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).
