WLAN (Wireless Local Area Network) is a radio technology
that allows networks and access to the Internet to be provid-
ed without cable connections. This allows multiple users to
share one wireless Internet connection.

Standards

The WLAN standards IEEE 802.11a, IEEE 802.11b,
IEEE 802.11g, IEEE 802.11n and IEEE 802.11i were devel-
oped by the Institute of Electrical and Electronic Engineers
(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 standard.
Standards for the Throughput Rate
Data Throughput
The FRITZ!WLAN USB Stick 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.
Standard Frequency Band Gross Data Throughput up to Net Data Throughput up to
802.11a 5 GHz
802.11b 2.4 GHz
802.11g 2.4 GHz
802.11n 2.4 / 5 GHz
The throughputs listed differentiate between gross and net
transmission rates. The net speed describes the transmission
rate of the user data.
The standard used in a given WLAN depends on the settings
of the WLAN access point.
