1 Introduction
The models of the LANCOM Router series offer each a DSL or ADSL connector
and also an ISDN connector. The ISDN line can be used as back-up for the DSL
connection, for remote management of the router or as basis for the office
communication via LANCAPI.
In addition to their function as routers between LAN and the Internet, all
models of the LANCOM Router series operate also as base stations for wireless
networks. With the base station you link wireless PCs and notebooks to a net-
work, connect these devices to the existing wired LAN and enable also the
wireless devices to access the Internet.
1.1
What is a wireless LAN?
The following sections describe the functionality of wireless networks
in general. You can see from the table 'What your LANCOM can do'
further below which functions your device supports. Please refer to
the reference manual for further information on this topic.
A wireless LAN connects individual end-user devices (PCs and mobile compu-
ters) to form a local network (also called –
L
ocal
A
rea
N
etwork). In contrast
to a traditional LAN, communication takes place over a wireless connection
and not over network cables. For this reason it is called a
W
ireless
L
ocal
A
rea
N
etwork (WLAN).
A wireless LAN provides the same functionality as a cable-based network:
Access to files, servers, printers etc. as well as the integration of individual
work stations into a corporate mail system or access to the Internet.
There are obvious advantages to wireless LANs: Notebooks and PCs can be
installed where they are needed—problems with missing connections or
structural changes are a thing of the past with wireless networks.
