4IntroductionThe D-Link AirPlus G DI-524 802.11g/2.4 Ghz Wireless Router is an 802.11g high-performance, wireless router that supports high-speed wireless networking at home, atwork or in public places.Unlike most routers, the DI-524 provides data transfers at up to 54 Mbps (compared tothe standard 11 Mbps) when used with other D-Link AirPlus G products. The 802.11gstandard is backwards compatible with 802.11b products. This means that you do notneed to change your entire network to maintain connectivity. You may sacrifice some of802.11g’s speed when you mix 802.11b and 802.11g devices, but you will not lose theability to communicate when you incorporate the 802.11g standard into your 802.11bnetwork. You may choose to slowly change your network by gradually replacing the802.11b devices with 802.11g devices .In addition to offering faster data transfer speeds when used with other 802.11g products,the DI-524 has the newest, strongest, most advanced security features available today.When used with other 802.11g WPA (WiFi Protected Access) and 802.1x compatibleproducts in a network with a RADIUS server, the security features include:WPA: Wi-Fi Protected Access authorizes and identifies users based on a secret keythat changes automatically at a regular interval. 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 insures muchgreater security than the standard WEP security. (By contrast, the older WEPencryption required the keys to be changed manually.)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 DI-524, used in conjunction with other 802.11g products, will still be much strongerthan ever before. Utilizing the Pre Shared Key mode of WPA, the DI-524 will obtain anew security key every time it connects to the 802.11g network. You only need to inputyour encryption information once in the configuration menu. No longer will you have tomanually input a new WEP key frequently to ensure security, with the DI-524, you willautomatically receive a new key every time you connect, vastly increasing the safety ofyour communications.

8Wireless BasicsD-Link wireless products are based on industry standards to provide easy-to-use andcompatible high-speed wireless connectivity within your home, business or public accesswireless 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 networkingbrings.A WLAN is a cellular computer network that transmits and receives data with radiosignals instead of wires. WLANs are used increasingly in both home and officeenvironments, and public areas such as airports, coffee shops and universities. Innovativeways to utilize WLAN technology are helping people to work and communicate moreefficiently. Increased mobility and the absence of cabling and other fixed infrastructurehave 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 andrelocate. Networks that frequently change can benefit from WLANs ease ofimplementation. WLANs can operate in locations where installation of wiring may beimpractical.Installation and Network Expansion - Installing a WLAN system can be fastand easy 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.Scalability – WLANs can be configured in a variety of topologies 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 numberof wireless devices deployed.Inexpensive Solution - Wireless network devices are as competitively priced asconventional Ethernet network devices.
9Standards-Based TechnologyThe DI-524 Wireless Broadband Router utilizes the new 802.11g standard.The IEEE 802.11g standard is an extension of the 802.11b standard. It increases thedata 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 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 DI-524 is backwards compatible with 802.11b devices. This means that if you havean existing 802.11b network, the devices in that network will be compatible with 802.11gdevices at speeds of up to 11Mbps in the 2.4GHz range.Wireless Basics (continued)
10Wireless Basics (continued)Installation ConsiderationsThe D-Link AirPlus G DI-524 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 mustpass through, may limit the range. Typical ranges vary depending on the types of materialsand background RF (radio frequency) noise in your home or business. The key tomaximizing wireless range is to follow these basic guidelines:Keep the number of walls and ceilings between the DI-524 and other networkdevices to a minimum - each wall or ceiling can reduce your D-Link wirelessproduct’s range from 3-90 feet (1-30 meters). Position your devices so thatthe number of walls or ceilings is minimized.Be aware of the direct line between network devices. A wall that is 1.5 feetthick (.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! Positiondevices so that the signal will travel straight through a wall or ceiling (insteadof at an angle) for better reception.Keep your product away (at least 3-6 feet or 1-2 meters) from electricaldevices or appliances that generate extreme RF noise.Building Materials can impede the wireless signal - a solid metal door oraluminum studs may have a negative effect on range. Try to position wirelessdevices and computers with wireless adapters so that the signal passesthrough drywall or open doorways and not other materials.11111222223333344444
