Basic Service Set (BSS) or infrastructure network
This WLAN topology requires a specialized station, called an AP. Wireless stations do not communicate
directly with one another, but all communication is passed to the destination via this central AP. APs can be
connected to a wired network via an uplink port. The following example illustrates a BSS:
Extended Service Set (ESS)
When several BSSs are connected to each other via a Distribution System (very often an Ethernet switch),
the WLAN is called an ESS. The distribution system can be either wired or wireless. The following
example illustrates an ESS:
