Overview of the D-Link Unified Access System

The D-Link Unified Access System is a wireless local area network (WLAN) solution that enables WLAN deployment while providing state-of-the-art wireless networking features. It is a scalable solution that provides secure wireless connectivity and seamless layer 2 and layer 3 roaming for end users.

This chapter contains the following sections:

•D-Link Unified Access System Components

•D-Link Unified Access System Topology

•Understanding the User Interfaces

•Wireless System Features and Standards Support

D-Link Unified Access System Components

The D-Link Unified Access System components include the D-Link WLAN Controller Switch and the D-Link Access Point (AP).

Each D-Link WLAN Controller Switch can manage up to 48 D-Link Access Points, and each access point can handle up to 512 associated wireless clients (256 per radio). The switch tracks the status and statistics for all associated WLAN traffic and devices.

You can configure up to four peer D-Link WLAN Controller Switches that share various information about APs and their associated wireless clients. The peer WLAN switches can be directly connected to each other, separated by layer 2 bridges, or located in different IP subnets. Wireless clients can roam among the access points managed by peer switches without losing network connections.

Whether or not you have a peer group, the D-Link Unified Access System can support a total of 8000 wireless clients.

D-Link WLAN Controller Switch

The D-Link WLAN Controller Switch (WCS) handles Layer 2, 3, and 4 switching and routing functions for traffic on the wired and wireless LAN and manages up to 48 access points (APs).
