WLAN—Getting Technical
FRITZ!Box 7330 77
The FRITZ!Box supports your choice of the standards
IEEE 802.11b, IEEE 802.11g and IEEE 802.11n. WLAN devices
based on one or more of the standards listed can be used for
WLAN connections with the FRITZ!Box.
IEEE 802.11b
With a maximum throughput rate of 11 Mbit/s, this is the old-
est WLAN standard. Older WLAN devices of the first genera-
tion can communicate with the FRITZ!Box using 802.11b.
However, if the WLAN device supports newer standards such
as 802.11g, the latest standard should be used.
IEEE 802.11g
This is currently the most common WLAN standard. It commu-
nicates with a maximum of 54 Mbit/s gross in the 2.4-GHz
frequency range (ISM) and guarantees broad compatibility
with many WLAN 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.
Thanks to compatibility with the 802.11g standard, you can
also continue to use older WLAN devices.
Standard Frequency Band Gross Data Throughput up to Net Data Throughput up to
802.11b 2.4 GHz 11 Mbit/s 5 Mbit/s
802.11g 2.4 GHz 54 Mbit/s 25 Mbit/s
802.11n 2.4 GHz 300 Mbit/s 150 Mbit/s
The use of the 802.11n standard—and thus the availability
of higher throughput rates—is possible only if the WLAN con-
nection is secured using the WPA2 security mechanism (AES-
CCMP).
