7Wireless Basics (continued)more efficiently. Increased mobility and the absence of cabling and otherfixed infrastructure have proven to be beneficial for many users.Wireless users can use the same applications they use on a wired network.Wireless adapter cards used on laptop and desktop systems support thesame protocols as Ethernet adapter cards.Under many circumstances, it may be desirable for mobile network devicesto link to a conventional Ethernet LAN in order to use servers, printers or anInternet connection supplied through the wired LAN. A Wireless Router is adevice used to provide this link.People use wireless LAN 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 (Wireless Local Area Networks)are easy to set up, manage, change and relocate. Networks that frequentlychange, both physically and logically, can benefit from WLANs ease ofimplementation. WLANs can operate in locations where installation of wiringmay be impractical.Installation Speed and Simplicity - Installing a wireless LAN systemcan be fast and easy and can eliminate the need to pull cable through wallsand ceilings.Network Expansion - Wireless technology allows the network to go wherewires cannot go.Scalability – Wireless Local Area Networks (WLANs) can be configured ina variety of topologies to meet the needs of specific applications andinstallations. Configurations are easily changed and range from peer-to-peernetworks suitable for a small number of users to larger infrastructurenetworks to accommodate hundreds or thousands of users, depending onthe number of wireless devices deployed.to utilize WLAN technology are helping people to work and communicate
8Wireless Basics (continued)The DI-754 is compatible with other D-Link AirPro 802.11a products, whichinclude:♦5GHz Wireless Cardbus Adapters used with laptop computers(DWL-A650)♦5GHz Wireless PCI Adapters used with desktop computers(DWL-A520)The DI-754 is also compatible with the D-Link AirPlus 802.11b wireless family(when you install the DWL-650+ into the expansion slot), which includes:♦Enhanced 2.4GHz Wireless Cardbus Adapters used with laptopcomputers (DWL-650+)♦Enhanced 2.4GHz Wireless PCI cards used with desktop computers(DWL-520+)Standards-Based TechnologyThe versatile DI-754 Wireless Broadband Router integrates both 802.11a andoptional (with D-Link DWL-650+) 802.11b standards into a single unit.The IEEE 802.11a standard designates that devices may operate at an optimaldata rate of 54 Mbps (72 Mbps in proprietary Turbo mode.) This means that inmost environments, within the specified range of this device, you will be able totransfer large files quickly or even watch a movie in MPEG format over yournetwork without noticeable delays. This technology works by transmitting high-speed digital data over a radio wave utilizing OFDM (Orthogonal FrequencyDivision Multiplexing) technology. OFDM works by splitting the radio signalinto multiple smaller sub-signals that are then transmitted simultaneously atdifferent frequencies to the receiver. OFDM reduces the amount of crosstalk(interference) in signal transmissions. D-Link AirPro 802.11a products willautomatically sense the best possible connection speed to ensure the greatestspeed and range possible.Based on the IEEE 802.11b standard (when the optional D-Link DWL-650+ isinstalled in the expansion slot), the DI-754 is also interoperable with existingcompatible 2.4GHz wireless technology with data transfer speeds of up to22Mbps (with the D-Link AirPlus family of wireless devices), as well as standard802.11b technology (the D-Link Air family of wireless devices), with speeds ofup to 11Mbps.
9Wireless Basics (continued)Installation ConsiderationsThe D-Link AirPro DI-754 lets you access your network, using a wirelessconnection, from virtually anywhere. Keep in mind, however, that thenumber, thickness and location of walls, ceilings, or other objects that thewireless signals must pass through, may limit the range. Typical ranges varydepending on the types of materials and background RF (radio frequency)noise in your home or business. The key to maximizing wireless range is tofollow these basic guidelines:1. Keep the number of walls and ceilings between the DI-754 and your receiving device (e.g., the DWL-A650 or the DWL-650+) to a minimum - each wall or ceiling can reduce your D-Link AirPro 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! Try to make sure that devices are positioned so that the signal will travel straight through a wall or ceiling for better reception.3. Building Materials make a difference - 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.
