21.1 Wireless LAN Overview

This section introduces the wireless LAN (WLAN) and some basic scenarios.

21.1.1 IBSS

An Independent Basic Service Set (IBSS), also called an Ad-hoc network, is the simplest WLAN
configuration. An IBSS is defined as two or more computers with wireless adapters within range of
each other and can set up an independent (wireless) network without the need of an access point (AP).

21.1.2 BSS

A Basic Service Set (BSS) is 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.
