available today, including: WPA , 802.1x and 2 AES hardware support 3
In addition to its compatibility with 802.11g and 802.11a devices, the DWL- AG650 is compatible with 802.11b devices. This means that if you have an existing 802.11b network, or a network with a mixture of 802.11g, 802.11a and 802.11b, the devices in that network will be compatible with the DWL-AG650. 1 802.11g standard is scheduled for ratification in Q3 2003 2 WPA will be available Q3 2003 as a driver or firmware download 3 Available soon as a firmware and driver update
8 Wireless Basics (continued) Installation Considerations The D-Link Air Xpert T DWL-AG650 let
s 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:
1. Keep the number of walls and ceilings between the DWL-AG650 and
other network devices to a minimum - each wall or ceiling can reduce your D-Link wireless productâ€™s range from 3-90 feet (1-30 meters.) Position your devices so that the number of walls or ceilings is minimized.
2. 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.
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 may generate extreme RF noise.
9 Getting Started
There are basically two modes of networking:
! Infrastructure â€“ using an Access Point, or Wireless Router, such as the DWL-7000AP.
! Ad-Hoc â€“ directly connecting to another computer, for peer-to-
peer communication, using wireless network adapters on each computer, such as two or more DWL-AG650 wireless network 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 AirXpert DI-774
A laptop computer with a wireless adapter - D-Link AirXpert DWL-AG650
A desktop computer with a wireless adapter - D-Link AirXpert DWL-AG520, D-Link AirPlus Xtreme G DWL- G520, D-Link AirPro DWL-AB520,or D-Link AirPlus DWL-520+
