MediaFLO™
The FLO in MediaFLO stands for "Forward Link Only".
MediaFLO technology covers transmission of files and multimedia content from media control to handheld devices. As with DVB-H, MediaFLO uses OFDM transmission with approximately 4,000 (4K) carriers with either QPSK or 16-QAM modulation of the carriers. MediaFLO also uses time division multiplexing, which is similar to what DVB-H refers to as time-slicing, to transmit specific content at specific time intervals. This allows the receiver to be shut down in between these intervals to save power. MediaFLO is mainly used in the US area.
