D-Link, the industry pioneer in wireless networking, introduces another breakthrough in wireless connectivity â€” the D-Link AirXpert DWL-7000AP Wireless Access Point. This tri-mode, dualband Access Point provides the most expanded user bandwidth available in an AP. Wireless clients can connect to this AP using any one of its 11 non-overlapping channels to transfer data at speeds never before achievable in a wireless device. The DWL-7000AP operates seamlessly and simultaneously in both the 2.4GHz and 5GHz frequency spectrums supporting the 802.11b and the newer, faster 802.11a and 802.11g wireless standards. For offices, schools or public hotspots that already use 802.11b devices, the DWL-7000AP is a great way to expand an existing network and enable even more users to communicate with one another, access data and the Internet. Now, you can have an AP that will compliment your existing network and protect the investment you made when you provided the convenience of wireless networking.
The DWL-7000AP offers transfer rates up to 54Mbps in either the 2.4GHz or 5GHz bands, large data packets travel from the router to a remote desktop or roaming laptop PC at up to five times the speed of previous wireless devices. Everyone can work faster and more efficiently or watch a streaming video smoothly. The additional (802.11a) 5GHz band also offers a way to quickly transfer data without the interference produced by other devices operating in the 2.4GHz frequency. Network administrators can partition the usage of the dualband DWL-7000AP by segmenting the users on the wireless network by frequency band. Users who require special networking privileges â€” access to sensitive information, specific departments or videoconferencing â€” may use just the 802.11a channels; while other employees may just use the 802.11b and 802.11g channels. This type of user segmentation optimizes the AP s performance and delivers the best network experience to each set of users.
The DWL-7000AP is ideal for network administrators who require additional management, firewall, and other network security features. All of the AP s settings are easily accessible in the operating system independent, Web-based software user interface that also features a step-by-step Setup Wizard to get your router up and running in just a matter of minutes. The DWL-7000AP incorporates the 802.1x standard for wireless user authentication and WPA* (Wi-Fi Protected Access) which dynamically encrypts data as itâ€™s being sent.
*WPA features available as a firmware upgrade download in Q3 2003.

6 Wireless Basics D-Link Air Xpertwireless 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. Strictly adhering to the IEEE standard, the D-Link Air Xpert wireless family of products will allow you to securely access the data you want, when and where you want it. You will be able to enjoy the freedom that wireless networking delivers.
A wireless local area network (WLAN) is a cellular computer network that transmits and receives data with radio signals instead of wires. Wireless LANs 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.
Under many circumstances, it may be desirable for mobile network devices to link to a conventional Ethernet LAN in order to use servers, printers or an Internet connection supplied through the wired LAN. A Wireless Access Point (AP) is a device used to provide this link.
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 â€“ 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. Inexpensive Solution â€“ Wireless network devices are as competitively priced as conventional Ethernet network devices. Scalability â€“ WLANs can be configured in a variety of ways 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.
7 Wireless Basics (continued) The DWL-7000AP is compatible with the following wireless products:
" D-LinkAirPro DWL-A650, D-Link AirPlus DWL-650+, D-Link AirXpert DWL-A650, D-Link AirPlus Xtreme G DWL-G650 TM , D-Link AirPro DWL-AB650 Wireless Cardbus Adapters used with laptop computers
" D-LinkAirPro DWL-A520 and D-Link AirPlus DWL-520+, D-Link AirPlus Xtreme G DWL-G520, D-Link AirXpert DWL-AG520, and D-Link AirPro DWL-AB520 Wireless PCI cards used with desktop computers Standards-Based Technology
The DWL-7000AP Wireless Access Point utilizes the 802.11a, 802.11b anddraft 802.11g standard.
The IEEE 802.11g standard is an extension of the 802.11b standard. It increases the data rate up to 54 Mbps within the 2.4GHz band. The 802.11a standard also increases the data rate up to 54 Mbps, 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 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.
The DWL-7000AP offers the most advanced network security features available today, including: WPA and 802.1x.
In addition to its compatibility with 802.11g and 802.11a devices, the DWL-7000AP is compatible 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 network will be compatible with the DWL-7000AP.
8 Wireless Basics (continued) Installation Considerations
Desktop and laptop computers with wireless network adapters installed can access the D-Link Air Xpert DWL-7000AP 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. Typical 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 DWL-7000AP and
other network devices to a minimum - each wall or ceiling can reduce your D-Link wireless productâ€™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 may generate extreme RF noise.
9 Getting Started Right out of the box, with its default settings, the DWL-7000AP will automati- cally connect with other D-Link Air Xpert products IP ADDRESS Note: If you are using a DHCP-capable router in your network setup, such as the DI-604, you will not need to assign a static IP Address.
If you need to assign IP Addresses to the computers on the network, please remember that the IP Address for each computer must be in the same IP Address range as all the computers in the network, and the Subnet mask must be exactly the same for all the computers in the network.
For example: If the first computer is assigned an IP Address of 192.168.0.2 with a Subnet Mask of 255.255.255.0, then the second computer can be assigned an IP Address of 192.168.0.3 with a Subnet Mask of 255.255.255.0, etc. IMPORTANT: If computers or other devices are assigned the same IP Address, one or more of the devices may not be visible on the network.

Check that the IP Address assigned to the wireless adapter is within the
same IP Address range as the access point and gateway. (Since the DWL-7000AP has an IP Address of 192.168.0.50, wireless adapters must have an IP Address in the same range, e.g., 192.168.0.x. Each device must have a unique IP Address; no two devices may have the same IP Address. The subnet mask must be the same for all the computers on the network.) To check the IP Address assigned to the
wireless adapter, double-click on the Local Area Connection icon in
the taskbar > select the Support tab and the IP Address will be
displayed. (Please refer to Checking the IP Address in the Networking Basics section of this manual.)
If it is necessary to assign a Static IP Address to the wireless adapter,
please refer to the appropriate section in Networking Basics. If you are
entering a DNS Server address you must also enter the Default Gateway Address. (Remember that if you have a DHCP-capable router, you will not need to assign a Static IP Address. See Networking Basics: Assigning a Static IP Address.)
39 Troubleshooting (continued) 3. Check that the drivers for the network adapters are installed properly. You may be using different network adapters than those illustrated here, but this procedure will remain the same, regardless of the type of network adapters you are using.
