Infrastructure Wireless LAN
The SMC2662W can also provide access to a wired LAN for
wireless workstations. An integrated wired and 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.
