FRITZ!Box Fon WLAN 7113
The range within a WLAN is highly dependent on the fol-
lowing 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.
With a maximum throughput rate of 11 Mbit/s, this is the
oldest standard for radio networks. Older WLAN adapters
of the first generation can communicate with the
FRITZ!Box using 802.11b. However, if the WLAN adapter
supports newer standards such as 802.11g, the latest
standard should be used.
This is currently the most common WLAN standard. It com-
municates with a maximum of 54 Mbit/s gross in the 2.4-
GHz frequency range (ISM) and guarantees broad compat-
ibility with many WLAN devices.
The FRITZ!Box also supports the high-speed mode
802.11g++. The transmission rate within a wireless LAN
can be increased with this extension to as high as
125 Mbit/s gross and 35 Mbit/s net when the remote site
is connected to a WLAN access point compatible with this
mode (an FRITZ!WLAN USB Stick AVM, for example).
The Standard for Security
The WPA2 security mechanism is defined in the
IEEE 802.11i standard. WPA2 is an extension of the famil-
iar security mechanism WPA (Wi-Fi Protected Access).
The main feature of the extension of WPA to WPA2 is the
AES-CCMP encryption process.
