1.3.2 Infrastructure Configuration
An integrated wireless and wired LAN is called an infrastructure configuration. A group of WLAN PC Card and an
Access Point (AP) is called a Basic Service Set (BSS). Each WLAN PC Card in this BSS can be linked to any
computer in the wired LAN infrastructure via the AP.
Infrastructure configuration not only extends the accessibility of a WLAN PC Card to the wired LAN, but also
doubles the effective wireless transmission range between two WLAN PC Cards.
BSS ID is, in essential, the ID of each independent WLAN PC Card. All WLAN PC Cards configured without
roaming options in this independent BSS must be configured with BSS ID of that AP. You may need to check
BSS ID of your AP by using its vendor supplied program.
Infrastructure configuration is applicable to enterprise scale for wireless access to central database, or wireless
application for mobile workers.
Two APs can be used as a point-to-point link between two LANs. LAN interconnection is applicable to a wireless
backbone between buildings.
