The Standard for Security
31
IEEE 802.11n
This standard allows for high throughput rates and rang-
es. The FRITZ!WLAN Repeater supports 802.11n in the 2.4-
GHz frequency band, or, if desired, also in the 5-GHz fre-
quency band. Modulation processes and antenna tech-
niques like MIMO (Multiple Input, Multiple Output) use
the entire frequency band available more effectively than
the older standards.
The Standard for Security
IEEE 802.11i
The WPA2 security mechanism is defined in the
IEEE 802.11i standard. WPA2 is an extension of the famil-
iar security mechanism WPA (Wi-Fi Protected Access).
The main feature of the extension of WPA to WPA2 is the
AES-CCMP encryption process.
The FRITZ!WLAN Repeater supports the AES encryption
procedure as part of the WPA2 mechanism, and the TKIP
encryption procedure as part of the WPA mechanism. This
means that the FRITZ!WLAN Repeater can be used in com-
bination with any WLAN adapters that also support WPA2
with AES or WPA with TKIP.
The use of the 802.11n standard—and thus the availabili-
ty of higher throughput rates—is possible only if the
WLAN connection is secured using the WPA2 security
mechanism (AES-CCMP).

CCM (Counter with CBC-MAC) defines how
the AES procedure is applied to WLAN
