IBSS(Independent Basic Service Set) 模式，也叫专属(ad-hoc)模式，是设计来进行点对点的接连的。一群计算机设定相同的 BSS 名称，即可自成一个 group，而此 BSS 名称，即所谓 BSSID。

The IBSS network architecture consists of two or more STAs(stations) communicating directly with each other using 802.11 wireless technology without an AP(Access Point). Most IBSSs are confined to a small number of STAs, and their primary purpose is to provide a short-lived communication session for a specific purpose.

注：IBSS亦可表示“综合业务支撑系统”
