Wireless LAN—Getting Technical
FRITZ!Box 7272
107
IEEE 802.11b
With a maximum throughput rate of 11 Mbit/s, this is the old-
est wireless standard. Older wireless devices of the first gen-
eration can communicate with the FRITZ!Box using 802.11b.
However, if the wireless device supports newer standards
such as 802.11g, the latest standard should be used.
IEEE 802.11g
In this wireless LAN standard data are transmitted in the 2.4-
GHz range at a maximum gross throughput of 54 Mbit/s. This
standard is compatible with a wide range of wireless devices.
IEEE 802.11n
This standard allows for high throughput rates and ranges.
The FRITZ!Box supports 802.11n in the 2.4-GHz frequency
band. Modulation processes and antenna techniques like
MIMO (Multiple Input, Multiple Output) use the frequency
band more effectively than the older standards.
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
.
2.
Enable the advanced view.
3.
Open the “WLAN / Radio Channel” menu and select “Ad-
just radio channel settings” to make the desired chang-
es.
The use of the 802.11n 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).
