Fig An Examp le of Infrastructure Wireless LAN
The 11Mbps Wireless LAN devices provides access to a wired LAN for wireless
workstations. An integrated wireless and wired LAN is called an Infrastructure configuration.
A group of wireless LAN PC users and an Inter-Building Access Point construct a Basic
Service Set (BSS). Each wireless-equipped PC in this BSS can talk to any computer in the
wired LAN infrastructure via the Inter-Building Access Point.
Infrastructure configuration will extend the accessibility of a wireless station to the wired
LAN. Multiple Inter-Building Access Points will allow roaming and it will increase the
transmission range. The Inter-Building Access Point is also able to forward data within its
BSS. The effective transmission range in an infrastructure LAN is
doubled
