AVM and WLAN
WLAN (Wireless Local Area Network) is a radio technology that allows
networks access to the Internet to be provided without cable connec-
tions. This allows multiple users to share one wireless Internet connec-
tion.
2.1 Standards
The WLAN standards IEEE 802.11a, IEEE 802.11b,
IEEE 802.11g and IEEE 802.11n (on the basis of the pre-
liminary draft 2.0 of the standard) and IEEE 802.11i were
developed by the Institute of Electrical and Electronic En-
gineers (IEEE).
The standards IEEE 802.11a, IEEE 802.11b, IEEE 802.11g
and IEEE 802.11n define the transmission rate within a
wireless LAN. The IEEE 802.11i standard is a security stan-
dard.
Standards for the Throughput Rate
Data Throughput The FRITZ!WLAN Repeater supports the IEEE 802.11n wire-
less standard and is downward compatible to 802.11a, b
and g networks.
The standards are intended for different frequency bands.
The throughputs listed differentiate between gross and
net transmission rates. The net speed describes the trans-
mission rate of the user data.
The standard used in a given WLAN depends on the set-
tings of the WLAN access point.
Standard Frequency Band Gross Data Throughput up to Net Data Throughput up to
802.11a 5 GHz 54 Mbit/s 54 Mbit/s
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 / 5 GHz 300 Mbit/s 100 Mbit/s
