Biography: Professor Shaofang Gong received his B.Sc. degree in microelectronics from Fudan University, China in 1982, and Licentiate of Engineering and Ph.D. degrees from Linköping University, Sweden in 1988 and 1990, respectively. Between 1991 and 1999, he was a senior researcher with the research institute Acreo Swedish ICT. From 2000 to 2001, he was the chief technology officer at a spin-off company from the research institute. In the meantime, he had an adjunct professorship at Linköping University. Since 2002, he has been chair professor of Communication Electronics at Linköping University. His main research interest has been communication electronics including radio frequency and microwave system design, high speed data transmissions and wireless sensor networks towards Internet of Things. Especially, he together with his team has done long time research on six-port modulation techniques for wireless communications.

Speech Title: Six-port Modulation to Converge Wireless and Optical Networks
Abstract: Today, the Internet based on optical fibers can handle data rates at terabits per second and the cost per bit is decreasing constantly. However, the bottle neck lies after the Internet connection, i.e., the so-called last mile connection to apparatus, often requiring wireless radio links, e.g., at 10 gigabits per second as defined by the 5th generation mobile telephony (5G). Therefore, a good radio technology that can handle the Internet speed has an extremely large potential in the future. During the last decade, researchers at Linköping University in Sweden have been doing research on the Six-port radio technology for high speed wireless data transmissions. The uniqueness of the Six-port radio technology can be summarized as follows. Firstly, it is a post-CMOS radio technology, having much larger data capacity than the traditional radio technology. Secondly, it is low cost, since it can be implemented with printed circuit technology utilizing microwave design principles. At frequencies higher than 20 GHz, the Six-port circuits can also be integrated on silicon or III-V semiconductors, e.g., GaAs.
