Introduction

At up to five times the speed of previous wireless devices, you can work faster and more efficiently , increasing productivity . With the DI-774, bandwidth-intensive applications like graphics or multimedia will benefit significantly because large files are able to move across the network quickly. This versatile wireless router also features four times the number of non-overlapping channels than a device that supports only 802.1 1g, so more users can access the network.

Support for all three standards (802.1 1g; 802.1 1a; 802.1 1b) means that you can grow your network without having to worry about legacy wireless equipment being incompatible with newer compliant devices from other manufacturers. This also allows network administrators to partition the usage of the dualband by segmenting users and creating special access privilege networks for classified document transfer and communications.

With the DI-774 you can securely connect to wireless clients on the network using

802.1x 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 than has previously been available.

Through its easy-to-use Web-based user interface, the DI-774 lets you control the information that is accessible to those on the wireless network, whether from the Internet or 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 a duration of hours or minutes.

Network Address Translation – NAT protects the DI-774 and its users from outside intruders gaining access to your private network

VPN Multiple/Concurrent Sessions – Supports multiple and concurrent IPSec and PPTP sessions, so multiple users behind the DI-774 can access corporate networks through various VPN clients more securely .

WP A (Wi Fi Protected Access ) authorizes and identifies users based on a

secret key that changes automatically at a regular interval, for example:

TKIP (Temporal Key Integrity Protocol), in conjunction with a RADIUS

server, changes the temporal key every 10,000 packet s, ensuring greater security

Pre-Shared Key mode means that the home user, without a RADIUS

server, will obt ain a new security key every time the he or she connects to the network, vastly improving the safety of communications on the network.

802.1x Authentication in conjunction with the RADIUS server verifies the

identity of would be clients

Wireless Basics

D-Link wireless products are based on industry standards to provide easy-to-use and compatible high-speed wireless connectivity within your home, business or public access wireless networks. D-Link wireless products will allow you access to the data you want, when and where you want it. Y ou will be able to enjoy the freedom that wireless networking brings.

A WLAN is a cellular computer network that transmits and receives data with radio signals instead of wires. WLANs are used increasingly in both home and office environments, and public areas such as airports, coffee shops and universities. Innovative ways to utilize WLAN technology are helping people to work and communicate more efficiently . Increased mobility and the absence of cabling and other fixed 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 the same protocols as Ethernet adapter cards.

People use wireless LAN technology for many different purposes:

Mobility - Productivity increases when people have access to data in any location

within the operating range of the WLAN. Management decisions based 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 can benefit from WLANs ease of implementation. WLANs can operate in locations where installation of wiring may be impractical.

Installation and Network Expansion - Installing a WLAN system can be fast

and easy and can eliminate the need to pull cable through walls and ceilings. Wireless technology allows the network to go where wires cannot go - even outside the home or office.

Scalability – WLANs can be configured in a variety of topologies to meet the needs of

specific applications and installations. Configurations are easily changed and range from peer-to-peer networks suitable for a small number of users to larger infrastructure networks to accommodate hundreds or thousands of users, depending on the number

of wireless devices deployed.

Inexpensive Solution - Wireless network devices are as competitively priced as

conventional Ethernet network devices.

Wireless Basics (continued)

Standards-Based Technology

The DI-774 Wireless Broadband Router utilizes the new 802.11g standard, in addition to the 802.1 1a and 802.1 1b standards.

The IEEE 802.11g st andard is an extension of the 802.11b standard. It increases the 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 MPEG format over your network without noticeable delays. This technology works by transmitting high-speed digital data over a radio wave utilizing OFDM (Orthogonal Frequency Division Multiplexing) technology. OFDM works by splitting the radio signal into multiple smaller sub-signals that are then transmitted simultaneously at different frequencies to the receiver . OFDM reduces the amount of crosstalk (interference) in signal transmissions.

Installation Considerations

The 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 must pass through, may limit the range. T ypical ranges 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 these basic guidelines:

Keep the number of walls and ceilings between the DI-624 and other network

devices 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 devices so that the number of walls or ceilings is minimized.

Be aware of the direct line between network devices. 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.

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.

Keep your product away (at least 3-6 feet or 1-2 meters) from electrical

devices or appliances that generate extreme RF noise.
