Frequency Ranges

Wireless Network Name (SSID)
In the factory settings of the FRITZ!Box, the name of the wire-
less network (SSID = Service Set Identifier) is set to
"FRITZ!Box 6360 Cable".
If an additional device with the same network name is locat-
ed in the vicinity of your FRITZ!Box it can occur that the WLAN
adapter attempts to register there. Therefore we recommend
changing the preset SSID to a name of your choice.
2.3 Frequency Ranges
WLAN uses the frequency ranges at 2.4 GHz and 5 GHz as its
transmission range.
With the FRITZ!Box you can establish WLAN connections in ei-
ther the 2.4-GHz or the 5-GHz frequency range.
2.4-GHz frequency band
In the 2.4-GHz frequency band WLAN works in the same range
as Bluetooth, microwave devices and various other devices
like radio-controlled toys, garage-door openers and video
bridges. This means that interference may occur within
WLANs operated in the vicinity of such devices. Generally this
has adverse effects on the transmission rate, including abort-
ed connections.
In the 2.4-GHz frequency range the European regulation au-
thorities have designated 13 channels for WLAN. A channel
can have a bandwidth of 20 MHz (throughput up to
130 Mbit/s) or 40 MHz (throughput of up to 300 Mbit/s).
Channels located directly next to each other in the 2.4-GHz
band may overlap and result in mutual interference. For in-
stance, if several WLANs are operated close to each other in
the 2.4-GHz frequency range with a bandwidth of 20 MHz, a
distance of at least five channels should be left empty be-
tween each two channels used. This means that if channel 1
is selected for one WLAN, the channels 6 through 13 can be
selected for a second WLAN. This maintains the minimum dis-
tance between channels.
