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 adapters (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 clients or between a
wireless client and a wired network client go through one access point (AP).
Intra-BSS traffic is traffic between wireless clients in the BSS. When Intra-BSS is enabled, wireless
client
A
and
B
can access the wired network and communicate with each other. When Intra-BSS is
