Flash-OFDM steht fΓΌr Fast Low-latency Access with Seamless Handoff β Orthogonal Frequency Division Multiplexing. Es ist eine Methode der DatenΓΌbertragung fΓΌr mobilen Breitband-Internetzugang und basiert auf der Modulationstechnik OFDM.
Flash-OFDM arbeitet im UHF-Frequenzband bei 450 MHz und ist nicht kompatibel zu GSM oder UMTS. Die Technik wurde von der amerikanischen Firma Flarion entwickelt.cite-ref-1[1] Es kΓΆnnen DatenΓΌbertragungsraten von (typischerweise) 1,5 bis 2,5 (max. 5,1) MBit/s im Downlink und 500 bis 1000 (max. 1800) kBit/s im Uplink erreicht werden.cite-ref-2[2]
Unter anderem fand die Flash-OFDM-Technologie Einsatz bei der mobilen Internetanbindung von ICE-ZΓΌgen der Deutschen Bahn (Mobility Net).
