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.

Network
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.
