In your radio network there are wireless LAN devices that are
compatible with one or both of the following standards:
•
802.11n
•
802.11a
Set the wireless LAN standard for the 5-GHz frequency band
to: 802.11n+a
11ac
In your radio network there are wireless devices that support
the 802.11ac standard:
Set the wireless LAN standard for the 5-GHz frequency band
to: 802.11ac
An unused frequency band can be disabled in the FRITZ!Box
in order to reduce energy consumption without losing wire-
less LAN connections.
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 familiar security mech-
anism WPA (Wi-Fi Protected Access).
The main feature of the extension of WPA to WPA2 is the AES-
CCMP encryption process.
Mechanism
Encryption
WPA
TKIP (Temporary Key Integrity Protocol)
WPA2
TKIP
AES-CCMP
based on the extremely secure AES (Advanced
Encryption Standard) procedure. CCMP
(Counter Mode with CBC-MAC Protocol) de-
fines how the AES procedure is applied to
wireless LAN packets.
