The use of a unique ID in a BSS is essential. All WL11000 equipped PCs configured without
roaming options in an independent BSS must be configured with a BSS ID corresponding to the
WL11000SA used in the BSS. Check your WL11000SA 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.
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.

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 WL11000 PCs and WL11000SAs 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.
