Wireless LAN—Getting Technical
FRITZ!Box 3490 91
IEEE 802.11ac
This standard provides for transmission rates in the gigabit
range. The high throughput rates are achieved using wider
wireless LAN channels, deeper modulation and more MIMO
streams. Channels can be 20, 40, or 80 MHz wide. Modula-
tions of up to 8 bit/256QAM are applied. The standard uses
only the 5-GHz range, which reduces interference with other
users.
This standard is compatible with the 802.11a and 802.11n
standards, which means it can be used with older wireless
devices.
The FRITZ!Box 3490 has a second access point responsible
for the 2.4-GHz range. This allows wireless devices compati-
ble with the 802.11b/g/n to be used as well.
Setting the Right Standard in the FRITZ!Box
The throughput rate that can be achieved in your wireless ra-
dio network depends on the wireless standards used by the
integrated wireless devices. These wireless standards must
also be set in the FRITZ!Box. Proceed as follows to check
which wireless LAN standards are set and change them if
needed:
1. Open the FRITZ!Box user interface; see page 25.
2. Enable the advanced view.
3. Open “WLAN / Radio Channel” and select which wireless
LAN standards should be used for both frequency
bands.
Note the following for the configuration of this setting:
• Your FRITZ!Box 3490 can make two wireless networks
available simultaneously for data transmission. One of
the wireless radio networks works in the 2.4-GHz fre-
quency band, and the other in the 5-GHz frequency
The use of the 802.11ac standard—and thus the availability
of higher throughput rates—is possible only if the wireless
LAN connection is secured using the WPA2 security mecha-
nism (AES-CCMP).
