6 WLAN: Wireless Local Area Networks
WLAN is a radio technology that allows Ethernet networks
and access to the Internet to be provided without cable con-
nections. This allows multiple users to share one wireless In-
ternet connection. A notebook and a WLAN adapter is all you
need for an Internet connection at locations with public
WLAN access points, for instance at airports.
Standards
The WLAN standards IEEE 802.11b, IEEE 802.11g and
IEEE 802.11i were developed by the Institute of Electrical and
Electronic Engineers (IEEE).
IEEE 802.11b and IEEE 802.11g
With 802.11b technology, transmission rates of up to
11 Mbit/s are possible; with 802.11g technology, up to
54 Mbit/s. FRITZ!Box Fon WLAN supports both standards.
WLAN adapters based on either of these standards can es-
tablish connections to FRITZ!Box Fon WLAN.
The range within a given WLAN depends to a high degree on
the WLAN adapter used as well as the physical surroundings
of the network.
IEEE 802.11i
The WLAN security concept was expanded with the standard
IEEE802.11i. The term WPA2 is often used in place of
802.11i. WPA2 is an extension of the familiar security mecha-
nism WPA (Wi-Fi Protected Access). The WPA mechanism
stipulates the TKIP (Temporary Key Integrity Protocol) for en-
cryption. The WPA2 mechanism also defines the AES-CCM
encryption procedure, which is based on the AES (Advanced
Encryption Standard) procedure. CCM (Counter with CBC-
MAC) defines how the AES procedure is applied to WLAN
packets.
FRITZ!Box Fon WLAN supports the IEEE 802.11i WLAN stan-
dard and thus the WPA2 mechanism as well.
