D-Link AirPremier N Dual Band Exterior PoE Access Point
The DAP-3520 802.11a/n or b/g/n switchable AP increases productivity by allowing you to work
faster and more efciently. With the DAP-3520, bandwidth-intensive applications like graphics or
multimedia will benet signicantly because large les are now able to move across the network
quickly.
The DAP-3520 is capable of operating in one of ve different wireless networking modes; access
point, WDS (Wireless Distribution System) with AP, WDS, Wireless Client, or WISP Client Router
mode.
Use less wiring, enjoy increased exibility, save time and money with PoE (Power over Ethernet).
With PoE, the DAP-3520 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 ofces
or other workplaces, trade shows, and special events, the DAP-3520 providing data transfers
rates up to 300Mbps. (The 802.11n standard is backwards compatible with 802.11a, 802.11g,
and 802.11b devices.)
Introduction
Introduction
*Maximum wireless signal rate derived from IEEE Standard 802.11 specications. Actual data throughput may vary. Network
conditions and environmental factors, including volume of network trafc, building materials and construction, and network
overhead can lower actual data throughout rate.
WPA/WPA2 is offered in two avors: Enterprise (used for corporations) and Personal (used for
home users).
WPA-Personal and WPA2-Personal are directed towards home users who do not have the
server-based equipment required for user authentication. The method of authentication is similar
to WEP because you dene a “Pre-Shared Key” on the wireless router/AP. Once the pre-shared
key is conrmed and satised at both the client and access point, access is then 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.
WPA-Enterprise and WPA2-Enterprise are ideal for businesses that already have existing security
infrastructures established. 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 administrator can dene a list of authorized users who
can access the wireless LAN. When attempting to access a wireless LAN with WPA-Enterprisee
congured, the new client will be requested to enter a username with a password.. If the new client
is authorized by the administration, and enters the correct username and password, then access
is then granted. In the case where an employee leaves the company, the network administrator
is able to remove the previous employee from the authorized list to avoid compromising the
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 devices in your network when using
the 802.1x feature.

Wireless Basics
D-Link wireless products are based on industry standards to provide high-speed wireless
connectivity that is easy to use within your home, business or public access wireless networks.
D-Link wireless products provides you with access to the data you want, whenever and wherever
you want it. Enjoy the freedom that wireless networking can bring to you.
WLAN use is not only increasing in both home and ofce environments, but in public areas as well,
such as airports, coffee shops and universities. Innovative ways to utilize WLAN technology are
allowing people to work and communicate more efciently. Increased mobility and the absence
of cabling and other types of xed infrastructure have proven to be benecial to many users.
Wireless adapter cards used on laptop and desktop systems support the same protocols as
Ethernet adapter cards, allowing wireless users to use the same applications as those used on
a wired network.
People use WLAN technology for many different purposes:
Mobility - productivity increases when people can have access to data in any location within
the operating range of their WLAN. Management decisions based on real-time information can
signicantly improve the efciency of a worker.
Low implementation costs - WLANs are easy to set up, manage, change and relocate. Networks
that frequently change can benet from WLAN's ease of implementation. WLANs can operate in
locations where installation of wiring may be impractical.
Installation and network expansion - by avoiding the complications of troublesome cables,
a WLAN system can be fast and easy during installation, especially since it can eliminate the
need to pull cable through walls and ceilings. Wireless technology provides more versatility by
extending the network beyond the home or ofce.
Inexpensive solution - wireless network devices are as competitively priced as conventional
Ethernet network devices. The DAP-3520 saves money by providing users with multi-functionality
congurable in four different modes.
Scalability - Congurations can be 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.

DAP-3520 User’s Manual
D-Link AirPremier N Dual Band Exterior PoE Access Point
Standards-Based Technology
The DAP-3520 Wireless Access Point utilizes the 802.11a, 802.11b, 802.11g, and 802.11n (draft)
standards.
The IEEE 802.11n (draft) standard is an extension of the 802.11a, 802.11b, and 802.1g standards
that came before it. It increases the maximum wireless signal rate up to 300 Mbps* within both* within both
the 2.4 GHz and the 5 GHz bands, utilizing OFDM technology.
This means that in most environments - within the specied range of this device - you will be able
to transfer large les 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 simultaneously transmitted
at different frequencies to the receiver. OFDM reduces the amount of crosstalk (interference) in
signal transmissions.
The D-Link DAP-3520 will automatically sense the best possible connection speed to ensure the
greatest possible speed and range.
802.11n offers the most advanced network security features available today, including WPA.

DAP-3520 User’s Manual
D-Link AirPremier N Dual Band Exterior PoE Access Point
Wireless Basics
The D-Link DAP-3520 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:
Keep your product away - at least 3-6 feet or 1-2 meters - from electrical devices
or appliances that generate RF noise.
4
Keep the number of walls and ceilings between the DAP-3520 and other network
devices to a minimum - each wall or ceiling can reduce your DAP-3520’s range
by 3-90 feet (1-30 meters). Position your devices so that the number of walls or
ceilings is minimized.
1
Be aware of the direct line between network devices. A wall that is 1.5 feet thick
(0.5 meters), at a 45-degree angle appears to be almost 3 feet (1 meter) thick. At
a 2-degree angle, the wall appears to be over 42 feet (14 meters) thick! Position
your devices so that the signal will travel straight through a wall or ceiling - instead
of at an angle - for better reception.
2
Building materials can impede the wireless signal - a solid metal door or aluminum
studs can 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 through other materials.
3
Installation Considerations
If you are using 2.4 GHz cordless phones or X-10 (wireless products such as ceiling
fans, lights, and home security systems), your wireless connection may degrade
dramatically or drop completely. Make sure your 2.4 GHz phone base is as far away
from your wireless devices as possible. The base transmits a signal even when the
phone is not in use.
