Extended Service Set is the definition set forth in the
IEEE 802.11-1999 standard. An
ESS is a set of one or more interconnected
BSSs and integrated local area networks (
LANs) that appear as a single BSS to the
logical link control layer at any station associated with one of those BSSs.
The set of interconnected BSSs must have a common network name or SSID. They can work on the same channel, or work on different channels to boost aggregate throughput.
