points can provide wireless coverage for an entire building or campus. All communications between
stations or between a station and a wired network client go through the access point.

The Extended Service Set (ESS) shown in the next figure consists of a series of overlapping BSSs (each

could be any type of network, it is almost invariably an Ethernet LAN. Mobile nodes can roam between
access points and seamless campus-wide coverage is possible.
