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).
