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).
