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 provides data transfer rates up to 450Mbps. (The 802.11n standard is backwards
compatible with 802.11a, 802.11g, and 802.11b devices.)
WPA/WPA2 is offered in two options: 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. This 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.
