Award-winning doctoral dissertation could double the relay capacity of 5G networks

News article

Finnish unions in the technical sector rewarded the best dissertation of the year 2014 in Finland within all engineering sciences. The finding made by Taneli Riihonen in his dissertation could turn out to be a discovery worth hundreds of billions of euros globally that could solve the problem of data relay capacity in congested radio frequencies. The award ceremony was held in Helsinki yesterday.

The doctoral dissertation of Taneli Riihonen, DSc (Tech), “Design and Analysis of Duplexing Modes and Forwarding Protocols for OFDM(A) Relay Links”, is ground-breaking, and it has received great attention internationally. Dr. Riihonen demonstrated that it is possible to almost double the relay capacity of next generation 5G networks. As radio frequencies become more congested, the findings of Dr. Riihonen could turn out to be worth hundreds of billions of euros globally. The full-duplex relaying mode is a new and promising concept that has generated notable international interest, but little scientific research before this. 

Dr. Riihonen prepared his dissertation in Finland for Aalto University School of Electrical Engineering Department of Signal Processing and Acoustics. Professor Risto Wichman was the dissertation supervisor. Currently, Dr. Riihonen is a visiting scholar at Columbia University in New York. 

The value of the award granted by Academic Engineers and Architects in Finland TEK and Tekniska Föreningen i Finland (TFiF) is EUR 7,500. The award is granted annually.
