Basic Service Set

Basic Service Set

The basic service set (BSS) is the basic building block of an IEEE 802.11 wireless LAN (according to the IEEE 802.11-1999 standard). In infrastructure mode one access point (AP) together with all associated stations (STAs) is called a BSS.cite web |url=http://standards.ieee.org/getieee802/download/802.11-2007.pdf |accessdate=2008-05-07 |date=2007-06-12 |title=IEEE Std 802.11™-2007, Section 3.16, p. 6] This is not to be confused with the coverage of an AP, which is called Basic Service Area (BSA). An AP acts as a master to control the stations within that BSS. In IBSS mode a set of synchronized STAs, one of which acts as master, forms a BSS. Each BSS is identified by an BSSID. The most basic BSS is two STAs in IBSS mode. In infrastructure mode, a basic BSS consists of at least one AP and one STA.

In infrastructure mode, groups of BSSs can be connected together with the use of a backbone network (distribution system, DS) and form a network called an Extended Service Set.
