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 providing 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 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 server-based 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
