WLAN—Getting Technical
IEEE 802.11a
Because this standard works exclusively in the seldom used
5-GHz range, it offers the opportunity to transmit data rela-
tively free of interference from external influences. WLAN de-
vices that support 802.11a are much less common than de-
vices that work in accordance with the 802.11b/g standard.
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.
However, due to heavy use of the 2.4-GHz range, interference
is more common than in the less-used 5-GHz range.
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, or, if desired, also in the 5-GHz frequency band. Modu-
lation processes and antenna techniques like MIMO (Multiple
Input, Multiple Output) use whichever frequency band is
available more effectively than the older standards.
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).
Thanks to compatibility with the 802.11g standard, you can
also continue to use older WLAN devices.
