Introduction

The DAP-2553 802.11a/n or b/g/n switchable 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 providing data transfers 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 ﬂavors: 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 serverbased 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 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 deﬁne a list of authorized users who can access the wireless LAN.When attempting to access a wireless LAN with WPA-Enterprisee 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 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

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.

- productivity increases when people can have access to data in any location within

Wireless Basics

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* 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 Basics

Installation Considerations

The D-Link DAP-2553 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 the number of walls and ceilings between the DAP-2553 and other network

devices to a minimum - each wall or ceiling can reduce your DAP-2553’s range by 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

(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.

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.

Keep your product away - at least 3-6 feet or 1-2 meters - from electrical devices

or appliances that generate RF noise.

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.
