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 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 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.

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 (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 the 2.4 GHz and the 5 GHz 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.
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
