1 Introduction
The advantages of wireless networks (wireless LANs) are obvious:
Notebooks and PCs can be set up where they are wanted. Problems with
missing ports or construction alterations are a thing of the past with wireless
networking.
Network links in conferences or presentations, access to resources in
adjacent buildings and exchanging data with mobile units are only a few of
the options available with a wireless LAN.
1.1 What is a wireless LAN?
Wireless LANs connect separate units (PCs and notebooks) to a local network
(also LAN –
L ocal A rea N etwork). Unlike conventional LANs, the connection
is established through radio transmission, not via a network cable. For this
reason, wireless LANs are also called
W ireless L ocal A rea N etworks
(WLAN).
All of the standard functions of a wired network are also available in a
wireless LAN: Access to files, servers, printers etc. is possible as is the
integration of the single stations into an internal company e-mail system or
access to the Internet.
1.2 What is required for a wireless LAN?
The question of the required hardware arises in conjunction with the
advantages of a wireless LAN.
1.2.1 Radio interfaces with the network
Every unit in the wireless LAN needs access to the wireless LAN in the form
of a radio interface. Devices that do not come with a standard radio interface,
can be upgraded using an advanced card or an adapter. You use an
AirLancer to upgrade your unit to access the wireless LAN.
A wireless LAN consists of at least two units with radio interfaces. Both units
then communicate directly via radio.
