![4The versatile 802.11a/b/g compatible DWL-AG520 gives you an immediate way to expandto your existing 802.11b network and protect your overall wireless network investment.When you add an 802.11a/b/g access point (D-Link Air Xpert DWL-7000AP) or router (D-Link Air Xpert DI-774), your network will be capable of handling up to four times the userload of your current 802.11b network.IntroductionThe D-Link Air Xpert DWL-AG520 Tri-Mode Dualband Wireless PCI Adapter, wheninstalled into your desktop PC, provides you a versatile way to wirelessly connect to anyone of three available wireless networks - 802.11b and the newer, faster 802.11g and802.11a that operate in two discrete, non-interfering frequency bands, 2.4GHz and 5GHz.Along with compatibility to earlier 802.11b networks, the DWL-AG520 also offers therobust speed (up to 54Mbps) of the newer 802.11g and 802.11a standards, so thateveryone can work faster and more efficiently. Additionally, the 802.11a 5GHz bandoffers a way to quickly transfer data in a frequency range that does not experienceinterference or interruptions from cordless phones, microwave ovens and other devicesthat use the 2.4GHz frequency band.In addition to offering faster data transfer speeds when used with other 802.11a or 802.11g products, the DWL-AG520 has the newest, most advanced security featuresavailable today, using the draft 802.11i security standard. These additional securityfeatures are optional. You may choose to continue using the familiar WEP security, oryou may not wish to utilize security features at all. However, if you do choose to use theDWL-AG520’s powerful security features with other WPA (WiFi Protected Access) and802.1x compatible products in a network with a RADIUS server, the security featureswill 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 ensures 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.*WPA will be available Q3 2003 as a driver downloadTMUsers that choose not to incorporate a RADIUS server in their network may also use theoptional enhanced security features, or they may wish to continue using the standardWEP security, or they may choose to use no security at all. However, if you do wish toexperience the enhanced security of the DWL-AG520 in conjunction with other draft802.11i compatible products, without a RADIUS server, the Pre Shared Key mode ofWPA will assign a new security key every time the DWL-AG520 connects to the draft802.11i Access Point. If you choose to enable the enhanced security features of theDWL-AG520, you need only to input your encryption information once in the configurationmenu. No longer will you have to manually change the WEP key to ensure security -with the DWL-AG520, you will automatically receive a new key every time you connect,vastly increasing the safety of your communications.](https://usermanual.wiki/D-Link/2003070024-1.Manual-1-revised/User-Guide-364690-Page-4.png)

![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 the installation ofwiring may 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.The DWL-AG520 is compatible with the following wireless products:D-Link Air Xpert DWL-AG650, D-Link AirPro DWL-A650, D-LinkAirPlus DWL-650+, D-Link AirPlus Xtreme G DWL-G650,D-Link AirPro DWL-AB650Wireless Cardbus Adapters used with laptop computersD-Link AirPro DWL-A520 and D-Link AirPlus DWL-520+,D-Link AirPlus Xtreme G DWL-G520, another D-Link Air XpertDWL-AG520, and D-Link AirPro DWL-AB520Wireless PCI cards used with desktop computersD-Link AirPlus DWL-900AP+, D-Link AirPlus Xtreme G DWL-2000AP and D-Link Air Xpert DWL-7000APWireless Access Points!!!!D-Link AirPlus DI-614+, D-Link AirPlus Xtreme G DI-624 andD-Link Air Xpert DI-774Wireless Broadband Routers](https://usermanual.wiki/D-Link/2003070024-1.Manual-1-revised/User-Guide-364690-Page-7.png)
![8Standards-Based TechnologyThe DWL-AG520 Wireless Cardbus Adapter utilizes the 802.11a, 802.11b and802.11g standard.The IEEE 802.11g standard is an extension of the 802.11b standard. Itincreases the data rate up to 54 Mbps within the 2.4GHz band. The 802.11astandard 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 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-AG520 will automaticallysense the best possible connection speed to ensure the greatest speed andrange possible.The DWL-AG520 offers the most advanced network security features availabletoday, including: WPA and 802.1x.In addition to its compatibility with 802.11g and 802.11a devices, the DWL-AG520 is compatible with 802.11b devices. This means that if you have anexisting 802.11b network, or a network with a mixture of 802.11g, 802.11a and802.11b, the devices in that network will be compatible with the DWL-AG520.Wireless Basics (continued)WPA will be available Q3 2003 as a driver or firmware download21](https://usermanual.wiki/D-Link/2003070024-1.Manual-1-revised/User-Guide-364690-Page-8.png)
![9Wireless Basics (continued)Installation ConsiderationsThe D-Link Air Xpert DWL-AG520 lets you access your network, using awireless 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-AG520 and other network devices to a minimum - each wall or ceiling can reduce your D-Link 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.TM](https://usermanual.wiki/D-Link/2003070024-1.Manual-1-revised/User-Guide-364690-Page-9.png)
