Ad-hoc Wireless LAN Configuration
The simplest WLAN configuration is an independent (Ad-hoc) WLAN that connects a set of computers with
wireless nodes or stations (STA), which is called a Basic Service Set (BSS). In the most basic form, a
wireless LAN connects a set of computers with wireless adapters. 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). See the following diagram of an example of an
Ad-hoc wireless LAN.

Infrastructure Wireless LAN Configuration
For Infrastructure WLANs, multiple access points (APs) link the WLAN to the wired network and allow
users to efficiently share network resources. The Access Points not only provide communication with the
wired network but also mediate wireless network traffic in the immediate neighborhood. Multiple access
