12.3 Wireless LAN—Getting Technical
A wireless LAN is based on standards defined by the Institute
of Electrical and Electronic Engineers (IEEE). These standards
describe, for instance, the transmission rate, encryption
methods and frequencies used in a wireless network.
Throughput Rate
The FRITZ!Box supports your choice of the standards
IEEE 802.11b, IEEE 802.11g and IEEE 802.11n. Wireless de-
vices based on one or more of the standards listed can be
used for wireless LAN connections with the FRITZ!Box.
IEEE 802.11b
With a maximum transmission rate of 11 Mbit/s, this is the
oldest wireless standard. Older wireless devices of the first
generation 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 provides for high transmission rates and rang-
es. 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.
