GL2411AP-0A 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 GL2411AP-0A
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 GL2411AP-0A 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 GL2411AP-0A 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 GL2411AP-0A. All LAN PCs configured without
roaming options in the independent BSS must be configured with the BSS ID of the GL2411AP-0A.
Infrastructure is applicable in an enterprise scale for wireless access to central databases, or wireless
access for mobile workers.

An Infrastructure configuration also supports roaming capability for mobile workers. More than one BSS
can be configured to be an Extended Service Set (ESS). On account of a continuous connection to the
network, users
within an ESS
can roam freely. All LAN PCs and GL2411AP-0As within one ESS must be
configured with the same ESS ID and at the same radio channel.
