NWA5120 Series User’s Guide 13
CHAPTER 1
Introduction
1.1 Overview
This User’s Guide covers the following models: NWA5121-N, NWA5121-NI, and NWA5123-NI. Your
NWA is a wireless AP (Access Point). It extends the range of your existing wired network without
additional wiring, providing easy network access to mobile users.
Your NWA’s business-class reliability, SMB features, and centralized wireless management make it
ideally suited for advanced service delivery in mission-critical networks. It uses Multiple BSSID and
VLAN to provide simultaneous independent virtual APs. Additionally, innovations in roaming
technology and QoS features eliminate voice call disruptions. It can serve as an AP, or even as an
RF monitor to search for rouge APs to help eliminate network threats.
The NWA controls network access with Media Access Control (MAC) address filtering, and rogue
Access Point (AP) detection. It also provides a high level of network traffic security, supporting IEEE
802.1x, Wi-Fi Protected Access (WPA), WPA2 and Wired Equivalent Privacy (WEP) data encryption.
Your NWA is easy to install, configure and use. The embedded Web-based configurator enables
simple, straightforward management and maintenance. See the Quick Start Guide for how to make
hardware connections.
