Infrastructure Wireless LAN

The SMC2755W 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.
