Infrastructure Wireless LAN
The WN3501C 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.
