4IntroductionThe D-Link AirPlus Xtreme G DWL-G520 Wireless PCI Adapter is a 802.11g high-performance, wireless adapter that supports high-speed wireless networking at home,at work or in public places.Unlike most network cards, the DWL-G520 provides data transfers at up to 54 Mbps(compared to the standard 11 Mbps) when used with other D-Link AirPlus Xtreme Gproducts. The 802.11g standard is backwards compatible with 802.11b products.Thismeans that you do not need to change your entire network to maintain connectivity. Youmay sacrifice some of 802.11g’s speed when you mix 802.11b and 802.11g devices, butyou will not lose the ability to communicate when you incorporate the 802.11g standardinto your 802.11b network. You may choose to slowly change your network by graduallyreplacing the 802.11b devices with 802.11g devices .In addition to offering faster data transfer speeds when used with other 802.11g products,the DWL-G520 has the newest, strongest, most advanced security features availabletoday. When used with other 802.11g WPA (WiFi Protected Access) and 802.1xcompatible products in a network with a RADIUS server, the security features include:WPA*: A new security feature, Wi-Fi Protected Access authorizes and identifies usersbased on a secret key that changes automatically at a regular interval.WPA uses TKIP (Temporal Key Integrity Protocol) to change the temporalkey every 10,000 packets (a packet is a kind of message transmitted over anetwork.) This insures much greater security than the standard WEP security.(By contrast, the older WEP encryption required the keys to be changedmanually.)802.1x: Authentication is a first line of defense against intrusion. In the Authenticationprocess the server verifies the identity of the client attempting to connect to thenetwork. Unfamiliar clients would be denied access.For home users that will not incorporate a RADIUS server in their network, the securityfor the DWL-G520, used in conjunction with other 802.11g products, will still be muchstronger than ever before. Utilizing the Pre Shared Key mode of WPA, the DWL-G520will obtain a new security key every time it connects to the 802.11g network. You onlyneed to input your encryption information once in the configuration menu. No longer willyou have to manually input a new WEP key frequently to ensure security, with theDWL-G520, you will automatically receive a new key every time you connect, vastlyincreasing the safety of your communications.*WPA will be available Spring 2003 as a free downloadTM

6D-Link wireless products are based on industry standards to provide easy-to-use and compatible high-speed wireless connectivity within your home, businessor public access wireless networks. D-Link wireless products will allow youaccess to the data you want, when and where you want it. You will be able toenjoy the freedom that wireless networking brings.A WLAN is a cellular computer network that transmits and receives data withradio signals instead of wires. WLANs are used increasingly in both home andoffice environments, and public areas such as airports, coffee shops anduniversities. Innovative ways to utilize WLAN technology are helping people towork and communicate more efficiently. Increased mobility and the absence ofcabling and other fixed infrastructure have proven to be beneficial for manyusers.Wireless BasicsWireless users can use the same applications they use on a wired network.Wireless adapter cards used on laptop and desktop systems support the sameprotocols as Ethernet adapter cards.
7Wireless Basics (continued)People use WLAN technology for many different purposes:Mobility - Productivity increases when people have access to data in anylocation within the operating range of the WLAN. Management decisions basedon real-time information can significantly improve worker efficiency.Low Implementation Costs – WLANs are easy to set up, manage, changeand relocate. Networks that frequently change can benefit from WLANs easeof implementation. WLANs can operate in locations where installation of wiringmay be impractical.Installation and Network Expansion - Installing a WLAN system can befast 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 - evenoutside the home or office.Inexpensive Solution – Wireless network devices are as competitively pricedas conventional Ethernet network devices.Scalability – WLANs can be configured in a variety of ways to meet the needsof specific applications and installations. Configurations are easily changedand range from peer-to-peer networks suitable for a small number of users tolarger infrastructure networks to accommodate hundreds or thousands ofusers, depending on the number of wireless devices deployed.D-Link AirPlus DI-614+Enhanced 2.4GHz Wireless RouterD-Link AirPlus DWL-650+, D-Link AirPlus Xtreme G DWL-G650Wireless Cardbus Adapters used with laptop computersD-Link AirPlus DWL-520+, D-Link AirPlus Xtreme G DWL-G520Wireless PCI cards used with desktop computersD-Link AirPlus DWL-900AP+and D-Link AirPlusXtreme G DWL-2000APWireless Access PointsD-Link AirPlusXtreme G DI-624High-Speed 2.4GHz Wireless RouterThe DWL-G520 is compatible with the following wireless products:
8Standards-Based TechnologyThe DWL-G520 Wireless PCI Adapter utilizes the 802.11g standard.The IEEE 802.11g standard is an extension of the 802.11b standard. It increasesthe data rate up to 54 Mbps 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 MPEGformat over your network without noticeable delays. This technology works bytransmitting high-speed digital data over a radio wave utilizing OFDM (OrthogonalFrequency Division Multiplexing) technology. OFDM works by splitting the radiosignal into multiple smaller sub-signals that are then transmitted simultaneouslyat different frequencies to the receiver. OFDM reduces the amount of crosstalk(interference) in signal transmissions. The D-Link DWL-G520 will automaticallysense the best possible connection speed to ensure the greatest speed andrange possible.802.11g offers the most advanced network security features available today,including: WPA , 802.1x, TKIP, AES and Pre-Shared Key mode. These securityfeatures are explained in more detail in the Introduction and the Features sectionof this manual.The DWL-G520 is backwards compatible with 802.11b devices. This meansthat if you have an existing 802.11b network, the devices in that network will becompatible with 802.11g devices at speeds up to 11Mbps in the 2.4GHz range.Wireless Basics (continued)11WPA will be available Spring 2003 as a free download
9Wireless Basics (continued)Installation ConsiderationsThe D-Link AirPlus Xtreme G DWL-G520 lets you access your network, usinga wireless connection, from virtually anywhere within its operating range. Keepin mind, however, that the number, thickness and location of walls, ceilings, orother 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 maximizingwireless range is to follow these basic guidelines:1. Keep the number of walls and ceilings between the DWL-G520 and other network devices to a minimum - each wall or ceiling can reduce your D-Link AirPlus Extreme G Wireless product’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 (e.g., wireless telephone; electric shaver; microwave oven; hair dryer etc.)
