Comnet study programmes.png

Comnet carries out comprehensive research in the areas of information and communications theory, communications and networking technology, and communications ecosystem. With 13 professors, Comnet is well-positioned to address the grand challenges comnet.aalto.fi/en/research/grand_challenges in the area of communication and networking in a comprehensive fashion covering all the OSI layers from physical to applications and making impact comnet.aalto.fi/en/research/impact  to the society.

The information theory group (Prof. Patric Östergård) study computational methods in discrete mathematics and information theory. Especially, the research focus is on existence and classification problems of mathematical objects.

The communications and networking technology research integrates expertise from Communications theory (Prof. Olav Tirkkonen), communications engineering (Prof. Riku Jäntti and Prof. Jyri Hämäläinen), mobile core networks, network function virtualization and cloud communications (Prof. Tarek Taleb), routing and trust (Prof. Raimo Kantola) and Internet technologies (Prof. Jukka Manner).  The current research focuses on developing advanced radio communication systems and internet technologies for 5th generation mobile communication systems.  There the focus is on flexible spectrum use, Internet of things, ultra-low latency communications, network protocols and software, virtualization and cloudification of networks, network big data, energy efficiency of ICT as well as on network security, trust, and resiliency.

The communications ecosystem research area analyzes the needs, demands, behavior and economics of users, operators and other players of the market place. The research areas is composed of three research groups: The Network Economics group lead by Prof. Heikki Hämmäinen seeks to identify and eliminate techno-economical bottlenecks preventing adaptation of new technologies. The user interfaces research group  lead by Professor Antti Oulasvirta study computational methods for user interface design. The ubiquitous systems group lead by Professor Stephan Sigg studies problems related to context prediction, collaborative transmission in Wireless sensor networks, context-based secure key generation, device-free passive activity recognition and computation of functions in wireless networks at the time of transmission.  Research focuses especially on modeling the user and improving the quality of experience.
