WLAN Standards
Standards for the Throughput Rate
Data Throughput
The throughputs listed differentiate between gross and net
transmission rates. The net speed describes the transmission
rate of the user data.
The FRITZ!Box supports your choice of the standards
IEEE 802.11a, 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.
Standard Frequency Band Gross Data Throughput up to Net Data Throughput up to
802.11b 2.4 GHz
802.11g 2.4 GHz
802.11a 5 GHz
802.11n 2.4 / 5 GHz
The standards are intended for different frequency bands.
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.
