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. Strictly adhering to the IEEE
standard, the D-Link wireless family of products will allow you to securely
access the data you want, when and where you want it. You will be able to
enjoy the freedom that wireless networking delivers.
A wireless local area network (WLAN) is a cellular computer network that
transmits and receives data with radio signals instead of wires. Wireless
LANs 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.
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 Router is a
device used to provide this link.
6 Wireless Basics (continued) People use wireless LAN 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 (Wireless Local Area Networks) are easy to set up, manage, change and relocate. Networks that frequently change,
both physically and logically, can benefit from WLANs ease of implementation.
WLANs can operate in locations where installation of wiring may be impractical. Installation Speed and Simplicity - Installing a wireless LAN system can be fast and easy and can eliminate the need to pull cable through walls and
ceilings. Network Expansion - Wireless technology allows the network to go where wires cannot. Scalability â€“ Wireless Local Area Networks (WLANs) can be configured in a variety of topologies to meet the needs of specific applications or existing
infrastructures. 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.
7 Wireless Basics (continued) The DWL-AB520 is compatible with other D-Link AirPro 802.11a products, which include:
â™¦ 5GHz Wireless Cardbus Adapters used with laptop computers
â™¦ 5GHz Multimode Wireless Broadband Routers computers (DI-764,
â™¦ 5GHz Wireless Access Points (DWL-5000AP, DWL-6000AP) The DWL-AB520 is also compatible with D-LinkAir and AirPlus 802.11b wireless products, which include:
â™¦ 2.4GHz Wireless Cardbus Adapters used with laptop computers
â™¦ 2.4GHz Wireless PCI cards used with desktop computers
â™¦ Enhanced 2.4GHz Wireless Access Point (DWL-900AP+) â™¦ Enhanced 2.4GHz Wireless Broadband Router (DI-614+) Standards-Based Technology
The versatile DWL-AB520 Wireless Multimode PCI Adapter integrates both 802.11a and 802.11b standards into a single unit.
The IEEE 802.11a standard designates that devices may operate at an optimal data rate of 54 Mbps (72 Mbps in proprietary Turbo mode.) 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. D-Link AirPro 802.11a products will automatically sense the best possible connection speed to ensure the greatest speed and range possible.
Based on the IEEE 802.11b standard, the DWL-AB520 is also interoperable with existing compatible 2.4GHz wireless technology with data transfer speeds of up to 11Mbps.
8 Wireless Basics (continued) Installation Considerations The D-Link AirPro DWL-AB520 lets you access your network, using a wireless connection, from virtually anywhere. 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-AB520 and
other network devices to a minimum - each wall or ceiling can reduce your D-Link AirPro Wireless productâ€™s range from 3-90 feet (1-30 meters.) Position your receiving 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! Try to make sure that devices are positioned so that the signal will travel straight through a wall or ceiling for better reception.
3. Building Materials make a difference - 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 generate RF noise.
9 Getting Started With its default settings, the DWL-AB520 will connect with other D-Link AirPro products, right out of the box.
There are basically two modes of networking: Infrastructure â€“ using an Access Point, such as the DWL-900AP+, DWL-5000AP or DWL-6000AP. 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-AB520 wireless network PCI 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 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 AirPro DI-764
A laptop computer with a wireless adapter - D-Link AirPro DWL-A650 or AirPlus DWL-650+
A desktop computer with a wireless adapter - D-Link AirPro DWL-AB520
A Cable modem - D-Link DCM-200

Connect the Cable or DSL modem to your broadband router (see the Quick Installation Guide included with your router.)
Install the D-Link AirPro DWL-AB520 wireless PCI adapter into an available
PCI slot on your desktop computer. (See the Quick Installation Guide included with the DWL-AB520.)
If you are connecting a laptop computer to your network, install the drivers for
the wireless cardbus adapter (e.g., D-Link AirPro DWL-A650, DWL-650+ or
the DWL-650) into a laptop computer. (See the Quick Installation Guide included with the DWL-A650, DWL-650+, or DWL-650.)
Getting Started Setting up a Wireless Ad Hoc Network DWL-A650 DWL-650+
Install the D-Link AirPro DWL-AB520 Wireless Network adapter into the desktop computer. See the Quick Installation Guide included with the product for installation instructions.
Install a wireless network adapter into the laptop computer. In the example above the DWL-A650, DWL-650+ or DWL-650 may be installed into a laptop computer. See the Quick Installation Guide included with the product.
Set the wireless configuration for the adapters to Ad-Hoc mode, set the adapters to the same channel, and assign an IP Address to each computer on the Ad-Hoc network. (See Box below) IP Address
When assigning IP Addresses to the computers on the network, please remember that the IP Address for each computer must be in the same IP Address range as all the computers in the network, and the subnet mask must be exactly the same for all the computers in the network.
For example: If the first computer is assigned an IP Address of 192.168.0.2 with a Subnet Mask of 255.255.255.0, then the second computer can be assigned an IP Address of 192.168.0.3 with a Subnet Mask of 255.255.255.0, etc. IMPORTANT: If computers or other devices are assigned the same IP Address, one or more of the devices may not be visible on the network.
