5.1.3 ESS

An Extended Service Set (ESS) consists of a series of overlapping BSSs, each containing an access point,
with each access point connected together by a wired network. This wired connection between APs is called
a Distribution System (DS). An ESSID (ESS IDentification) uniquely identifies each ESS. All access points
and their associated wireless stations within the same ESS must have the same ESSID in order to
communicate.
