Frequency Range
FRITZ!Box Fon WLAN 7170 – 7 WLAN: Wireless Local Area Network
59
In Europe, 13 channels are provided for WLAN in the 2.4 GHz
range. One channel has a bandwidth of 22 MHz. A 5 MHz in-
terval is left empty between adjacent channels. That means
that channels located directly next to each other may overlap
and result in mutual interference. If several WLANs are oper-
ated within a small space, a distance of at least five channels
should be left empty between each two channels used. For
instance, if channel 1 is selected for one WLAN, the channels
7 through 13 can be selected for a second WLAN. This main-
tains the minimum distance between channels.
Should interference in a WLAN persist, the first step should
be to select a different channel. Additional tips on interfer-
ence in the WLAN radio network are presented in the section
“Eliminating Disturbances Caused by Another WLAN Radio
Network” from page 83.
