access the wired network but cannot communicate with each other.

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).

This type of wireless LAN topology is called an Infrastructure WLAN. The Access

Points not only provide communication with the wired network but also mediate

wireless network traffic in the immediate neighborhood.
