Orthogonal frequency-division multiplexing#FLASH-OFDM

Flash - OFDM stands for Fast Low -latency Access with Seamless Handoff - Orthogonal Frequency Division Multiplexing. It is a method of data transfer for mobile broadband Internet access and is based on the OFDM modulation technique.

Flash - OFDM operates in the UHF frequency band at 450 MHz, and is not compatible with the GSM or UMTS. The technique was developed by the American company Flarion. It can transfer rates of (typically ) 1.5 to 2.5 ( max. 5.1 ) Mbit / s for downlink and 500 to 1000 (max 1800) kbit / s in uplink can be achieved.

The first large-scale commercial Flash - OFDM network was started in October 2005 by T -Mobile in Slovakia.

Among other things, the FLASH-OFDM technology finds use in the mobile Internet connectivity for high-speed trains of the Deutsche Bahn ( Mobility Net).
