MediaFLO™
MediaFLO™ technology covers the transmission of files and multimedia content from media control to handheld devices. The FLO in MediaFLO™ stands for "Forward Link Only". As with DVB-H, MediaFLO™ uses OFDM transmission with approximately 4000 (4K) carriers with either QPSK or 16QAM 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. MediaFLO™ is mainly used in the US.
