Ad hoc network
This application is generally called a peer-to-peer network. In the language
of wireless networking, it is known as an ad hoc network.
Infrastructure
network
All computers with wireless network cards are able to access a wired net-
work via an access point. The access point acts as the connection between
the LAN and the WLAN and it also forms the switching center for data traffic
within the WLANs.
A wireless network with a access point is also referred to as an infrastructure
network.
This network type is ideally suited as an addition to existing LANs. The infra-
structure network is the ideal solution for expansion of a LAN in areas where
wiring is not possible or not economical.
Roaming
Multiple access points can be used if the range of a cell is not sufficient to
link all mobile stations. This makes it possible to switch from one wireless
cell to another without interrupting the connection to the network.
