Section 1 - Product Overview
Introduction
The DAP-2553 802.11n selectable AP increases productivity by allowing you to work faster and more efficiently. With
the DAP-2553, bandwidth-intensive applications like graphics or multimedia will benefit significantly because large files
are now able to move across the network quickly.
The DAP-2553 is capable of operating in one of four different wireless networking modes: access point, WDS (Wireless
Distribution System) with AP, WDS, or Wireless Client mode.
Use less wiring, enjoy increased flexibility, save time and money with PoE (Power over Ethernet).With PoE, the DAP-2553
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 DAP-2553 provides data transfer rates up to 300Mbps. (The 802.11n standard is
backwards compatible with 802.11a, 802.11g, and 802.11b devices.)
WPA/WPA2 is offered in two options: 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. This 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 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.

Section 1 - Product Overview
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
define a list of authorized users who can access the wireless LAN. When attempting to access a wireless LAN with
WPA-Enterprise configured, 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 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 network.
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.
*Maximum wireless signal rate derived from IEEE Standard 802.11 specifications. Actual data throughput may vary. Network conditions
and environmental factors, including volume of network traffic, building materials and construction, and network overhead can lower actual

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 office 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 efficiently. Increased mobility and the absence of cabling and other types of fixed infrastructure have proven to
be beneficial 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 significantly improve the efficiency
of a worker.
Low implementation costs - WLANs are easy to set up, manage, change and relocate. Networks that frequently
change can benefit 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 office.
Inexpensive solution - wireless network devices are as competitively priced as conventional Ethernet network
devices. The DAP-2553 saves money by providing users with multi-functionality configurable in four different
modes.
Scalability - Configurations 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.

Standards-Based Technology
The DAP-2553 Wireless Access Point utilizes the 802.11a, 802.11b, 802.11g, and 802.11n standards.
The IEEE 802.11n standard is an extension of the 802.11a, 802.11b, and 802.11g standards that came before it. It
increases the maximum wireless signal rate up to 300Mbps* within both the 2.4GHz and the 5GHz bands, utilizing* within both the 2.4GHz and the 5GHz bands, 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 simultaneously
transmitted at different frequencies to the receiver. OFDM reduces the amount of crosstalk (interference) in signal
transmissions.
The D-Link DAP-2553 will automatically sense the best possible connection speed to ensure the greatest possible
speed and range.
IEEE 802.11n offers the most advanced network security features available today, including WPA.
*Maximum wireless signal rate derived from IEEE Standard 802.11 specifications. Actual data throughput may vary. Network conditions and environmental factors, including volume of network traffic, building
materials and construction, and network overhead can lower actual data throughout rate.

Wireless Installation Considerations
The D-Link AirPremier N wireless access point lets you access your network using a wireless connection from virtually
anywhere within the operating range of your wireless network. 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:
1. Keep the number of walls and ceilings between the access point and other network devices to a minimum.
Each wall or ceiling can reduce your adapter’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 make a difference. A solid metal door or aluminum studs may have a negative effect
on the range. Try to position access points, wireless routers, and computers so that the signal passes
through drywall or open doorways. Materials and objects such as glass, steel, metal, walls with insulation,
water (fish tanks), mirrors, file cabinets, brick, and concrete will degrade your wireless signal.
4. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that
generate RF noise.
5. If you are using 2.4GHz 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 2.4GHz phone base is as far away from your wireless devices as possible. The base transmits
a signal even if the phone in not in use.
