79 Chapter 6 Wireless Configuration and Roaming

Intra-BSS traffic is traffic between wireless stations in the BSS. When Intra-BSS is enabled,

wireless station A and B can access the wired network and communicate with each other.

When Intra-BSS is disabled, wireless station A and B can still access the wired network but

cannot communicate with each other.

Figure 22 Basic Service set

6.1.3 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.
