Networking / Beginners

Independent networks

On the left is an independent BSS (IBSS). Stations in an IBSS communicate directly with each other and thus must be within direct communication range. The smallest possible 802.11 network is an IBSS with two stations. Typically, IBSSs are composed of a small number of stations set up for a specific purpose and for a short period of time. One common use is to create a short-lived network to support a single meeting in a conference room. As the meeting begins, the participants create an IBSS to share data. When the meeting ends, the IBSS is dissolved.[] Due to their short duration, small size, and focused purpose, IBSSs are sometimes referred to as ad hoc BSSs or ad hoc networks.

IBSSs have found a similar use at LAN parties throughout the world.
