Project: Real-time Mobile Communication


In this application we propose research in a quit new field - wireless real-time communication. It is true that mobile communication based on radio signals is a vast research field. It is also true that this research is nearly always focused on average behaviour, throughput, and bandwidth utilisation. We foresee a wider use of wireless communication based on radio frequency (RF) signals in industry and transportation. This, however, calls for research efforts leading to new coding/decoding techniques and, protocols for time critical traffic. In this project we intend to address three research topics:

  • New coding and decoding techniques making wireless communication available for time and safety critical applications
  • New network topologies for wireless real-time networks leading to enhanced performance and new applications.
  • Investigating the suitability of existing standards especially ”Bluetooth” for real-time wireless communication.
