At least 128MB of memory and a 500MHz processor
Introduction
At up to fifteen times the speed of previous wireless devices (up to 108Mbps in Super
AG mode), you can work faster and more efficiently, increasing productivity. With the
DWL-7200AP, bandwidth-intensive applications like graphics or multimedia will benefit
significantly because large files are able to move across the network quickly.
Inclusion of all three standards (802.11g; 802.11a; 802.11b) means that the DWL-7200AP
is versatile enough to allow connection to almost any 802.11 network or device.
The DWL-7200AP has the newest, strongest and most advanced security features
available today. When used with other 802.11 WPA (Wi-Fi Protected Access) compatible
products in a network with a RADIUS server, the security features include:
WPA: Wi-Fi Protected Access which authorizes and identifies users based on a secret
key that changes automatically at regular intervals. WPA uses TKIP (Temporal
Key Integrity Protocol) to change the temporal key every 10,000 packets (a
packet is a kind of message transmitted over a network.) This ensures much
greater security than the standard WEP security. (By contrast, the previous
WEP encryption implementations required the keys to be changed manually.)
For home users that will not incorporate a RADIUS server in their network, the security
for the DWL-7200AP, used in conjunction with other WPA-compatible 802.11 products,
will still be much stronger than ever before. Utilizing the Pre-Shared Key mode of
WPA, the DWL-7200AP will obtain a new security key every time it connects to the
802.11 network. You only need to input your encryption information once in the
configuration menu. No longer will you have to manually input a new WEP key frequently
to ensure security. With the DWL-7200AP, you will automatically receive a new key
every time you connect, vastly increasing the safety of your communication.

Wireless Basics
D-Link AirPremierTM AG 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. Strictly adhering to the IEEE standard, the D-Link
AirPremierTM AG 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.
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.
Inexpensive Solution - Wireless network devices are as competitively priced as
conventional Ethernet network devices.
Scalability - 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.
Wireless Basics (continued)
Standards-Based Technology
The DWL-7200AP Wireless Access Point utilizes the 802.11a, 802.11b and draft 802.11g
standard.
The IEEE 802.11g standard is an extension of the 802.11b standard. It increases the
data rate up to 54Mbps (108Mbps in Super G mode) within the 2.4GHz band. The
802.11a standard also increases the data rate up to 54Mbps, 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-7200AP offers the most advanced network security features available today,
including WPA.
In addition to its compatibility with 802.11g and 802.11a devices, the DWL-7200AP 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-7200AP.
Wireless Basics (continued)
Installation Considerations
Desktop and laptop computers with wireless network adapters installed can access the
D-Link AirPremierTM AG DWL-7200AP 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-7200AP 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 may generate extreme RF noise.
Getting Started
Right out of the box, with its default settings, the DWL-7200AP will automatically connect with other D-Link AirPremierTM AG products.
IP ADDRESS
Note: If you are using a DHCP-capable router in your network 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.
An Infrastructure wireless network contains an access point or router. The
Infrastructure Network example, shown on the following page, contains the following
D-Link network devices:
