8 WLAN: Wireless Local Area Networks
WLAN is a radio technology that allows Ethernet networks
and access to the Internet to be provided without cable con-
nections. This allows multiple users to share one wireless In-
ternet connection. A notebook and a WLAN adapter is all you
need for an Internet connection at locations with public
WLAN access points, for instance at airports.
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).
IEEE 802.11b and IEEE 802.11g
The two standards IEEE 802.11b and IEEE 802.11g define the
transmission rate within a wireless LAN. These standards dif-
ferentiate between gross and net transmission rates. The net
speed describes the transmission rate of the user data.
z A transmission rate of up to 11 Mbit/s can be attained
using 802.11b technology.
z With 802.11g technology, gross transmission rates of up
to 54 Mbit/s are possible. The net rate can reach up to
25 Mbit/s.
The FRITZ!Box Fon WLAN supports both standards. WLAN
adapters based on either of these standards can be used for
WLAN connections with the FRITZ!Box Fon WLAN.
The range within a given WLAN depends to a high degree on
the WLAN adapter used as well as the physical surroundings
of the network.
802.11g++
The transmission rate within a wireless LAN can be boosted
with the 802.11g++ standard. Gross rates of up to 125 Mbit/s
are possible; net transmission rates can reach up to
35 Mbit/s.
