MediaFLO is Qualcomm's new technology to broadcast data to portable devices such as cell phones and PDAs. Broadcast data will include multiple real-time audio and video streams, individual, non-realtime video and audio "clips", as well as IP Datacast application data such as stock market quotes, sports scores, and weather reports.[1]

The "F-L-O" in MediaFLO stands for Forward Link Only [2], meaning that the data transmission path is one-way, from the tower to the device. The MediaFLO system transmits data on a frequency separate from the frequencies used by current cellular networks. In the United States, the MediaFLO system will use frequency spectrum 716-722 MHz, which was previously allocated to UHF TV Channel 55.[3][4]

It is a competitor to the Korean T-DMB standard and the European DVB-H standard. Devices including MediaFLO were first introduced by LG and Samsung at CES 2006 in Las Vegas. On December 1st, 2005 Verizon Wireless and Qualcomm announced partnership for the launch of the MediaFLO network, and Verizon launched the service commercially as part of its VCAST offering on March 1, 2007, marketing the MediaFLO-specific technology/service as "VCAST TV"[5]. A similar announcement was made by AT&T Mobility in February 2007.[6] AT&T Mobility launched their MediaFLO servce in May 2008[7]. Qualcomm is also conducting MediaFLO technical trials internationally, with the intention of forming partnerships with existing multi-channel content providers/service operators.
