The team is carrying on research in the field of future radio communications, and other applications related to the detection of electromagnetic waves. The potential applications include spectrum sensors for cognitive radio systems as well as sensing physical objects based on their electromagnetic properties.

The team is working at Nokia Research Lablet Otaniemi in close cooperation with Helsinki University of Technology and Otaniemi research community.

Research topics

• Spectrum sensor for cognitive radio
• mmW technologies for sensing in intelligent environments
• Nanoelectronics from devices towards circuits, systems and applications
