Wireless LAN Topologies

This section discusses ad-hoc and infrastructure wireless LAN topologies.
Ad-hoc Wireless LAN Configuration
The simplest WLAN configuration is an independent (Ad-hoc) WLAN that connects a set of
computers with wireless stations (A, B, C). Any time two or more wireless adapters are within
range of each other, they can set up an independent network, which is commonly referred to as
an Ad-hoc network or Independent Basic Service Set (IBSS). The following diagram shows an
example of notebook computers using wireless adapters to form an Ad-hoc wireless LAN.

BSS
A Basic Service Set (BSS) exists when all communications between wireless stations or
between a wireless station and a wired network client go through one access point (AP).
Intra-BSS traffic is traffic between wireless stations in the BSS. When Intra-BSS is enabled,
wireless station A and B can access the wired network and communicate with each other.
When Intra-BSS is disabled, wireless station A and B can still access the wired network but
cannot communicate with each other.
