Network Configuration Examples
Root Access Point
An access point connected directly to a wired LAN provides a connection point for wireless users. If
more than one access point is connected to the LAN, users can roam from one area of a facility to another
without losing their connection to the network. As users move out of range of one access point, they
automatically connect to the network (associate) through another access point. The roaming process is
seamless and transparent to the user. Figure 1-1 shows access points acting as root units on a wired LAN.

Repeater Access Point
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. The data is sent through the route that provides the best performance for
the client. Figure 1-2 shows an access point acting as a repeater. Consult the “Configuring a Repeater
Access Point” section on page 19-3 for instructions on setting up an access point as a repeater.
Note Non-Cisco client devices might have difficulty communicating with repeater access points.
