8More about WLAN
WLAN is a radio technology that allows Ethernet networks and access to
the Internet to be provided without cable connections. This allows multi-
ple users to share one wireless Internet connection.
8.1 Standards
The WLAN standards IEEE 802.11b, IEEE 802.11g and
IEEE 802.11i were developed by the Institute of Electrical
and Electronic Engineers (IEEE).
Standards for the Throughput Rate
Data Throughput The standards IEEE 802.11b and IEEE 802.11g define the
transmission rate within a wireless LAN. These standards
differentiate between gross and net transmission rates. The
net speed describes the transmission rate of the user data.
The standards are intended for different frequency bands.
The FRITZ!Box supports both standards. WLAN adapters
based on one or more of the standards listed can be used
for WLAN connections with the FRITZ!Box.
Range The range within a WLAN is highly dependent on the follow-
ing three factors:
 the WLAN adapter used,
 the structural conditions
 the amount of radio traffic on the same frequency
band. Other WLAN networks, microwave ovens or
Bluetooth transmitters (mobile telephones) may be
active.
