Fig a-2 An Example of Infrastructure Wireless LAN
WireFree provides access to a wired LAN for wireless workstations. An integrated wireless
and wired LAN is called an Infrastructure configuration. A group of WireFree PC users and a
WAP-1000 Access Point construct a Basic Service Set (BSS). Each WireFree PC in this BSS can
talk to any computer in the wired LAN infrastructure via the WAP-1000 Access Point.
Infrastructure configuration not only extends the accessibility of a WireFree PC to the wired
LAN, but also doubled the effective wireless transmission range for 2 WireFree PCs. Since WAP-
1000 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 WAP-1000. All WireFree PCs configured
without roaming options in this independent BSS must be configured with BSS ID of that WAP-
