5. Modifying a Wireless Network
5.1 Infrastructure Mode and Ad Hoc Mode
You can set the Wireless Network Adapter to work in either Infrastructure mode or
Ad Hoc mode.
Infrastructure Mode
In infrastructure mode, devices communicate with each other by first going through
an Access Point (AP). Wireless devices can communicate with each other or can
communicate with a wired network. When one AP is connected to wired network
and a set of wireless stations, it is referred to as a BSS (Basic Service Set).
Ad Hoc Mode
Ad-hoc mode is also called “peer-to-peer mode” or “Independent Basic Service Set
(IBSS)”. In ad hoc mode, devices communicate directly with each other without
using an Access Point (AP).
