12.1.3 ESS
An Extended Service Set (ESS) consists of a series of overlapping BSS's, each containing an access point,
with each access point connected together by a wired network. This wired connection between access points
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.
