Infrastructure Wireless LAN
The SMCWPCI-G also provides 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.
