Features and Benefits

±Maximum wireless signal rate derived from IEEE Standard 802.11g, 802.11a and Draft 802.11n 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. Environmental

conditions will adversely affect wireless signal range.

±±Please note that operating frequency ranges vary depending on the regulations of individual countries and jurisdictions. The DAP-2590 isn’t supported in the

5.25~5.35 �Hz and 5.47 ~ 5.725 �Hz frequency ranges in some regions.

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-2590

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-2590 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 �Hz and the 5 �Hz bands, utilizing OFDM technology.

± within both the 2.4 �Hz and the 5 �Hz 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 MPE� 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-2590 will automatically sense the best possible connection speed to ensure the greatest possible speed and range.

Note:

802.11n offers the most advanced network security features available today, including WPA.

conditions will adversely affect wireless signal range.

Section ± - Installation

The D-Link DAP-2590 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-2590 and other network devices

to a minimum - each wall or ceiling

can reduce your DAP-2590’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 �Hz 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 �Hz 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.
