8.1.2 What You Need To Know About the Wireless Screen
The following terms and concepts may help as you read through this chapter.
BSS
A Basic Service Set (BSS) exists when all communications between wireless
stations or between a wireless station and a wired network client go through one
access point (AP).
Intra-BSS traffic is traffic between wireless stations in the BSS. When Intra-BSS
traffic blocking is disabled, wireless station A and B can access the wired network
and communicate with each other. When Intra-BSS traffic blocking is enabled,
wireless station A and B can still 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).
