Introduction
Introduction
At up to fifteen times the speed* of previous wireless devices you can work faster and
more efficiently, increasing productivity. With the DWL-7700AP, 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 (802.11a; 802.11b; 802.11g) means that the
DWL-7700AP is versatile enough to allow connection to almost any 802.11 network
or device.
The DWL-7700AP is capable of operating in one of 3 different modes to meet your
wireless networking needs. The DWL-7700AP can operate as an access point, or in
WDS (Wireless Distribution System) with AP , or in WDS mode.
Use less wiring, enjoy increased flexibility, save time and money with PoE (Power over
Ethernet). With PoE, the DWL-7700AP shares power and data over the CAT5 cable,
making the setup of your network less expensive and more convenient.
An ideal solution for quickly creating and extending a wireless local area network
(WLAN) in offices or other workplaces, trade shows and special events, the DWL-7700AP
provides data transfers at up to 54Mbps* when used with other D-Link Air Premier®
or Air Premier AG® products (The 802.11g standard is backwards compatible with
802.11b devices).
WPA is offered in two flavors: EAP (used for corporations), and PSK (used for home
users).
WPA-PSK and WPA2-PSK is directed at home users who do not have the server based
equipment required for user authentication. The method of authentication is similar to
WEP because you define a “Pre-Shared Key” on the wireless router/AP. Once the pre-
shared key is confirmed and satisfied on both the client and access point, then access
is granted. The encryption method used is referred to as the Temporal Key Integrity
Protocol (TKIP), which offers per-packet dynamic hashing. It also includes an integrity
checking feature which ensures that the packets were not tampered with during wireless
transmission. WPA2-PSK is far superior to WPA-PSK, because the encryption of data
is upgraded with the Advanced Encryption Standard (AES).
*Maximum wireless signal rate derived from IEEE Standard 802.11a and 802.11g specifications. Actual data throughput will vary.
Network conditions and environmental factors, including volume of network traffic, building materials and construction, and network
overhead lower actual data throughput rate.

Introduction (continued)
Introduction
WPA-EAP and WPA2-EAP is ideal for businesses that have existing security
infrastructures in place. Management and security implementation can now be
centralized on a server participating on the network. Utilizing 802.1x with a RADIUS
(Remote Authentication Dial-in User Service) server, a network adminstrator can define
a list of authorized users who can access the wireless LAN. When attempting to access
a wireless LAN with either WPA-EAP or WPA2-EAP configured, the new client will
be challenged with a username and password. If the new client is authorized by the
administration, and enters the correct username and password, then access is granted.
In a scenario where an employee leaves the company, the network administrator can
remove the employee from the authorized list and not have to worry about the network
being compromised by a former employee. WPA2-EAP is far superior to WPA-EAP,
because the encryption of data is upgraded with the Advanced Encryption Standard
(AES).
802.1x: Authentication which is a first line of defense against intrusion. In the
authentication process, the Authentication Server verifies the identity of the client
attempting to connect to the network. Unfamiliar clients would be denied access.
EAP (Extensible Authentication Protocol) is available through the Windows XP
Operating System. You will need to use the same type of EAP protocol on all the devices
in your network when using the 802.1x feature.

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 to access the data you
want, when and where you want it. You will be able to enjoy the freedom that wireless
networking brings.
A Wireless Local Area Network (WLAN) is a 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 WLAN 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. The DWL-7700AP saves money by providing
multi-functionality, configurable in one of three different modes.
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-7700AP Wireless Access Point utilizes the 802.11a, 802.11b and the 802.11g
standards.
The IEEE 802.11g standard is an extension of the 802.11b standard. It increases the
maximum wireless signal rate of up to 54Mbps* 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.
The D-Link DWL-7700AP will automatically sense the best possible connection speed
to ensure the greatest speed and range possible.
The DWL-7700AP offers the most advanced network security features available today,
including WPA and WPA2.
In addition to its compatibility with 802.11g and 802.11a devices, the DWL-7700AP
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-7700AP.
*Maximum wireless signal rate derived from IEEE Standard 802.11a and 802.11g specifications. Actual data throughput will vary.
Network conditions and environmental factors, including volume of network traffic, building materials and construction, and network
overhead lower actual data throughput rate.

Wireless Basics (continued)
The D-Link Air Premier® DWL-7700AP 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. 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:
Installation Considerations
1 Keep the number of walls and ceilings between the DWL-7700AP and other network
devices to a minimum - each wall or ceiling can reduce your DWL-7700AP’s range
from 3-90 feet (1-30 meters.) Position your devices so that the number of walls or
ceilings is minimized.
2 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.
3 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.
4 Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or
appliances that generate RF noise.
