Infrastructure Topology
This mode of operation requires the presence of an access point at least. In this mode, all
wireless LAN client devices need to communicate with the access point and then access to a
wired LAN such as Ethernet via the access point. Therefore, an integrated wireless and wired
LAN is called an infrastructure configuration. A group of wireless LAN client users and an
access point construct a Basic Service Set (BSS). Each wireless LAN client devices in this
BSS can talk to any devices in the wired LAN infrastructure via the access point. In this
infrastructure configuration, wireless LAN systems will extend the accessibility to the wired
LAN. On the other hand, infrastructure mode also supports roaming capabilities for mobile
wireless LAN users. More than one BSS can be configured as an Extended Service Set (ESS).
The continuous network allow wireless LAN users to roam freely within an ESS. All wireless
LAN client devices and access points within the ESS must be configured with the same ESS
ID and use the same radio channel.
