MediaFLO was a technology developed by Qualcomm for transmitting audio, video and data to portable devices such as mobile phones and personal televisions, used for mobile television. In the United States, the service powered by this technology was branded as FLO TV.
The "FLO" in MediaFLO stood for Forward Link Only, meaning that the data transmission path is one way, from the tower to the device. The MediaFLO system transmitted data on a frequency separate from the frequencies used by current mobile telephone networks. In the United States, the MediaFLO system used frequency spectrum 716-722 MHzMegaHertz (MHz) 10^6 Hz, which had previously been allocated to UHFUltra High Frequency (300-3000 MHz) TV channel 55.
