network. In case you do not wish to connect to a wired network, but prefer to set up a small independent
wireless workgroup without an AP, use the Ad-hoc (IBSS) (Independent Basic Service Set) mode.
Ad-Hoc (IBSS)
Ad-hoc mode does not require an AP or a wired network. Two or more wireless stations communicate
directly to each other. An ad-hoc network may sometimes be referred to as an Independent Basic Service
Set (IBSS).
Figure 2-1 IBSS Example
Figure 2-2 BSS Example
A series of overlapping BSS and a network medium, such as an Ethernet forms an Extended Service Set
(ESS) or infrastructure network. All communication is done through the AP, which relays data packets to
other wireless stations or devices connected to the wired network. Wireless stations can then access
resource, such as the printer, on the wired network.
