Fig. 2 - Infrastructure Wireless LAN Configuration
The GL2411V1-A provides access to a wired LAN for wireless workstations. An integrated wireless
and wired LAN is called an Infrastructure configuration. A group of GL2411V1-A PC users and an
Access Point compose a Basic Service Set (BSS). Each GL2411V1-A PC in a BSS can talk to any
computer in the wired LAN infrastructure via the Access Point.
An Infrastructure configuration extends the accessibility of a GL2411V1-A equipped PC to a wired
LAN, and doubles the effective wireless transmission range for 2 GL2411V1-A PCs. Since the
Access Point is able to forward data within its BSS, the effective transmission range in an
infrastructure LAN is doubled.

Fig. 3 - The effective Transmission Range
The use of a unique ID in a BSS is essential. All GL2411V1-A equipped PCs configured without
roaming options in an independent BSS must be configured with a BSS ID corresponding to the
GL-2411AP used in the BSS. Check your GL-2411AP for its BSS ID or use the Access Point
Browser Utility program to determine the BSS ID.
The Infrastructure Wireless LAN configuration is appropriate for enterprise-scale wireless access to
a central database, or as a wireless application for mobile users.

9
A point-to-point LAN configuration is possible when two access points are linked with an optional
directional antenna (the directional antenna is an optional accessory, please contact your dealer for
information). The optional directional antenna makes LAN-Interconnection to a wireless backbone
between buildings possible.
2-2 ROAMING
Infrastructure mode also supports roaming capabilities for mobile users. More than one BSS can be
configured as an Extended Service Set (ESS). The continuous network allows users to roam freely
within an ESS. All GL2411V1-A PCs and GL-2411APs within one ESS must be configured with the
same ESS ID and use the same radio channel.

Before enabling an ESS with roaming capability, choosing a feasible radio channel and optimum
Access Point position is recommended. Proper Access Point positioning combined with a clear
radio signal will greatly enhance performance.
