4IntroductionThe D-Link AirPlusXtreme G DWL-2000AP High-Speed Wireless Access Point is adraft 802.11g high-performance, wireless access point that supports high-speed wirelessnetworking at home, at work or in public places.The DWL-2000AP is capable of operating in one of 4 different modes to meet yourwireless networking needs. The DWL-2000AP can operate as an Access Point; in AccessPoint-to-Access Point Bridging mode; Access Point-to-Multipoint Bridging mode; orWireless Client mode.The DWL-2000AP is an ideal solution for quickly creating and extending a wireless localarea network (WLAN) in offices or other workplaces, trade shows and special events.* Available Spring 2003 as a free downloadUnlike most access points, the DWL-2000AP provides data transfers at up to 54 Mbps(compared to the standard 11 Mbps) when used with other D-Link AirPlusXtremeGproducts. 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 .Authentication is a first line of defense against intrusion. In theAuthentication process the server verifies the identity of the client attemptingto connect to the network.Unfamiliar clients would be denied access.In addition to offering faster data transfer speeds when used with other 802.11g products,the DWL-2000AP 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:*802.1x*:A new security feature, Wi-Fi Protected Access authorizes and identifiesusers based on a secret key that changes automatically at a regularinterval. WPA uses TKIP (Temporal Key Integrity Protocol) to changethe temporal key every 10,000 packets (a packet is a kind of messagetransmitted over a network.) This insures much greater security than thestandard WEP security. (By contrast, the older WEP encryption requiredthe keys to be changed manually.)TM
5ConnectionsThe LAN Port isAuto-MDI/MDIX. Youcan insert either aStraight-through ora Cross-overEthernet cable inthis port in order toconnect the DWL-2000AP to a switchon the localnetwork.Receptorfor thePowerAdapterPressing theReset Buttonrestores therouter to itsoriginal factorydefault settings.

8D-Link wireless products are based on industry standards to provide easy-to-use and compatible high-speed wireless connectivity within your home, businessor wherever a wireless network is available. D-Link wireless products will allowyou access to the data you want, when and where you want it. You will be ableto enjoy the freedom that wireless networking brings.A wireless local area network (WLAN) is a cellular computer network thattransmits and receives data with radio signals instead of wires. WLANs areused increasingly in both home and office environments, and public areas suchas airports, coffee shops and universities. Innovative ways to utilize WLANtechnology are helping people to work and communicate more efficiently.Increased mobility and the absence of cabling and other fixed infrastructurehave proven to be beneficial for many users.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.Under many circumstances, it may be desirable for mobile network devices tolink to a conventional Ethernet LAN in order to use servers, printers or an Internetconnection supplied through the wired LAN. A Wireless Access Point is a devicethat can be used to provide this link.
9Wireless 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 decisionsbased 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, both physically andlogically, can benefit from a WLAN’s ease of implementation. WLANs canoperate in locations where installation of wiring 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 andceilings. Wireless technology allows the network to go where wires cannotgo-even outside the home or office.Scalability – WLANs can be configured in a variety of ways to meet theneeds of specific applications and installations. Configurations are easilychanged and range from peer-to-peer networks suitable for a small numberof users to larger infrastructure networks to accommodate hundreds orthousands of users, depending on the number of wireless devices deployed.Inexpensive solution– Wireless network devices are as competitivelypriced as conventional Ethernet network devices.The DWL-2000AP is compatible with the following wireless products:D-Link AirPlus DWL-650+,D-Link AirPlus XtremeG DWL-G650Wireless Cardbus Adapters used with laptop computersD-Link AirPlus DWL-520+, D-Link AirPlus XtremeG DWL-G520Wireless PCI cards used with desktop computers!!
10Standards-Based TechnologyThe DWL-2000AP Wireless Access Point utilizes the new 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-2000AP willautomatically sense the best possible connection speed to ensure the greatestspeed 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 securityfeatures are explained in more detail in the Introduction and the Features sectionof this manual.The DWL-2000AP 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 of up to 11Mbps in the 2.4GHzrange.Wireless Basics (continued)WPA will be available Spring 2003 as a free download1212802.11g standard is scheduled for ratification by IEEE Summer 2003802.1x will be available Spring 2003 as a free download33
11Wireless Basics (continued)Installation ConsiderationsThe D-Link AirPlus Xtreme G DWL-2000AP 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 therange. Typical ranges vary depending on the types of materials and backgroundRF (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-2000AP and your receiving device (e.g., the DWL-G650 or the DWL-650+) 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 receiving devices so that the number of walls or ceilings is minimized.2. Be aware of the direct line between routers and computers. 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 generate RF noise.
