Figure 1 Infrastructure mode
Ad hoc mode
In ad hoc mode (Figure 2), wireless network adapters work within an independent
basis service set (IBSS) and all stations communicate directly with each other
without using an access point (AP). Ad-hoc mode is also called peer-to-peer
mode.
An ad hoc wireless LAN consists of a group of computers, each of which is
equipped with a wireless adapter card, that is connected by radio signals as an
independent wireless LAN.
In most cases, computers in an ad hoc wireless LAN automatically detect the
channel being used for the ad hoc network. When using ad hoc mode with the 2.4
GHz frequency range, you either can let the computer auto-detect the channel or
manually set the channel. When manually setting the channel, all computers in the
wireless LAN must be configured to the same radio channel.
