Chapter 1 Overview Network Configuration Examples Draft 1A - CISCO CONFIDENTIAL Network Configuration Examples This section describes the access point’s role in three common wireless network configurations. The access point’s default configuration is as a root unit connected to a wired LAN or as the central unit in an all-wireless network. The repeater role requires a specific configuration.
Chapter 1 Overview Network Configuration Examples Draft 1A - CISCO CONFIDENTIAL Repeater Unit that Extends Wireless Range An access point can be configured as a stand-alone repeater to extend the range of your infrastructure or to overcome an obstacle that blocks radio communication. The repeater forwards traffic between wireless users and the wired LAN by sending packets to either another repeater or to an access point connected to the wired LAN.
Chapter 1 Overview Network Configuration Examples Draft 1A - CISCO CONFIDENTIAL Central Unit in an All-Wireless Network In an all-wireless network, an access point acts as a stand-alone root unit. The access point is not attached to a wired LAN; it functions as a hub linking all stations together. The access point serves as the focal point for communications, increasing the communication range of wireless users. Figure 1-8 shows an access point in an all-wireless network.

Glossary Draft 1A - CISCO CONFIDENTIAL W WDS Wireless Domain Services. An access point providing WDS on your wireless LAN maintains a cache of credentials for CCKM-capable client devices on your wireless LAN. When a CCKM-capable client roams from one access point to another, the WDS access point forwards the client's credentials to the new access point with the multicast key. Only two packets pass between the client and the new access point, greatly shortening the reassociation time.
