4IntroductionAt up to five times the speed of previous wireless devices, you can work faster and moreefficiently, increasing productivity. With the DI-774, bandwidth-intensive applications likegraphics or multimedia will benefit significantly because large files are able to moveacross the network quickly. This versatile wireless router also features four times thenumber of non-overlapping channels than a device that supports only 802.11g, so moreusers can access the network.Support for all three standards (802.11g; 802.11a; 802.11b) means that you can growyour network without having to worry about legacy wireless equipment being incompatiblewith newer compliant devices from other manufacturers. This also allows networkadministrators to partition the usage of the dualband by segmenting users and creatingspecial access privilege networks for classified document transfer and communications.With the DI-774 you can securely connect to wireless clients on the network using802.1x for wireless user authentication, as well as WPA (Wi-Fi Protected Access )providing you a much higher level of security for your data and communications thanhas previously been available.Through its easy-to-use Web-based user interface, the DI-774 lets you control theinformation that is accessible to those on the wireless network, whether from the Internetor from your company’s server:Content Filtering – Easily applied content filtering based on MAC Address, IP Address,URL and /or Domain Name.Filter Scheduling – Filters can be scheduled to be active on certain days or for aduration of hours or minutes.Network Address Translation – NAT protects the DI-774 and its users from outsideintruders gaining access to your private networkVPN Multiple/Concurrent Sessions – Supports multiple and concurrent IPSec andPPTP sessions, so multiple users behind the DI-774 can access corporate networksthrough various VPN clients more securely.

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-774 Wireless Broadband Router utilizes the new 802.11g standard, in additionto the 802.11a and 802.11b standards.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..Wireless Basics (continued)Installation ConsiderationsThe D-Link Air Xpert DI-774 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-624 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.11111Be 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.22222Building 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.33333Keep your product away (at least 3-6 feet or 1-2 meters) from electricaldevices or appliances that generate extreme RF noise.44444
