To address the challenges of delivering mobile multimedia simultaneously to millions of wireless consumers in a cost effective way, QUALCOMM developed a new multicasting technology, known as Forward Link Only (FLO) technology. FLO technology is base on OFDM and designed from the ground up for mobility applications to meet demands for wireless multimedia services. In this talk, we first describe the motivation of developing a new technology to satisfy the requirements for multimedia multicasting for mobiles. MediaFLO system and its physical layer, i.e., FLO technology, are then introduced. The designs of FLO technology are described in detail to show how it meets such requirements.

Fuyun Ling received his B. S. degree from Tsinghua University, Beijing, China, in 1968, and his MS and Ph. D. degrees from Northeastern University, Boston, Mass., USA, in 1981 and 1984 respectively. From 1984 to 1998, he was with Motorola Inc. working on research and development of various wireline and wireless communication technologies and products. In 1998, he joined Qualcomm Incorporated, San Diego, California, as a Vice President of Technology and worked on research and development of new wireless communication technologies. Since 2003, he has been working on MediaFLO project and is currently responsible for FLO PHY Layer specification and development. Throughout his career, Dr. Ling has been working on digital communications and digital signal processing and their application to wireless and wireline communications. He holds over 50 US Patents with a number of other patent applications pending. He has also published over 70 papers and two books all in his technical areas. He is an Adjunct Professor of Tsinghua University and a Fellow of IEEE.
