Infrastructure Wireless LAN
The access point is designed to 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 a connection between
mobile workers, as shown in the following figure.
