Planet Technology Wireless USB Adapter WL-U350 - Manual (Page 6)

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-U350 equipped PCs configured without
roaming options in an independent BSS must be configured with a BSS ID corresponding to the
WL-U350 used in the BSS. Check your WL-U350 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-U350 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.
Ad-Hoc
An Ad-Hoc wireless LAN is a group of computers, each equipped with one WL-U350 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.
