Erstmals 15 Gigabit/Sekunde über 15 Kilometer

Nächste Generation von High-Speed Satellitenfunk

(PresseBox) (Stuttgart, )
Wissenschaftlern der Universität Stuttgart ist es gelungen, eine Datenrate von 15 Gigabit pro Sekunde (Gbit/s) mit einer Richtfunkstrecke im so genannten E-Band über eine Distanz von über 15 Kilometer zu übertragen. Dies entspricht einer Verdreifachung der bisher möglichen Datenrate und Distanz. Die Übertragung war selbst bei Nebel und leichtem Regen möglich. Derartige Richtfunkstrecken können für die nächste Generation der Satellitenkommunikation eingesetzt werden, bei der große Datenmengen vom Satelliten durch die Erdatmosphäre zur Bodenstation gebracht werden müssen. Der gleiche Frequenzbereich ist aber auch für die terrestrische Datenübertragung zugelassen und erfährt aktuell einen weltweiten Aufschwung.
