WL-3552 User’s Manual

BSS can talk to any computer in the wired LAN infrastructure via the Access Point.
An Infrastructure configuration extends the accessibility of a WL-3552 equipped PC to a
wired LAN, and doubles the effective wireless transmission range for 2 WL-3552 PCs.
Since the Access Point is able to forward data within its BSS, the effective transmission
range in an infrastructure LAN is doubled.
The use of a unique ID in a BSS is essential. All WL-3552 equipped PCs configured without
roaming options in an independent BSS must be configured with a BSS ID corresponding to
the WL-3552 used in the BSS. Check your WL-3552 for its BSS ID or use the Site Survey
function on Configuration 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.
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 WL-3552 PCs or other IEEE 802.11b compliant
wireless adapter 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.
1.2.2 Ad-Hoc
An Ad-Hoc wireless LAN is a group of computers, each equipped with one WL-3552
adapter or other wireless adapters, connected as an independent wireless LAN. Computers
in a specific Ad-Hoc wireless LAN must be configured to share the same radio channel.
Ad-Hoc wireless LAN configurations are appropriate for branch level departments or SOHO
operations.
