Chapter1 Overview

Network Examples with Autonomous Access Points

Central Unit in an All-Wireless Network

In an all-wireless network, an autonomous access point acts as a stand-alone root unit. The autonomous

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 autonomous access point in an all-wireless network.

Figure1-8 Access Point as Central Unit in All-Wireless Network

Bridge Network with Wireless Clients

The access point supports root bridge and non-root bridge roles used to interconnect a remote LAN to

the main LAN (see Figure 1-9). The bridge units can also support wireless clients.
