LAN
An ad hoc wireless LAN consists of a group of computers, each equipped with a
wireless adapter, connected via radio signals as an independent wireless LAN.
Computers in a specific ad hoc wireless LAN must therefore be configured to the same
radio channel. An ad hoc wireless LAN can be used for a branch office or SOHO
operation.

The access point can also provide access to a wired LAN for wireless workstations. An
integrated wired/wireless LAN is called an infrastructure configuration. A Basic
Service Set (BSS) consists of a group of wireless PC users, and an access point that is
directly connected to the wired LAN. Each wireless PC in this BSS can talk to any
computer in its wireless group via a radio link, or access other computers or network
resources in the wired LAN infrastructure via the access point.
