Infrastructure Wireless LANs

The SMC 802.11 N access point (SMCWBR14S-N) can also
provide wireless workstations with access to a wired LAN. 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 extends 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.
