Chapter 1 Overview

Network Example with Lightweight Access Points

In Figure 1-7, the autonomous unit is configured in workgroup bridge mode and is associated to a Cisco

Aironet root bridge as a wireless bridge device. This configuration allows the Ethernet-enabled devices

pass Ethernet traffic to and from the main LAN using the workgroup bridge. The main advantage of this

configuration is that the wireless communication link can be over a longer distance than an access point

supports. Typically, an access point can communicate over approximately a 1-mile range; however, the

bridge-to-bridge wireless link can communicate over approximately a 21-mile range.

Network Example with Lightweight Access Points

The lightweight access points support Layer 3 network operation. Lightweight access points and

controllers in Layer 3 configurations use IP addresses and UDP packets, which can be routed through

large networks. Layer 3 operation is scalable and recommended by Cisco.

Figure 1-8 illustrates a typical Layer 3 network configuration containing lightweight access points.
