building walls. In some cases, stable connections are
often only possible between WLAN devices within a
single room.
As it is not possible to rely on hardware such as net-
work cables (in a LAN) or household wiring (in a dLAN)
to control access to a WLAN, wireless networking nat-
urally presents special security challenges. WLANs
therefore use a number of security measures, such as a
concealed network name, data encryption and access
control via the MAC addresses of the network adapt-
ers.

2.2.1 Wi-Fi or WLAN?

Wi-Fi is a brand name of the Wi-Fi Alliance, a consor-

many countries, Wi-Fi is also used synonymously with
WLAN, which if taken strictly, is incorrect, because Wi-
Fi designates the wireless standard and WLAN the
wireless network.
