The access point can also provide access to a wired LAN for wireless workstations.
An integrated wired/wireless LAN is called an infrastructure configuration. A Basic
Service Set (BSS) consists of a group of wireless PC users, and an access point that
is directly connected to the wired LAN. Each wireless PC in this BSS can talk to any
computer in its wireless group via a radio link, or access other computers or
network resources in the wired LAN infrastructure via the access point.
The infrastructure configuration not only extends the accessibility of wireless PCs
to the wired LAN, but also increases the effective wireless transmission range for
wireless PCs by passing their signal through one or more access points.
A wireless infrastructure can be used for access to a central database, or for
connection between mobile workers, as shown in the following figure.
