Infrastructure Wireless LAN

The access point also provides 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.
