etwork (LAN). As the usual network cables have been replaced by a
radio link in this case, we also refer to this as a

(WLAN).
Access point
Furthermore, the access point forms the bridge between LAN and WLAN.
The ELSA access point also can function as an Internet router or a wireless
bridge between two ethernet LANs. It has a slot for a wireless network
adapter (
ELSA AirLancer MC-11
) as well as a normal Ethernet connection on
the other side to exchange data between the two networks.
Radio cell
The maximum area in which wireless network adapters in mobile stations
and the access point can reach each other and exchange data is known as a
radio cell.
All of the standard functions of a wired network are also available in a wire-
less network: Access to files, servers, printers etc. is possible as is the inte-
gration of the mobile stations into an internal company e-mail system.

Use the wireless network cards to link two or more computers directly. All
computers in a WLAN can then communicate with one another with no addi-

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.
