This chapter exemplifies the use of AirLancer radio network cards with the
following example:
5.1 Connecting to a company network
The main advantage of radio networks beside the establishing of indepen-
dent networks is the possibility to extend existing, cable-bound networks. It
does not matter whether the existing LAN has to be extended, the wiring of
new workstations is however uneconomic or impossible, or whether e.g. field
sales representatives need to be integrated mobilely for their office work
time into the corporate LAN.
Example: sales
departement
As example for an infrastructure network we look at the sales department of
a mid-sized company. The sales representatives will move to another floor.
Since they are out of the office most time anyway, their new workplaces are
not wired anymore. Instead, a Wireless LAN access point enables to access
the corporate Intranet services (e.g.
LANCOM 3550 Wireless) . Since the sales
representatives with their notebooks must have access to the network also
in other departments of the company, further base stations will be installed.
These ensure that a sales representative has access to the network within
the company building at any time. When changing to another radio cell, the
stations are disconnected automatically from the previous base station and
connected to the new base station. This procedure is called roaming.
Each sales representative gets a radio network card

notebook, with which he is able to log into the network of the company in his
office. For also being able to print locally, the sales representatives have still
got a network printer in their office, which is attached to the cable-bound
