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.
Root Unit on a Wired LAN
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 1-3 shows access points acting as root units on a wired LAN.
