5.1 Wireless LAN Overview
This section introduces the wireless LAN (WLAN) and some basic scenarios.
5.1.1 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 that from an independent (wireless) network without the need of an access point (AP).

5.1.2 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.
