Infrastructure

Fig. 2 An Example of Infrastructure Wireless LAN

WL1100B-AP provides access to a wired LAN for wireless workstations. An integrated wireless and

wired LAN is called an Infrastructure configuration. A group of LAN PC users and a WL1100B-AP

Access Point construct a Basic Service Set (BSS). Each LAN PC in the BSS can talk to any computer in

the wired LAN infrastructure via the WL1100B-AP Access Point.

Infrastructure configuration not only extends the accessibility of a LAN PC to the wired LAN, but also

doubles the effective wireless transmission range for 2 LAN PCs. Since WL1100B-AP is able to forward

data within its BSS, the effective transmission range in an infrastructure LAN is

doubled

BSS ID is, in essence, the ID of each independent WL1100B-AP. All LAN PCs configured without

roaming options in the independent BSS must be configured with the BSS ID of the WL1100B-AP.

Infrastructure is applicable in an enterprise scale for wireless access to central databases, or wireless

access for mobile workers.
