23.1.1 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).
