3.1 Application
3.1.1 Ad-hoc configuration
An Ad-Hoc wireless LAN is a group of computers, each equipped with one TWL-C11 adapter, connected as an
independent wireless LAN. Computers in a specific Ad-Hoc wireless LAN must be configured at the same radio
channel. Ad-Hoc wireless LAN is applicable at a departmental scale for a branch or SOHO operation.

Ad-Hoc Configuration
3.1.2 Infrastructure configuration
TWL-C11 provides access to a wired LAN for wireless workstations. An integrated wireless and wired LAN is
called an Infrastructure configuration. A group of TWL-C11 PC users and an Access Point construct a Basic
Service Set (BSS). Each TWL-C11 PC in this BSS can talk to any computer in the wired LAN infrastructure via
the Access Point.
Infrastructure configuration not only extends the accessibility of a TWL-C11 PC to the wired LAN, but also doubled
the effective wireless transmission range for 2 TWL-C11 PCs. Since Access Point is able to forward data within
its BSS, the effective transmission range in an infrastructure LAN is doubled.
BSS ID is, in essential, the ID of each independent TWL-C11. All TWL-C11 PCs configured without roaming
options in this independent BSS must be configured with BSS ID of that TWL-A11. Check your TWL-A11 for its
BSS ID or use the Access Point Browser Utility program.
