FRITZ!Box 3490 104
WLAN – technisches Wissen
Bandbreite
Die FRITZ!Box kann abhängig von der zum Einsatz kommen-
den Generation des IEEE 802.11n-Standards, 300 bis
450 Mbit/s über WLAN transportieren. Im IEEE 802ac-Stan-
dard sind bis zu 1300 Mbit/s möglich. Steht im Funkspekt-
rum nicht genügend Raum für eine störungsfreie Übertragung
auf einem Funkkanal mit 40/80 MHz Kanalbandbreite zur Ver-
fügung, reduziert die FRITZ!Box auf 20/40 MHz Kanalband-
breite mit einer entsprechend geringeren Übertragungskapa-
zität.
Bei Verbindungen nach dem 802.11ac-Standard mit drei se-
paraten Datenströmen (drei Antennen) kann mit einer größe-
ren Bandbreite ein höherer Datendurchsatz erreicht werden:
Bei einer größeren Bandbreite ist jedoch auch die Wahr-
scheinlichkeit von Störungen durch benachbarte Funknetze
größer. Große Bandbreiten verkleinern den zur Verfügung ste-
henden Frequenzbereich für benachbarte Funknetze.
Aufteilung der WLAN-Kanäle im 2,4-GHz-Bereich:
