Communication Technology Laboratory

Digitisation, networked computing and the ubiquity of data are megatrends that lead to ever greater and more complex data volumes. Secure and fast data processing and transmission play a key role in the societal context. This is accompanied by the continuous improvement of information and communication systems as well as networks. This is where the research focus of the communication technology laboratory comes in.

 Research focal points

Transmission technology via symmetrical copper cabling

  • Spectral measurements up to the high-frequency range 

  • Data transmission and remote power supply via single-pair cabling (single-pair ethernet)

  • Data transmission up to 100 Gbit/s via four pairs 

  •   Real-time transmission  

  • Remote power supply: Modelling and measurement of warming and the impact on transmission properties. In addition to data transmission, remote power supply of the connected end devices can take place with copper cabling through dual use of the IT infrastructure. This is used, for example, for remote power supply of radio network access points.
