The D-Link AirPremier® N DAP-2590 Dual Band PoE Access Point is the ideal solution for enabling selectable dual band wireless connectivity in any business.D-Link, an industry pioneer in wireless networking, introduces a solution for businesses seeking to deploy next generation 802.11n LANs. D-Link unveils its new AirPremier N Dual Band PoE Access Point (DAP-2590), designed specifically for business-class environments such as large or enterprise corporations to provide secure and manageable dual band wireless LAN options for network administrators.

The DAP-2590 allows network administrators to deploy a highly manageable and extremely robust dual band wireless network. All three dual band antennas are detachable and can provide optimal wireless coverage in either 2.4GHz (802.11g and 802.11n) or 5GHz (802.11a and 802.11n) bands. Enclosed in a plenum-rated metal chassis, the DAP-2590 adheres to strict fire codes for placement in air passageways. For advanced installations, this new high-speed Access Point has integrated 802.3af Power over Ethernet (PoE) support, allowing installation of this device in areas where power outlets are not readily available.

The DAP-2590 delivers reliable wireless performance with maximum wireless signal rates of up to 300Mbps¹ in either the 2.4GHz or 5GHz wireless band. This, coupled with support for Wi-Fi Multimedia™ (WMM) Quality of Service features, makes it an ideal access point for audio, video, and voice applications. Additionally, the DAP-2590 supports load balancing features to ensure maximum performance by limiting the maximum number of users per Access Point.

To help maintain a secure wireless network, the DAP-2590 provides the latest in wireless security technologies by supporting both Personal and Enterprise versions of WPA and WPA2 (802.11i) with support for RADIUS server backend. To further protect your wireless network, MAC Address Filtering, Wireless LAN segmentation, Disable SSID Broadcast, Rogue AP Detection, and Wireless Broadcast Scheduling are also included.

The DAP-2590 includes support for up to 8 VLANs for implementing multiple SSIDs to further help segment users on the network. It also includes a wireless client isolation mechanism, which limits direct client-to-client communication.

Additionally, the DAP-2590 supports Network Access Protection (NAP), which is a feature of Windows Server® 2008. NAP allows network administrators to define multiple levels of network access based on individual client’s need. If a client is identified outside of their access area, the client will be automatically brought back to their permitted network access level.

To maximize total return on investment, the DAP-2590 can be configured to optimize network performance based on any one of its multiple operation modes: Access Point, Wireless Distribution System (WDS) with Access Point, WDS/Bridge (No AP Broadcasting) and Wireless Client. With WDS support, network administrators can set up multiple DAP-2590s throughout a facility and configure them to bridge with one another while also providing network access to individual clients. Also included are advanced features such as Load Balancing, which optimizes high network traffic volume, and redundancy for fail-safe wireless connectivity. Additionally, the DAP-2590 offers Spanning Tree Protocol support for greater efficiency and to avoid broadcast storms when used in WDS mode.

Network administrators have multiple options for managing the DAP-2590 including Web (HTTP), Secure Sockets Later (SSL, which provides for a secure connection to the Internet), Secure Shell (SSH, which provides for a secure channel between local and remote computers), and Telnet (bi-directional, eight-bit byte oriented communications facility). For advanced network management, administrators can use the D-Link AP Manager II or D-View SNMPv3 management module to configure and manage multiple access points from a single location. In addition to a streamlined management process, the AP Manager II or D-View software provides network administrators with the means of verifying and conducting regular maintenance checks remotely, eliminating the need to send personnel out to physically verify proper operation.

With the selectable dual band functionality, PoE support, a plenum-rated chassis, extensive manageability, versatile operation modes, and solid security enhancements, the new D-Link AirPremier N Dual Band PoE Access Point (DAP-2590) provides SMB environments with a business-class solution for deploying a wireless network in the workplace.

With the growing number of Internet-enabled applications requiring IP addresses, the supply of IP addresses under the current Internet Protocol version 4 (IPv4) system has already been exhausted. The IPv6 protocol solves this network addressing exhaustion by creating more IP addresses, but migration from IPv4 to IPv6 is not necessarily automatic. But, you don't need to worry about service interruption if you go with D-Link products that are IPv6 Certified. Your network will be automatically IPv4 and IPv6 ready when you use an IPv6-certified D-Link product like his one. With D-Link products, you can rest assured that you'll be covered for the current and the new standards without any hassle to you.
