Research within Communication Systems

The division's research issues involve technical and economic aspects of wireless and wired communication systems, fixed and mobile communication systems, communication related services, applications, and usage.

The systems mentioned above are increasingly built using active antenna arrays, distributed computing, and Internet technology. The research activities at the COS division covers technology concepts and implementation aspects of all layers, with particular focus on the physical layer, Media Access and Control (MAC), and network architectures.

This includes, but is not limited to:

  • mobile communication and networking IP over optical, copper and wireless links
  • multi-antenna technology in the form of large arrays, distributed arrays, and reflecting surfaces
  • three-dimensional networks including connected airplanes, drones, and satellites
  • energy-efficient communications and networking
  • wireless localization and sensing
  • local and interdomain routing
  • network architectures and services
  • network operation and service provisioning
  • business models
  • economics and policy issues
