Introduction
Connect to wireless networks at farther distances than before with D-Link AirPlus Xtreme G™ line of products infused with Double XR (2XR) Technology. By combining
D-Link’s new 2XR technology with D-Link 108G technology, this new Wireless Desktop Adapter offers dramatic performance improvements over standard 802.11g.
Based on the latest in Smart Antenna technology, 2XR technology provides the DWL-G520M Wireless 108G MIMO Desktop Adapter with the performance boost which delivers Xccelerated Rates at Xtended Range than standard 802.11g. When paired with D-Link’s 2XR-powered Wireless 108G MIMO Router for an end-to-end solution, reach up to 8x faster speeds at 8x farther coverage. Have more flexibility in the placement of your desktop and still maintain a strong wireless connection.
Even if only your client adapter is 2XR-enabled, you can still experience the performance benefits of faster rates at father distances with virtually any standard
802.11g wireless router. In addition, the DWL-G520M remains backward compatible to 802.11b. As an end-to-end 2XR solution, or even as a single-ended solution, D-Link’s 2XR technology is capable of providing exceptional wireless performance while dramatically reducing the number of dead spots throughout your home or office.
Introduction
With an included configuration utility and the Installation Wizard, setup for your DWL-G520M is a straightforward process. The utility keeps track of your most frequently accessed networks and their specific settings, so joining networks is an automatic process. The DWL-G520M also supports the latest security features such as WPA-PSK making your adapter compatible with secure wireless networks.
* 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 throughput rate.

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 to 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.
Wireless Basics
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.
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-G520M Wireless PCI Adapter utilizes the 802.11g standard.
The IEEE 802.11g standard is an extension of the 802.11b standard. It increases the data rate up to 54Mbps 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 high­speed 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-G520M 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 section of this manual.
Wireless Basics
The DWL-G520M 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 up to 11Mbps in the 2.4GHz range. Also based on the IEEE 802.11b standard, the DWL-G520M is interoperable with existing compatible
2.4GHz wireless technology with data transfer speeds of up to 11Mbps.

Installation Considerations
The DWL-G520M 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 the number of walls and ceilings between the DWL-G520M and other network devices to a minimum - each wall or ceiling can reduce your DWL-G520M’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.
Installation Considerations
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.
Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices
or appliances that generate RF noise.

Getting Started
There are basically two modes of networking:
Infrastructure – using an access point or router, such as the DI-624M.
Ad-Hoc – directly connecting to another computer, for Peer-to-Peer communication,
using wireless network adapters on each computer, such as two or more DWL-G520M Wireless Network adapters.
Getting Started
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 108G MIMO DI-634M
Desktop computers with a D-Link 108G MIMO DWL-G520M
A cable modem -
D-Link DCM-202
