Figure1-3 Access Points as Root Units on a Wired LAN

Repeater Unit that Extends Wireless Range

An access point can be configured as a stand-alone repeater to extend the range of you r 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. You can set up either of the radios in your access point as a repeate r, but one radio must be

set up as a root unit.

Figure 1-4 shows an access point acting as a repeater. Consult the Setting Up a Repeater Access Point,

chp 11 for instructions on setting up the access point as a repeater.

Note Non-Cisco client devices might have difficulty communicating with repeater access points.
