Infrastructure Wireless LAN
The SMC2655W access point 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.
