In IEEE 802.11 wireless local area networking standards (including Wi-Fi), a service set is a group of wireless network devices that are operating with the same networking parameters. Service sets are arranged hierarchically,: basic service sets (BSS) are units of devices operating with the same medium access characteristics (i.e. radio frequency, modulation scheme etc.), while extended service sets (ESS) are logical units of one or more basic service sets on the same logical network segment (i.e. IP subnet, VLAN etc.). There are two classes of basic service sets: those that are formed by infrastructure mode redistribution points (access points or mesh nodes), and those that are formed by independent stations in a peer-to-peer ad hoc topology. Basic service sets are identified by BSSIDs (basic service set identifiers), which are 48-bit labels that conform to MAC-48 conventions. Logical networks (including extended service sets) are identified by SSIDs (service set identifiers), which serve as "network names" and are typically natural language labels.
