This configuration is called a Basic Service Set (BSS). An Extended Service Set
(ESS) is a set of two or more BSSs forming a single subnetwork. Since most
corporate WLANs require access to the wired LAN for services (file servers,
printers, Internet links) they will operate in infrastructure mode.
Example 1: wireless Infrastructure Mode
Ad hoc mode (also called peer-to-peer mode or an Independent Basic Service
Set, or IBSS) is simply a set of 802.11 wireless stations that communicate
directly with one another without using an access point or any connection to a
wired network. This mode is useful for quickly and easily setting up a wireless
network anywhere that a wireless infrastructure does not exist or is not required
for services, such as a hotel room, convention center, or airport, or where access
to the wired network is barred (such as for consultants at a client site).
