4IntroductionThe DWL-7200AP has the newest, strongest and most advanced security featuresavailable today. When used with other 802.11 WPA (Wi-Fi Protected Access) compatibleproducts in a network with a RADIUS server, the security features include:WPA: Wi-Fi Protected Access which authorizes and identifies users based on a secretkey that changes automatically at regular intervals. WPA uses TKIP (TemporalKey Integrity Protocol) to change the temporal key every 10,000 packets (apacket is a kind of message transmitted over a network.) This ensures muchgreater security than the standard WEP security. (By contrast, the previousWEP encryption implementations required the keys to be changed manually.)For home users that will not incorporate a RADIUS server in their network, the securityfor the DWL-7200AP, used in conjunction with other WPA-compatible 802.11 products,will still be much stronger than ever before. Utilizing the Pre-Shared Key mode ofWPA, the DWL-7200AP will obtain a new security key every time it connects to the802.11 network. You only need to input your encryption information once in theconfiguration menu. No longer will you have to manually input a new WEP key frequentlyto ensure security. With the DWL-7200AP, you will automatically receive a new keyevery time you connect, vastly increasing the safety of your communication.At up to fifteen times the speed of previous wireless devices (up to 108Mbps in SuperAG mode), you can work faster and more efficiently, increasing productivity. With theDWL-7200AP, bandwidth-intensive applications like graphics or multimedia will benefitsignificantly because large files are able to move across the network quickly.Inclusion of all three standards (802.11g; 802.11a; 802.11b) means that the DWL-7200APis versatile enough to allow connection to almost any 802.11 network or device.
5Better security with WPA- The DWL-7200AP can securely connect to wire-less clients on the network using WPA (Wi-Fi Protected Access) providing amuch higher level of security for your data and communications than has previ-ously been available.Compatible with the 802.11b standard to provide a wireless data rate of up to11Mbps with 802.11b devices.FeaturesFaster Wireless Networking with speeds up to 108Mbps in Super AG modeCompatible with 802.11a, 802.11b and 802.11g Devices - Fully compatiblewith the IEEE 802.11a, 802.11b and 802.11g standards, the DWL-7200AP canconnect with existing 802.11b-, 802.11g- or 802.11a- compliant wireless networkadapter cards.LEDsLED stands for Light-Emitting Diode.

6Wireless BasicsD-Link AirPremierTM AG wireless products are based on industry standards to provideeasy-to-use and compatible high-speed wireless connectivity within your home, businessor public access wireless networks. Strictly adhering to the IEEE standard, the D-LinkAirPremierTM AG wireless family of products will allow you to securely access the datayou want, when and where you want it. You will be able to enjoy the freedom thatwireless networking delivers.A wireless local area network (WLAN) is a cellular computer network that transmits andreceives data with radio signals instead of wires. Wireless LANs are used increasinglyin both home and office environments, and public areas such as airports, coffee shopsand universities. Innovative ways to utilize WLAN technology are helping people to workand communicate more efficiently. Increased mobility and the absence of cabling andother fixed infrastructure have proven to be beneficial for many users.Wireless users can use the same applications they use on a wired network. Wirelessadapter cards used on laptop and desktop systems support the same protocols asEthernet adapter cards.People use wireless LAN technology for many different purposes:Mobility - Productivity increases when people have access to data in any locationwithin the operating range of the WLAN. Management decisions based on real-timeinformation 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. WLANscan operate in locations where installation of wiring may be impractical.Installation and Network Expansion - Installing a WLAN system can be fast andeasy and can eliminate the need to pull cable through walls and ceilings. Wirelesstechnology allows the network to go where wires cannot go - even outside the home oroffice.Inexpensive Solution - Wireless network devices are as competitively priced asconventional Ethernet network devices.Scalability - WLANs can be configured in a variety of ways to meet the needs ofspecific applications and installations. Configurations are easily changed and rangefrom Peer-to-Peer networks suitable for a small number of users to larger infrastructurenetworks to accommodate hundreds or thousands of users, depending on the number ofwireless devices deployed.
7Wireless Basics (continued)Standards-Based TechnologyThe DWL-7200AP Wireless Access Point utilizes the 802.11a, 802.11b and draft 802.11gstandard.The IEEE 802.11g standard is an extension of the 802.11b standard. It increases thedata rate up to 54Mbps (108Mbps in Super G mode) within the 2.4GHz band. The802.11a standard also increases the data rate up to 54Mbps, 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 willbe able to transfer large files quickly or even watch a movie in MPEG format over yournetwork without noticeable delays. This technology works by transmitting high-speeddigital data over a radio wave utilizing OFDM (Orthogonal Frequency Division Multiplexing)technology. OFDM works by splitting the radio signal into multiple smaller sub-signalsthat are then transmitted simultaneously at different frequencies to the receiver. OFDMreduces the amount of crosstalk (interference) in signal transmissions.The DWL-7200AP offers the most advanced network security features available today,including WPA.In addition to its compatibility with 802.11g and 802.11a devices, the DWL-7200AP iscompatible with 802.11b devices. This means that if you have an existing 802.11b network,or a network with a mixture of 802.11g, 802.11a and 802.11b, the devices in that networkwill be compatible with the DWL-7200AP.
8Wireless Basics (continued)Installation ConsiderationsDesktop and laptop computers with wireless network adapters installed can access theD-Link AirPremierTM AG DWL-7200AP from virtually anywhere within its operating range.Keep in mind, however, that the number, thickness and location of walls, ceilings, orother objects that the wireless signals must pass through, may limit the range. Typicalranges 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 thesebasic guidelines:Be aware of the direct line between network devices. A wall that is 1.5feet 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 awall or ceiling (instead of at an angle) for better reception.Building materials can impede the wireless signal - a solid metal door oraluminum studs may have a negative effect on range. Try to positionwireless devices and computers with wireless adapters so that the signalpasses through drywall or open doorways and not other materials.Keep your product away (at least 3-6 feet or 1-2 meters) fromelectrical devices or appliances that may generate extreme RF noise.Keep the number of walls and ceilings between the DWL-7200AP andother network devices to a minimum - each wall or ceiling can reduceyour D-Link wireless product’s range from 3-90 feet (1-30 meters.) Positionyour devices so that the number of walls or ceilings is minimized.1234
